United States Naval Construction Battalions, better known as the Seabees, form the Naval Construction Force (NCF) of the United States Navy. Their nickname is a heterograph of the first initials "C.B." from the words Construction Battalion. Depending upon the use of the word, "Seabee" can refer to one of three things: all the enlisted personnel in the USN's occupational field-7 (OF-7), all officers and enlisted assigned to the Naval Construction Force, or the U.S. Naval Construction Battalions (CBs).
Naval Construction Battalions were conceived of as a replacement for civilian construction companies working for the US Navy after the United States was drawn into World War II with the Japanese attack on Pearl Harbor on 7 December 1941. At that time the U.S. had roughly 70,000 civilians working on military installations overseas. International law made it illegal for them to resist enemy attack, as to do so would classify them as guerrillas, for which they could be summarily executed, which is exactly what happened when the Japanese invaded Wake Island.
The Seabees would consist of skilled workers that would be trained to drop their tools if necessary and take up their weapons at a moment's notice to defend themselves. The concept model was that of a USMC-trained battalion of construction tradesmen (a military equivalent of those civilian companies) that would be capable of any type of construction, anywhere needed, under any conditions or circumstance. It was quickly realized that this model could be utilized in every theater of operations, as it was seen to be flexible and adaptable.
The use of USMC organization allowed for smooth co-ordination, integration or interface of both the NCF and Marine Corps elements. In addition, Seabee Battalions could be deployed individually or in multiples as the project scope and scale dictated. What distinguishes Seabees from Combat Engineers are the skill sets. Combat Engineering is but a sub-set in the Seabee toolbox. They have a storied legacy of creative field ingenuity, stretching from Normandy and Okinawa to Iraq and Afghanistan. Admiral Ernest King wrote to the Seabees on their second anniversary, "Your ingenuity and fortitude have become a legend in the naval service." Seabees believe that anything they are tasked with they "Can Do" (the CB motto). They were unique at conception and remain so today. In the October 1944 issue of Flying magazine the Seabees are described as "a phenomenon of World War II". In 2017, the Seabees celebrated their 75 years of service without having changed from Admiral Ben Moreell's conceptual model.
In 1917, the Twelfth Regiment (Public Works) was organized at Naval Training Station Great Lakes. When the US entered World War I in April 1917, the Navy had an immediate requirement to expand the Great Lakes Station in order to house, process, and train 20,000 naval recruits, this number would rise to 50,000 by the end of the year. Lieutenant Malachi Elliott, a graduate of the US Naval Academy, was appointed Public Works Officer at Great Lakes on 18 June 1917, at which time about 500 enlisted men had been assigned to the Public Works Department.
Seeing that the department would need to expand with skilled craftsmen, architects, draftsmen, designers, and other professional and technical people, he began to screen incoming recruits with these skills. Finding many, but not enough, he expanded to recruiting civilians outside of the installation, getting many men willing to join the Navy as petty officers, with the understanding that qualified men could later apply for commissions. This allowed the Public Works Department to grow to nearly 600 men by July 1917.
They were organized into the Twelfth Regiment (Public Works), which was essentially the Public Works Department because staff officers could not exercise military command. Lieutenant William C. Davis was appointed commanding officer of the regiment, he exercised military control, but the Public Works Officers exercised technical control.
In October 1917, the regiment began building Camp Paul Jones at San Diego. With its completion, on 30 December 1917, the regiment became "fully operational" with 1,500 men organized into three battalions. By April 1918, the regiment consisted of 2,400 in five battalions. Men were withdrawn for assignments in the US and abroad.
In spring of 1918, 100 men were given special mechanics and ordnance training before being sent to St. Nazaire, France, to assemble Naval Railway Batteries. Later they would join the gun crews and perform combat duties along the railway lines in proximity to the German lines.
The Twelfth Regiment reached its peak strength 5 November 1918; 55 officers and 6,211 enlisted men formed into 11 battalions. However, with the end of the war on 11 November 1918, the regiment gradually faded away by the end of 1918.
In the early 1930s, the idea that the Twelfth Regiment pioneered was still in the minds of many Navy Civil Engineers. The planners of the Bureau of Yards and Docks (BuDocks) began providing for "Navy Construction Battalions" in their contingency war plans. In 1934 Captain Carl Carlson's version of the plan was circulated to the Navy Yards, this idea of "Navy Construction Battalions" would later be tentatively approved by Chief of Naval Operations, Admiral William Harrison Standley.
In 1935, Rear Admiral Norman Smith, Chief of BuDocks, selected Captain Walter Allen, the War Plans Officer, to represent BuDocks on the War Plans Board. Captain Allen presented the bureau's concept of "Naval Construction Battalions" to the Board. The concept was later adopted for inclusion in the Rainbow war plans.
A major weakness to this "Navy Construction Battalions" concept was that there would be dual control of the battalions; military control would be exercised by Navy officers while the construction side would be controlled the Navy Civil Engineer Corps officers. There would be no provision for good military organization and military training, which was felt to be requisite to creating high morale, discipline, and cooperation among the men. The plans also only allowed for the battalions to be formed to build training stations throughout the US and only on completion be moved to forward areas.
Rear Admiral Ben Moreell became the Chief of BuDocks in December 1937, a post he would hold through the war. With tensions rising in both Europe and Asia, authorization was sought, and quickly received, by the United States Congress for expansion of naval shore bases. New construction was started in the Caribbean and Central Pacific in 1939. These were awarded to private construction firms that would perform the work with civilian personnel under the administrative direction of a Navy Officer in Charge of Construction.
By summer of 1941 civilian contractors were working on large naval bases at Guam, Midway, Wake, Pearl Harbor, Iceland, Newfoundland, Bermuda, and many other places. BuDocks decided there was a need to improve the Navy's supervision of these projects through the creation of "Headquarters Construction Companies". The men in these companies would report to the Officers in Charge of Construction and would be draftsmen and engineering aids needed for the administrative functions of the inspectors and supervisors overseeing the contracted work. These companies would consist of two officers and 99 enlisted men, but were not to do any actual construction. Rear Admiral Chester Nimitz, Chief of the Bureau of Navigation, authorized the formation of the first Headquarters Construction Company, on 31 October 1941. Recruitment started in November and as history would have it the company was formed on 7 December with the men undergoing boot training at Naval Station Newport, Rhode Island. By 16 December 1941, four additional companies had been authorized, but 7 December happened, plans changed and with them the ratings needed by a change in mission. The first HQ Construction Company provided the nucleus for the formation of the 1st Naval Construction Detachment sent to Bora Bora in January 1942. Those men were part of Operation Bobcat and are known in Seabee history as the "Bobcats". In December 1941, Rear Admiral Ben Moreell, Chief of BuDocks, recommended establishing Navy Construction Battalions and on the 28th requested authority to carry this out. On 5 January 1942, he got the go-ahead from the Navy's Bureau of Navigation to recruit construction tradesmen for three Naval Construction Battalions. When Admiral Moreell submitted his request to form those Battalions the other four HQ Construction Companies had been approved and authorized, so HQ Companies 2 & 3 were combined to form the 1st Naval Construction Battalion (and then were deployed as the 2nd & 3rd Construction Detachments) followed by HQ Companies 4 & 5 being combined to form the 2nd Naval Construction Battalion (and deployed as the 4th and 5th Construction Detachments). While those four HQ Companies provided the nucleus for two Construction Battalions they were all deployed in a manner similar to the First Construction Detachment and this sort of thing continued through the 5th NCB. It was 6 NCB that was the first Battalion to deploy as a unit to the same place.
Before all this could happen, a major problem still confronting BuDocks was who would command the Construction Battalions. Naval regulations stated that military command of naval personnel was strictly limited to line officers, yet BuDocks deemed it essential that these Construction Battalions be commanded by officers of the Civil Engineer Corps, who were trained in the skills required for construction work. The newly formed Bureau of Naval Personnel (BuPers), successor to the Navy's Bureau of Navigation, strongly opposed this proposal. Admiral Moreell took the question personally to the Secretary of the Navy, Frank Knox, who, on 19 March 1942, gave authority for officers of the Civil Engineer Corps to exercise military authority over all officers and enlisted men assigned to construction units. Two weeks prior on March 5, all Construction Battalion personnel were officially named Seabees by the Department of the Navy. Seabees have observed that date as their birth date since 1955. Before that Dec 28 was the date the NCF observed.
The first men in the Seabees were not raw recruits trade wise, they were recruited for their experience and skills and were given advanced rank for it. As a group they were the highest paid the United States had in uniform during WWII. To find the men with the necessary qualifications, physical standards were less rigid than other branches of the armed forces. The age range was 18-50, with the average of 37, during the first years of the war. Even so- they all were put through the same physical training. These first men had helped build Hoover Dam, the national highways, and New York's skyscrapers; who had worked in mines and quarries and dug subway tunnels; who had worked in shipyards and built docks and wharfs and even ocean liners and aircraft carriers. After December 1942, President Franklin D. Roosevelt ordered that men for the Construction Battalions had to be obtained through the Selective Service System. By that time 60 CBs had been formed. However, men could enlist and then volunteer for the Seabees with a written statement that they were trade qualified.:136 This lasted until October 1943 when voluntary enlistment in the Seabees ceased until December 1944.:136 During this period the recruits were generally younger and had much less developed skill sets due to their age. By the end of the war 325,000 had enlisted in the Seabees, with training in more than 60 skilled trades. Almost 11,400 officers would join the Civil Engineer Corps during World War II with 7,960 of them having served with the Seabees.
Recruits would receive three weeks of training at Camp Allen, Norfolk, Virginia. Camp Bradford at Little Creek, Virginia replaced Camp Allen which in turn was replaced by Camp Peary, Williamsburg, Virginia(Fig. 5) which was replaced in 1944 by Camp Endicott. The first five battalions were sent directly overseas because of the urgent need of immediate construction of war dictated infra-structure. The newly formed battalions that followed, would be sent to one of the Advance Base Depots and Naval Training Centers (NTC) at Davisville, Rhode Island, Gulfport, Mississippi, or Port Hueneme, California. The Davisville Advanced Base Depot became operational in June 1942, and on 11 August 1942, the Naval Construction Training Center (NTC), known as Camp Endicott, was commissioned. That Camp trained over 100,000 Seabees during World War II. Camp Thomas, a personnel-receiving station on the base, was established in October. Camp Rousseau at Port Hueneme became operational in May 1942. This base was responsible for staging about 175,000 Seabees directly to the efforts in the Pacific. The other CB Camps were: Camp Holliday, Gulfport Mississippi, Camp Parks, Livermore, California, and Camp Lee-Stephenson, Quoddy Village, Eastport, Maine.
CBs sent to the Pacific were attached to one of the four Amphibious Corps: I, III, and V were U.S. Marine Corps (under Admiral Nimitz - Pearl Harbor, Territory of Hawaii) while VII was U.S. Army (under General MacArthur - Brisbane, Australia).
The original purpose of the Seabees was the construction of Advance Bases in the Pacific as laid out by the Office of Naval Operations. These bases were code-named: i.e. BOBCAT (this was the small first Advance Base Operation at Bora Bora), and then came LIONs, CUBs, OAKs and ACORNs. The names were metaphors for base size with LION being a Main Fleet Advance Base (these were numbered 1-4 with Lion 1 on Espiritu Santo). A CUB was a Secondary Fleet Base (these were numbered 1-12, starting with Efate, Tongatabu, and Munda) and were 1/4 the size of a Lion. OAK and ACORN were the names given repurposed enemy air bases captured in an amphibious assault. (CBs constructed, repaired or upgraded 111 major airfields with the number of Acorn fields unknown) Acorn 1 was built at Aola, Guadalcanal, Acorn 8 was on Munda, Acorn 15 was Bougainville, Acorn 17 was on Tarawa. and Acorn 23 was on Kwajalein When these plans were drawn up it was thought that two CBs would be what was needed to construct a Lion installation. This basic idea so grew and evolved that with the invasion of Okinawa the U.S. Navy put 4 Naval Construction Brigades of 55,000 Seabees on that island. This was not Combat Engineering. This was building the infra-structure required to take the War to Japan. Along the way, the Navy had realised that it also needed Advance Base Construction Depots (ABCDs) to get the job done. So the Seabees built them at: 1. Nouméa, 2. Pearl Harbor, 3. Brisbane, 4. Milne Bay, 5. Samar, 6. Subic Bay, and 7.Okinawa). By the end of 1943 the Seabees had constructed over 300 different advanced bases on as many islands. More than 325,000 men served with the Seabees in World War II, fighting and building on six continents and hundreds of islands. In the Pacific, they built 111 major airstrips, 441 piers, bridges, roads, tanks for the storage of 100,000,000 US gal (380,000,000 l; 83,000,000 imp gal) of fuel, hospitals for 700,000 patients, and housing for 1.5 million men.
USMC historian Gordon L. Rottman wrote "that one of the biggest contributions the Navy made to the Marine Corps during WWII was the creation of the Seabees". In turn, the Corps would be influential upon the CB organization and its history. In 1942 the Marines issued USMC duffel bags and uniforms to Battalions 17-20. In the records of both the 18th and 19th NCBs they each claim to have been the first CB authorized to wear the USMC uniform. They both received their military training and USMC issue at Marine Training Center, New River, N.C. Marine Corps Base Camp Lejeune. How many other Battalions received the USMC issue is not recorded but it is known that the 25th, 31st, 43rd, 76th, 121st and 133rd NCBs did also. The Marine Corps listed CBs on their Table of organization: "D-Series Division" for 1942, "E-Series Division" for 1943, and "Amphibious Corps" for 1944/45 But, starting with the 1st Naval Construction Detachment (a.k.a. Bobcats), the Marines redesignated them the 3rd Battalion 22nd Marines. They were the very first Seabees and that was only the beginning. Right after them part of the 4th Naval Construction Detachment was assigned to the 5th Marine Defense Battalion on Funafuti for two years. The Bureau of Yards and Docks original request of 28 December 1941 was for the authorization of three Naval Construction Battalions.:Paragraph 13 When those three Battalions were formed the Seabees did not have a fully functional base of their own. So, upon leaving Navy boot camp, those men were sent to National Youth Administration camps in Illinois, New Jersey, New York and Virginia to receive military training from the Marine Corps.:138
It is written that at that time the Marine Corps wanted a Seabee Battalion for each Division in the Pacific, but was told no because of war priorities.:Paragraph 39 However, by autumn 1942, things changed with NCBs 18, 19 and 25 being assigned to Marine Divisions as combat engineers. Those Battalions were posted to composite Engineer Regiments and redesignated as the 3rd Battalion in their Regiment. (See 16th Marine Regiment, 17th Marine Regiment(Fig. 8), 18th Marine Regiment,19th Marine Regiment, and 20th Marine Regiment.) In August 1942, C Company 18th NCB was transferred to the C.B. Replacement Group, Fleet Marine Force, San Diego. The rest of the 18th embarked from the Fleet Marine Force Base Depot, Norfolk, VA, en route to Guadalcanal where they would replace the 6th NCB with the 1st Marine Division. In the fall of 1943 two sections of the 6th Special NCB were sent to the Russell Islands with the 4th Marines Advance Depot. In November, the 14th NCB landed with the 2nd Raider Battalion on Guadalcanal. Earlier in June the 24th NCB supported the landing of the 9th Marine Defense Battalion on Rendova. The 33rd CB had 202 men posted to the 1st Pioneers as shore party to the 5th Marines of the 1st Marine Division on Peleliu. Along with them were 241 from the 73rd CB. Also attached to the 1st Pioneers was the entire 17th Special NCB (segregated). The 47th sent a detachment to Enogi Inlet on Munda attached to the 1st and 4th Marine Raiders. On Bougainville Commander Brockenbrough of the 71st CB was named the shore party commander for the 3rd Marine Division with his Battalion supported by elements of the 25th, 53rd, and the 75th CBs (and as well as the Marines). The 75th had a 100-man detachment volunteer to land with a Company of 3rd Marines at Cape Torokina, Bougainville. The 53rd also had detachments land as shore parties for the 2nd Raider Battalion on green beach and the 3rd Raider Battalion over on Puruata Island.(Fig. 2) The 121st was formed at NCB Training Center of the Marine Training Center - Camp Lejuene, New River, NC. There it was attached to the 4th Marine Division and assigned as the 3rd Battalion 20th Marines. In 1944 the Marine Engineer Regiments were inactivated. Even with the Engineer Regiments inactivated Marine Divisions still had a CB Battalion posted to them. For Iwo Jima, the 133rd and 31st NCBs were "attached"on temporary duty assignment (TAD) to the 4th and 5th Marine Divisions. For Okinawa it was the 58th, 71st, and 145th NCBs that were TAD to the 6th, 2nd, and 1st Marine Divisions. But, going back again to Iwo Jima, there the 31st and 133rd were not re-designated. The Marines were short of Marines and the Seabees were "tasked" with the assignment. C Co 31st NCB was a component of the 5th Shore Party Regiment and was on the beach on D-day. The 31st NCB's Demolitions echelon was under divisional control through D+10 with the 5th Marine Division. The 133rd was posted to the 23rd Marines as their Shore Party. The Battalion had each Company detached and tasked to the assault as follows: A Co - 1/23, B Co - 2/23, C Co - 3/23, and D Co - 2/25 (see Naval Mobile Construction Battalion 133).The overall command of the Iwo Jima shore parties was the 8th Marine Field Supply Depot. A chief and 25 heavy equipment operators from the 8th CB were attached for the assault.
With Iwo Jima secured the 5th Marine Division returned to Camp Tarawa where it was joined by the 116th NCB. In August Japan fell and 116th NCB went with the 5th Marine Division as part of the occupation force. V-J day found thousands of Japanese troops still in China and the Third Marine Amphibious Corps was sent there to get them back to Japan. A portion of the 33rd Naval Construction Regiment was assigned to III Marine Amphibious Corps for this mission: i.e. the 83rd, 96th, 122nd CBs and the 33rd Special CB.
As just mentioned CB Battalions were also attached to the various Amphibious Corps. The 19th NCB was assigned to the I Marine Amphibious Corps (I MAC) prior to being assigned to the 17th Marines. The 53rd NCB was first posted to I MAC and redesignated "Naval Construction Battalion 1st M.A.C.(Fig. 7). Then when I MAC was redesignated III Amphibious Corps the battalion became an element of the 1st Provisional Marine Brigade until it was disbanded 9 September 1944. For Guam, III Amphibious Corps had the 2nd Special NCB, 25th and 53rd NCBs. V Amphibious Corps (VAC) had the 23rd Special and 62nd NCBs on Iwo Jima. Back on Tinian the 6th Naval Construction Brigade incorporated VAC's insignia as a part of the Brigade's indicating the entire brigade was attached to V Amphibious Corps. (the 6th Brigade was composed of: the 29th Rgt. with CBs; 18, 50, 92, 107, & 135, the 30th Rgt. with CBs: 13, 67, 121,& 123, and the 49th Rgt. with CBs: 9, 38, 110, & 112th (and the 27th Special).
With the war over the Seabees ended up with the most unique standing any U.S. military component has with the U.S. Marine Corps. Seabee historian William Bradford Huie wrote "that the two have a camaraderie unknown else-wheres in the United States military". It should be added that even though they are "Navy" the Seabees adopted USMC fatigues with a Seabee insignia in place of the EGA. During WWII a number of CBs adapted USMC insignia for their units, these included CBs 19, 25, 53, 117 and the 6th Brigade. The insignia modified were the globe and anchor, bulldog, gator with three stars, and a divisional crest.
Naval Combat Demolition Units: NCDUs
In early May 1943, a two-phase "Naval Demolition Project" was directed by the Chief of Naval Operations "to meet a present and urgent requirement". The first phase began at Amphibious Training Base (ATB) Solomons, Maryland with the establishment of Operational Naval Demolition Unit No. 1. Six Officers and eighteen enlisted men reported from NTC Camp Peary dynamiting and demolition school, for a four-week course. Those Seabees were immediately sent to participate in the invasion of Sicily.Naval Combat Demolition Units (NCDUs) consisted of one junior CEC officer and five enlisted and were numbered 1-212. After that first group had been trained Lt. Commander Draper Kauffman was selected to Command the program that had been set up in Camp Peary's "Area E" close to the Seabee Dynamiting and Demolition school. Six classes were graduated from Camp Peary before the program was moved to Fort Pierce. Another reason for the initial NCDU location being at Camp Peary was that the Joint Army Navy Experimental Testing(JANET) site, for beach obstacle removal Project DM-361, was located at Camp Bradford temporarily late 1942-43. Later, despite the move to Fort Pierce, Camp Peary was Kauffman's manpower source. "He would go up to Camp Peary's Dynamite School, assemble the (Seabees) in the auditorium and say, 'I need volunteers for hazardous, prolonged and distant duty." Fort Pierce had Construction Battalion Unit 1011 assigned to the school. Its job was to construct and maintain the various obstacles needed for the demolitions class to practice their training. The men in those classes referred to themselves as "Demolitioneers". The NCDUs had 34 teams in England for the invasion of Normandy.(all told they suffered 53 percent casualties on Normandy). While waiting for D-day the NCDUs trained with the 146th, 277th and 299th Combat Engineer Battalions. Each NCDU had 5 men from a Combat Engineer Battalion attached to the team. In the beginning the first 10 NCDUs were split into 3 groups. The whole thing was a bit ad-hoc as they had no Commanding Officer, but the Senior officer was the leader of group III, Lt Smith (CEC). He served in that capacity unofficially for the entire group. His group III did a lot of experimental demolitions work and developed the Hagensen Pack. As more teams arrived a NCDU Command was created for the invasion. With Europe invaded most of the NCDUs were sent to Fort Pierce and integrated into the UDTs for the Pacific campaign. However, 30 NCDUs were also sent to the Pacific with NCDUs 1-10 staged at Turner City, Florida Island in the Solomons during January 1944. A few were temporarily attached to UDTs. Later NCDUs 1-10 were combined to form Underwater Demolition Team Able. This team was disbanded with NCDUs 2 and 3 plus 19, 20, 21 and 24 being assigned to MacArthur's 7th Amphibious force and were the only NCDUs remaining at the war's end. The other men from Team Able were assigned to numeric UDTs.
Underwater Demolition Teams: UDTs
In November 1943 the Navy learned a hard lesson with underwater obstructions with the invasion of Tarawa. Rear Admiral Kelly Turner ordered the formation of nine Underwater Demolition Teams to deal with the problem. Six would be permenantly assigned to the Central Pacific and three to the South Pacific. UDTs 1 & 2 were completely Seabees according to the UDT Archives with Seabees making up the vast majority of the men in teams 1-9 and 13. Seabees were roughly 20% of UDT 11. The officers were mostly CEC. The first Underwater Demolition Team commander was Cmdr. E.D. Brewster (CEC) UDT 1. When Teams 1 and 2 were initially formed they were "provisional" with 180 men total. The core of these teams came from the Seabees VAC had already gathered in Hawaii. They wore fatigues with life-vests and were not expected to leave their boats similar to the NCDUs. However, at Kwajalein Fort Pierce protocol was changed. Admiral Turner ordered daylight reconnaissance, and Ens. Lewis F. Luehrs and Seabee Chief Bill Acheson wore swim trunks under their fatigues. They stripped down, spent 45 minutes in the water in broad daylight. When they got out were taken directly to Admiral Turner's flagship, still in their trunks, to report. Admiral Turner concluded that daylight reconnaissance by individual swimmers was the way to get accurate information on coral and underwater obstacles for upcoming landings. This is what he reported to Admiral Nimitz. The success of those UDT 1 Seabees not following Fort Pierce protocol rewrote the UDT mission model and training regimen.Ensign Luehrs and Chief Acheson were each awarded a Silver Star for their exploit. Three days after requesting the UDTs Admiral Turner requested the creation of a "Naval Combat Demolition Training & Experimental Base" at Kihei, Hawaii on Maui. The actions of UDT 1 were immediately incorporated in the training and made it distinctly different from that at Fort Pierce. The first head of training was Seabee Lt. T.C. Crist, Supply Officer of UDT 2 (Roi-Namur and awarded silver star for there). He was in that position briefly from when UDTs 1 &2 decommissioned and being named Commander of UDT 3(Fig 11). The actions of Ens. Luehrs and Seabee Acheson created the image of UDTs as the "naked warriors". Later, UDT 13 would be on the beach at Iwo Jima. They scouted prior to D-day, helped direct the first landing craft to the correct beaches on D-day and helped clear the beaches of debris on D-plus 2. UDT 14 was the first "all Fleet team" even though the Commander and XO were both CEC (Ltjg A.B. Onderdonk and Ltjg C.E. Emery). After July 1944 new UDTs were completely USN with no Army or USMC. At wars end 34 teams had been formed with teams 1-21 having actually been deployed. The Seabees provided half of the men in the teams that saw service. The U.S. Navy did not publicize the existence of the UDTs until post war and when they did they gave credit to Lt. Commander Kauffman and the Seabees. During WWII the Navy did not have a rating for the UDTs nor did they have an insignia. Those men with the CB rating on their uniforms considered themselves Seabees that were doing underwater demolition(Fig. 11). They did not call themselves "UDTs" or "Frogmen" but rather "Demolitioneers" which had carried over from the NCDUs and LtCdr Kauffmans recruiting them from the Seabee Dynamiting and Demolition school.
African American Service: the Seabee stevedores
In February 1942 CNO Admiral Harold Rainsford Stark recommended African Americans for ratings in the construction trades. In April the Navy announced it would enlist African Americans in the Seabees. Even so, there were just two regular CBs that were segregated units, the 34th and 80th NCBs. Both had white Southern officers and black enlisted. Both battalions experienced problems with that arrangement that led to the replacement of the officers.
The Navy had a huge need for cargo handlers. The lack of stevedores for unloading ships in combat zones was creating a problem. On 18 September 1942 authorization was granted for the formation of a different type of CB denoted by the tag "Special" for cargo handling. By wars end 41 Special Construction Battalions were commissioned of which 15 were segregated. Those Special CBs later became the first fully integrated units in the U.S. Navy. The wars end also brought the decommissioning of every one of those units. The Navy's contemporary version of these units are Navy Cargo Handling Battalions of the Navy Expeditionary Logistics Support Group (United States).
Of particular note were the actions of the 17th Special at Peleliu 15-18 September 1944 (Fig. 13). The Japanese mounted a counter-attack at 0200 hours on D-day night. By the time it was over nearly the entire 17th had volunteered to carry ammunition to the front lines, bring wounded back, fill where in where the wounded had been and man 37mm that had lost their crews. C Co 1st Battalion 7th Marines was hit hardest that night and was very much in need of the 17ths support. The 17th remained with the 7th Marines until the right flank had been secured D-plus 3. According to the Military History Encyclopedia on the Web, were it not for the "Black Marine shore party personal" the counterattack on the 7th Marines would not have been repulsed.
Seabee North Slope Oil Exploration 1944
A Construction Battalion Detachment (CBD) was formed from "screening Camp Peary and the NCF for geologists, petroleum engineers, driller (oil), tool pushers, roustabouts and roughnecks" and later designated 1058. The officers were chosen for their arctic experience with CB 12 and CB 66. Once chosen the detachment was assembled at Camp Lee Stephenson. The plan in 1944 had been to send them to the recaptured Oil fields of New Guinea with the assignment to get those fields back in production. This changed when Congress earmarked $1,000,000 for Operation Pet 4 and it was decided to send them to Alaska to determine if there was actually oil in NPR 4 (U.S. Navy Petroleum Reserve No. 4), an area that had been set aside in the oil reserve 20 years earlier. The area is known today as the National Petroleum Reserve in Alaska. The detachment's mission was to complete a detailed geologic study, begin core hole and deep well drilling, as well complete aerial and overland pipeline surveys. In 1944, a base camp was constructed a Point Barrow. During the summer of 1945 the Seabees drilled a 2000 foot wildcat designated Seabee 1 (wildcat wells) before being shut down by the cold. The well site was near 3 petroleum seepages in the Umiat area in the very south-east of NPR 4. The rock in the area was from the Upper Cretaceous and has been named the "Seabee Formation". In 1946 civilians took over for the Seabees some of whom had been members of CBD 1058 and were hired immediately upon discharge to continue in the same job they had performed for the Navy." The Navy drew upon the cold weather experience it learned from CBD 1058 and applied it in Operation Highjump and Operation Deep Freeze.
NCF made permanent USN component
"On 13 February 1945: Chief of Naval Operations Fleet Admiral Ernest J. King approved the retention of construction battalions as a permanent and integral part of the postwar Navy. When originally established in the Second World War, the Seabee organization was meant to be only a wartime expedient." By Wars end that expedient had grown to 325,000 men, roughly half the size of the Marine Corps 669,000.
When the Japanese signed the surrendered CB 114 was in the Aleutians. In September 1945 the battalion was ordered to send a detachment to the USSR to build a Naval Advance Base (a Fleet Weather Central). It was located 10 miles outside Petropavlovsk-Kamchatsky on the Kamchatka Peninsula and code named TAMA. The original agreement gave the Seabees 3 weeks to complete the camp. Upon arrival the Russians told the Seabees they had 10 days and were amazed that the Seabees did it. It was one of two that Stalin agreed to. The other was near Khabarousk, Siberia in buildings provided by the Russians. For mail Petropavlovsk was assigned Navy number 1169, FPO San Francisco.
With the fall of Japan Operation Beleaguer was initiated for the repatriation of thousands of displaced citizens in China as well as getting the remnants of the Japanese Army home. Part of the 33rd CB Regiment was involved; CBs 83, 96, 122 and 32nd Special. These units landed at Tsingtao and Tangku in November 1945 attached to the 6th Marine Division. CB 42 and A Co. 33rd Special landed at Shanghai TAD to Naval Advance Base Unit 13. With the war over, the discharge of all men eligible for discharge left only enough men for one CB and the two Specials. The men were consolidated in the 96thand the other units were decommissioned. In December the 96th started construction of airfields at Tsingtao and Chinwangtao to support III Marine Amphibious Corps operations. On 20 May 1946 orders were issued for CB III Marine Amphibious Corps to inactivate 96 CB on 1 August. Before that happened the 6th Marine Division was renamed the 3rd Marine Brigade which existed only until 10 June. At that time the 96th CB was transferred to the 4th Marines of the 1st Marine Division and were deactivated from them in August. An unknown CBMU was suppose to take over the maintenance of the airfields, but Operation Beleaguer was close to completing it's mission.
In early 1946 the 53rd NCB was still attached to III Marine Amphibious Corps and was deployed for the preparations of the nuclear testing at Bikini Atoll as a component of Operation Crossroads. At Bikini the battalion was assigned to Task Group 1.8 and designated TU 1.8.6. On 3 August the battalion was decommissioned with the men transferred to CBD 1156 that was commissioned on Bikini. The TU 1.8.6 designation continued with them. The Battalion remained on the atoll for nine days after the second nuclear test when it was detached from the Marine Corps and deactivated there.
UDT 3 was designated TU 1.1.3 for the operation. On 27 April 1946, 7 officers and 51 enlisted embarked the USS Begor(APD-127) at the Seabee's base, Port Hueneme, for transit to Bikini. Afterwards in 1948 the displaced natives put in a request to the U.S.Navy to blast a channel for access to the island Kili they had been relocated on. This was given to the Seabee detachment on Kwajelin who placed a request for UDT 3. The King of the Bikinians was so pleased he held a going-away feast for the UDTs.
In January 1947, CBs 104 and 105 were reactivated to join CB 103. The 121st CB was inactivated 31 December 1947 and re-designated CBD 1504. The Seabees were officially organized in the Naval Reserve during that month also. In June 1950 Seabee numbers stood at 2,800 active duty primarily due to the amphibious CBs. Between 1949 and 1968, Naval Construction Battalions were organized into two types of units: Amphibious Construction Battalions (ACBs) and Mobile Construction Battalions (MCBs).
The outbreak of the Korean War in June 1950 led to a call-up of more than 10,000 men from the Seabee Naval Reserve program. The Seabees landed at Inchon with the assault troops. They dealt with enormous tides and enemy fire while installing causeways within hours of the initial landings. Their action here and at other landings emphasized the role of the Seabees (Fig. 14). When the truce was declared there was no Seabee demobilization as there had been at the end of WWII.
During the Korean War, the Navy realized they needed a naval air station in this region. Cubi Point in the Philippines was selected, and civilian contractors were initially selected for the project. After seeing the forbidding Zambales Mountains and the maze of jungle, they claimed it could not be done. The Navy then turned to the Seabees. The first Seabees to arrive were Naval Mobile Construction Battalion Three (MCB 3) on 2 October 1951; followed by MCB 5 on 5 November 1951. Over the next five years, MCBs 2, 7, 9, 11 and 13 also deployed to Cubi Point. Seabees leveled a mountain to make way for a nearly two-mile-long runway. NAS Cubi Point turned out to be one of the largest earth-moving projects in the world, equivalent to the construction of the Panama Canal (Fig. 15). Seabees there moved 20 million cubic yards of dry fill plus another 15 million that was hydraulic fill. The $100 million facility was commissioned on 25 July 1956, and comprised an air station and an adjacent pier that was capable of docking the Navy's largest carriers. Adjusted for inflation, today's price-tag for what the Seabees built at Cubi Point would be $906,871,323.53. (that excludes the rest of the U.S.Naval Base at Subic Bay).
During the Korean War the Service School Command U.S.N.T.C. Great Lakes, Il. was the location of the U.S. Naval School Construction Battalion Reserve.
A product of the Cold War, Seabee Teams were an idea of the U.S. State Department for making "good use" of the Seabees. They could be sent as "U.S. Good Will Ambassadors" to third world nations as a means to combat the spread of Communism and promote "good Will", a military version of the Peace Corps. These 13 man teams would construct schools, drill wells or build clinics creating a positive image or rapport for the U.S. in the developing world. They were utilized by the United States Agency for International Development and were in S.E. Asia by the mid 1950s. Then in the early sixties the U.S.Army Special Forces were being sent into rural areas of South Vietnam to develop a self-defense force to counter the Communist threat and making use of the Seabee teams at these same places made perfect sense to the CIA. So twelve "Seabee teams with Secret Clearances were sent to Vietnam to assist the U.S. Army's Special Forces in the CIA funded Civilian Irregular Defense Group program (CIDG)" in the years 1963,64,65. By 1965 the U.S. Army had enough engineers in theater to end the Seabees involvement with the Special Forces At first they were called Seabee Technical Assistance Teams STAT. Teams after STAT 1104 were renamed Seabee Teams. In total 128 teams were sent to Vietnam with STAT 1104 being the most decorated group of Seabees ever. As a group the Seabee Teams received many awards for heroism. While Vietnam went on the teams were still being sent to other nations. The Royal Thai government requested STATs in 1963 and since then nearly every time a CB has left the United States for a deployment a Seabee team has been sent somewhere.
Construction Civic Action Details or CCAD
CCADs or "See-Kads" are larger civic action units of 20-25 Seabees with the same purpose as Seabee Teams (Fig. 16). The CCAD designation is not found in the record prior to 2013 and there is no explanation stating why these construction crews are called "details" and not "detachments".
On the 2nd and 5th of December 1946, 166 Seabees sailed from Port Hueneme on the USS Yancey and USS Merrick assigned to Operation Highjump. They were part of Admiral Richard E. Byrd's Antarctic expedition. The U.S.Navy was in charge with "Classified" orders "to do all it could to establish a basis for a (U.S.) land claim in Antarctica". The Navy sent the Seabees to do the job starting with the construction of Little America (exploration base) IV as well as a runway for aerial mapping flights. This Operation was vastly larger than IGY Operation Deep Freeze that followed.
In 1955, Seabees began deploying yearly to the continent of Antarctica as participants in Operation Deep Freeze. Their mission was to build and expand scientific bases located on the frozen continent and further establish a land claim for the U.S.(Fig. 19). The first "wintering over" party included 200 Seabees who distinguished themselves by constructing a 6,000-foot (1,800 m) ice runway on McMurdo Sound. Despite a blizzard that undid the entire project, the airstrip was completed in time for the advance party of Deep Freeze II to become the first to fly into the South Pole by plane. MCB 1 was assigned for Deep Freeze II.
Over the following years and under adverse conditions, Seabees added to their list of accomplishments such things as snow-compacted roads, underground storage, laboratories, and living areas. One of the most notable achievements took place in 1962, when MCB 1 constructed Antarctica's first nuclear power plant, which got them a Navy Unit Commendation. Another, in 1975, was the construction of the Buckminster Fuller Geodesic dome at Amundsen-Scott South Pole Station by NMCB 71. (Fig.18) with a diameter of 164 ft (50 m) and 52 ft (16 m) high. This became a symbolic icon of the United States Antarctic Program until it was replaced (Fig. 18).
During the Cold War, the Seabees undertook a number of other missions, including constructing the Distant Early Warning Line in the Arctic. Again operating often under extreme conditions, the Seabees successfully completed every mission assigned to them.
Seabees deployed to Vietnam twice in the 1950s. First in June 1954 as elements of Operation Passage to Freedom and then two years later to map and survey the nations roads. Seabee teams 501 and 502 arrived on 25 Jan 1963 and are regarded as the first Seabees of the Vietnam conflict. They were sent to Dam Pau and Tri Ton to build camps for the Special Forces. In June 1965, Construction Mechanic 3rd Class Marvin G. Shields was a member of Seabee Technical Assistance Team 1104, that took part in the Battle of Dong Xoai. He was posthumously awarded the Medal of Honor for his actions there and is the only Seabee ever to be awarded the Medal of Honor. Those Seabee "Civic Action Teams" continued throughout the Vietnam War and often were fending off enemy forces alongside their Marine and Army counterparts. Teams typically built schools, clinics or drilled wells. In 1964 ACB 1 was the first CB in the theatre. Beginning in 1965 Naval Construction Regiments (NCRs) deployed throughout Vietnam. The Seabees supported the Marines by building a staggering number of aircraft-support facilities, roads, and bridges. Seabees also worked with and taught construction skills to the Vietnamese people. In 1968 the Marine Corps requested that the Navy make a name change to the CBs. The Marines were using "MCB" for Marine Corps Base and the Navy was using "MCB" for Mobile Construction Battalions. The Navy then added "Naval" to MCB creating the NMCBs that now exist. In May 1968 two reserve battalions were activated (RNMCBs 12 and 22) which brought the total number of battalions rotating to Vietnam to 21 (not including ACBs 1 and 2 or the two Construction Battalion Maintenance Units (CBMUs) that were there too). During 1969 the total number of Seabees that had deployed topped out at 29,000 and then their draw-down began. The last battalion withdrew the end of 1971 which left 3 Seabee teams. They were out by at the end of 1972.
During the Vietnam conflict there were a couple of uniform variations of note. Across the back of the field jacket M-65 the unit number would be stenciled between the shoulders e.g. MCB 1. Another variation was the collar and cover devices for E4 - E6 enlisted (Fig. 21). The Navy authorized that the "crow" for the construction group be replaced by the rating insignia for each trade. These devices were made in gold and black (subdued).
Seabees were first assigned to the State Department in 1964 because listening devices were found in the Embassy of the United States in Moscow. The U.S. had just constructed a new embassy in Warsaw and Seabees were dispatched to check that one out and found lots of "bugs". This led to the creation of the support unit in 1966. There are a limited number of special billets for select senior NCOs, E-5 and above. These Seabees are assigned to the Department of State and attached to Diplomatic Security. Those chosen can be assigned individually or be part of a regional team traveling from one embassy to the next. Duties include the installation of alarm systems, CCTV cameras, electromagnetic locks, safes, vehicle barriers, and securing compounds(Fig. 22). They can also assist with the security engineering in sweeping embassies (electronic counter-intelligence). They are tasked with new construction or renovations in security sensitive areas and supervise private contractors in non-sensitive areas. Due to Diplomatic protocol the Support Unit is required to wear civilian clothes most of the time they are on duty and receive a supplemental clothing allowance for this. The information regarding this assignment is very scant, but State Department records in 1985 indicate Department security had 800 employees, plus 1,200 Marines and 115 Seabees. That Seabee number is roughly the same today.
On 28 January 1969 a detachment of 50 men from Amphibious Construction Battalion 2 augmented by an additional 17 Seabee divers from both the Atlantic and Pacific fleets as well as the 21st NCR began the installation of the Tektite habitat in Great Lameshur Bay at Lameshur, U.S. Virgin Islands. The Tektite program was funded by NASA and was the first scientists-in-the-sea program sponsored by the U.S. government.(Fig. 23). The Seabees also constructed a 12-hut base camp at Viers that is used today as the Virgin Islands Environmental Resource Station. The Tektite project was a product of the Cold War and caused the U.S. Navy to realize it needed a permanent Underwater Construction capability. "It was this project that led to the formation the Seabee Underwater Construction Teams".
As the Cold War wound down, new challenges were presented by the increased incidence of terrorism. There were also ongoing support missions to Diego Garcia, Guam, Okinawa, Navy and Marine Bases in Japan, the Philippines, Puerto Rico, Guantanamo Bay, Guatemala, the Naval Support Facility for Polaris and Poseidon submarines in Holy Loch, Scotland, Rota, Spain, Naples, Italy, and Souda Bay, Crete. In 1971, the Seabees began their second huge peacetime construction on Diego Garcia, a small atoll in the Indian Ocean. This project began in 1971 and was completed in 1987 at a cost of $200 million. Because of the extended time-frame, it is difficult to inflation-adjust that cost into today's dollars. The complex accommodates the Navy's largest ships and cargo planes. This base proved invaluable when Iraq invaded Kuwait in August 1990 and Operations Desert Shield and Desert Storm were launched.
There were combat roles as well. In 1983, a truck bomb demolished the barracks the Marines had secured in Beirut, Lebanon. After moving to the Beirut International Airport and setting up quarters there, Druse militia artillery began harassing the Marines. After consultations with the theater commander, Marine amphibious command and combat engineers, the forward-deployed battalion, NMCB-1 in Rota, Spain, sent in a 70-man AirDet working party with heavy equipment. Construction of artillery-resistant quarters went on from December 1983 until the Marines' withdrawal in February 1984. Only one casualty occurred when an equipment operator using a bulldozer to clear fields of fire was wounded by an RPG attack. Seabee EO2 Kirt May received the first Purple Heart awarded to a Seabee since Vietnam.
Robert Stethem was murdered by the Lebanese Shia militia Hezbollah when they hijacked TWA Flight 847 in 1985. Stethem was a Steelworker Second Class (SW2), a Seabee diver and member of Underwater Construction Team One. The USS Stethem (DDG-63) is named in his honor. On 24 August 2010, on board USS Stethem in Yokosuka, Kanagawa, Japan, Stethem was posthumously made an honorary Master Chief Constructionman (CUCM) by the Master Chief Petty Officer of the Navy and awarded the Prisoner of War Medal.
During the Persian Gulf War, more than 5,000 Seabees (4,000 active and 1,000 reservists) served in the Middle East. In Saudi Arabia, Seabees built ten camps for more than 42,000 personnel; fourteen galleys capable of feeding 75,000 people; and 6 million ft² (600,000 m²) of aircraft parking apron and runways as well as over 200 helicopter landing zones. They built and maintained two 500-bed Fleet Hospitals near the port city of Al-Jubayl. Initially deployed was Battalion 7 from deployment at Camp Shields, Okinawa in September 1990. In November, battalion 74 from homeport rotation at Gulfport, Mississippi replaced NMCB7 at their interim deployment site on the island of Bahrain.
In December 1990 NMCB74 moved entirely from Bahrain, crossing by causeway to Saudi Arabia and turned North along the coast for approximately 300 kilometers. A desert camp was constructed at Ras Al Mishab, near the Kuwaiti border, and named "Camp Nomad". It was from this camp NMCB74 based its operations. One 'client' of this battalion's services was Marine Air Group 26. Many other clients enjoyed services.
NMCB74 was involved in Operation Troy, a deceptive maneuver intended to assure the Iraqi's the American main thrust would be from the Southern Kuwaiti border. NMCB74's internal name for it's participating element was "Detachment Black". Det Black constructed mock tanks, tube artillery, and manned these mock emplacements.
RNMCB24, a reserve battalion, was based at Al Jubail industrial city. This battalion served units in its area and provided rear echelon support for forward deployed NMCB74 at Mishab. Regular supply runs linked the two battalions along the MSR which ran north/south along the coast.
Seabees continue to provide critical construction skills in connection with the effort to rebuild the infrastructure of Afghanistan. All active and reserve Naval Mobile Construction Battalions (NMCBs) and Naval Construction Regiments (NCRs) have been deployed to both Iraq and Afghanistan. The Seabees have been deployed since the beginning of the invasion of Afghanistan in 2001 and Iraq in 2003. One of their most high-profile tasks in Iraq has been the removal of statues of Saddam Hussein in Baghdad. In Afghanistan, the Seabees' main task has been the construction of multiple forward operating bases for U.S. and coalition forces.
Since 2002, Seabees have provided critical and tactical construction skills in an effort to win the hearts and minds of locals in the Philippines. Their efforts have begun to deter the rising influence of radical terrorists in the southern Philippines, most notably the Abu Sayyaf's jungle training area. Seabees work along with Army, Marines, and Air Force under Joint Special Operations Task Force-Philippines.
On 1 March 1942 the Chief of BuDocks recommended that as a means to promote esprit de corps in the new branch of construction battalions, that an insignia be created for use on equipment similar to what air squadrons used on their aircraft(Fig. 26). This was not something for the uniform.:136 Frank J. Iafrate, a civilian plan file clerk at Quonset Point Advance Naval Base, Davisville, Rhode Island, was the artist who designed the original "Disney Style" Seabee in early 1942 with a large capital letter Q around the edge as border. This design was sent to Admiral Moreell who made a single request: that this reference to Quonset Point be changed to a hawser rope and it would be officially adopted. That design remains in use to this day, predominantly unchanged. In late 1942, after designing the logo, Iafrate enlisted in the Seabees. The Camp Post exchanges (PXs) sold pennants with a different Seabee design on them, that was stylistically similar to the Mosquito boat rating insignia.
The Seabees also had a second Logo that much less has been written about(Fig. 9). It was that of a shirtless construction worker holding a sledge hammer with a rifle strapped across his back standing upon the words "Construimus Batuimus USN". The figure is typically on a shield with a blue field across the top and vertical red and white stripes. A small CEC logo is left of the figure and a small anchor is to the right. The Camp's PXs sold two versions of brass badges with this logo, enameled or non-enameled. Despite little being written about this logo it is incorporated into many CB Unit insignias (or variations of it). A partial list of these CBs would be: 9, 15, 17, 23, 29, 41, 45, 50, 68, 75, 77, 86, 87, 90, 93, 95, 99, 145 & 18th Special, Construction Battalion Units (CBUs) 408, 504, 535 and the 7th Brigade. Other units simply used it like 133 NCB did on the front cover of their unit history the "Rain Makers Log".
During World War II, artists working for Walt Disney in the Insignia Department designed logos for about ten Naval Construction units, including the 60th NCB, the 78th NCB the 112th NCB and the 133rd NCB Good candidates, though unknown, are the logos of the 1st NCB, 53rd NCB, 615th CBMU, 30th Regiment and the 6th Brigade There are two Seabee logos in the book on WWII Disney insignia entitled "Disney Don's Dogtags" that are not identified with any unit. Disney did not create the original Seabee insignia.
The end of WWII brought the decommissioning of nearly every Seabee Battalion. The Construction Battalions had been in existence less than four years when this happened and the Navy had not created a Historical Branch or Archive for the NCF. So, there was no central record of the Seabees History or archive for the insignia of the individual units. As history passed, first with Korea and them Vietnam, Construction Battalions were reactivated with the units having no idea what the WWII insignia had been so they made new ones, NMCB One has had three. NMCB 8 is the exception. That Battalion has an insignia very similar to what it had during WWII.
A small number of Seabees support Navy Special Warfare (NSW) units based out of Coronado, CA, and Virginia Beach, VA. Seabees provide services such as power generation/distribution, logistical movement, vehicle repair, construction and maintenance of encampments, water facilities and purification. Seabees assigned to support NSW receive extra training in first aid, small arms, driving, and specialized equipment. The Seabees assigned to NSW are expected to qualify as Expeditionary Warfare Specialists. If desired or required by the unit, Seabees assigned to NSW are eligible to receive the following Naval Enlisted Classifications upon filling the requirements: 5306 - Naval Special Warfare (Combat Service Support) or 5307 - Naval Special Warfare (Combat Support). They also can apply for selection to support the NSW Development Group.
The battalion is the fundamental unit of the Naval Construction Force (NCF). Seabee battalions are constituted in such a way as to be self-sustaining in the field. The nomenclature for NCF battalions has evolved over the years. During World War II, there were more than 140 battalions commissioned(fig. 27). Since then, battalions have been activated and deactivated using WWII unit numbers. Detachment: This is a construction crew that is sent to smaller construction projects "detached" from the main body's deployment site. They tend to be self-contained construction units capable of independently completing the assigned project.
From the early 1960s through 1991, reserve battalions were designated as Reserve Naval Mobile Construction Battalions (RNMCBs). After 1991, the word "reserve" was dropped, signifying the integration of reserve units with the active units of the NCF.
During the rapid build-up of the Seabees during World War II, the number of battalions in a given area increased and larger construction programs were undertaken.
This necessitated a higher command echelon to plan, coordinate, and assign the work of several battalions in one area. As a result, Naval Construction Regiments (NCRs) were established in December 1942.:136
Brigades were the highest NCF command echelon, until early in the 21st Century. At that time, the last two brigades were the Second Naval Construction Brigade (2nd NCB) and the Third Naval Construction Brigade (3rd NCB). The 2nd NCB commanded Atlantic Fleet Seabee units and the 3rd NCB commanded Pacific Fleet Seabee units.
Both brigades were decommissioned in August 2002 and are no longer part of the NCF structure.
Shortly after the commencement of the Global War on Terror, it was realized that a single command interface for global Seabee operations would be required. On August 9, 2002, the First Naval Construction Division (1NCD) was stood-up and commissioned at NAB Little Creek in Virginia.
Since January 2006, 1NCD has been a subordinate unit of Navy Expeditionary Combat Command (NECC). First Naval Construction Division (1NCD) was decommissioned May 31, 2013. The 1NCD staff will be integrated into NECC. Some 1NCD functions have been transferred to the newly created Naval Construction Groups (NCGs) in Gulfport, Mississippi, and Port Hueneme, California, which are now the East and West Coast community for the NCF.
When first organized during World War II, these units consisted of approximately one fourth of the personnel of an NCB, and were intended to take over the maintenance of bases on which major construction had been completed.
Today, CBMU's provide public works support at Naval Support Activities, Forward Operating Bases, and Fleet Hospital/Expeditionary Medical Facilities during wartime or contingency operations. They also provide disaster recovery support to Naval Regional Commanders in CONUS.
UCTs deploy worldwide to conduct underwater construction, inspection, repair, and demolition operations of ocean facilities, to include repair of battle damage. They maintain a capability to support a Fleet Marine Force amphibious assault, subsequent combat service support ashore, and self-defense for their camp and facilities under construction.
UCT1 is home ported at Virginia Beach, Virginia, while UCT2 is at Port Hueneme, California.
In 2013, the Seabee Readiness Groups (SRGs) were decommissioned, and re-formed into Naval Construction Groups One and Two. They are regimental-level command groups, tasked with administrative and tactical control of Seabee Battalions, as well as conducting pre-deployment training of NCF units in the NCGs' respective home port locations. Currently, Naval Construction Group Two (NCG-2) is based at CBC Gulfport, and Naval Construction Group One (NCG-1) is based at CBC Port Hueneme.
ACBs (also abbreviated as PHIBCB) evolved out of pontoon assembly battalions formed as part of the Seabees during World War II. On 31 October 1950, MCBs 104 and 105 were re-designated ACB One and ACB Two, and assigned to Naval Beach Groups.
Today, the ACBs are not part of the NCF, reporting to surface TYCOMs. Additionally, an ACB has a different personnel-mix to an NMCB, with half the enlisted personnel being traditional Seabee rates and the other half being fleet rates.
These units have CEC officers leading them and enlisted Seabees for the various crews. About one-third of new Seabees are assigned to Public Works Departments (PWD) at naval installations both within the United States and overseas. While stationed at a Public Works Department, a Seabee has the opportunity to get specialized training and extensive experience in one or more facets of their rating.
Some bases have civilians that augment the Seabees, but the department is a military organization.
Seabee Engineer Reconnaissance Teams are ten-person teams, developed during Operation Iraqi Freedom (Fig.29). SERTs are divided into three components: a liaison element, a security element and a reconnaissance element. The liaison (LNO) element has a CEC officer and two petty officers who are communications specialists. The LNO element is responsible for communications with higher echelons, both in transferring engineering assessments and intelligence and in receiving engineering reach-back solutions. The reconnaissance element has a CEC officer, who is the SERT Officer-in-Charge (OIC), a Builder or Steelworker chief petty officer who has some bridge construction experience, and petty officers of varying Seabee ratings. The OIC is normally a licensed professional engineer with a civil/structural engineering background.
A SERT unit will include a corpsman or corpsman-trained member, with the rest of the team being selected from the best of their trades in their battalion. All are qualified Seabee Combat Warfare Specialists. The UCTs proved the SERT concept was viable and they have led the way to the concept's adoption throughout OIF.
The newcomers begin "A" School (preliminary training) fresh out of boot camp, or they come from the fleet after their service term is met, spending about 75% of the twelve weeks immersed in hands-on training. The remaining 25% is spent in classroom instruction. From "A" School, new Seabees most often report to an NMCB command for their first tour of duty. For training, the new Seabees attend a four-week course of Expeditionary Combat Skills (ECS) at the Naval Construction Battalion Center in Gulfport, Mississippi, and Port Hueneme, California. ECS is also being taught to all personnel who report to a unit in the Navy Expeditionary Combat Command. ECS is a basic combat-skills course in learning map reading and land navigation, battlefield first aid, formulating defensive plans, conducting reconnaissance, and other combat-related skills. Half of each course is spent at a shooting range learning basic rifle-marksmanship and qualifying with a M16A2 or M16A3 rifle and the M9 service pistol. Those that are posted Alfa Co[clarification needed] of an NMCB may be assigned to a crew-served weapon, such as the MK 19 40 mm grenade launcher, the M2HB .50-caliber machine gun, or the M240 machine gun. Many reserve units still field variants of the M60 machine gun. Until 2012, Seabees wore the U.S. Woodland camouflage uniform or the legacy tri-color Desert Camouflage Uniform, the last members of the entire U.S. military to do so, but have now transitioned to the Navy Working Uniform NWU Type III. Seabees use ALICE field gear, as well as some units working with Marines using USMC-issue Improved Load Bearing Equipment (ILBE) gear.
Camp Endicott had roughly 45 different vocational schools plus additional specialized classes. These included Air compressors, Arc welding, BAR, Bridge building, Bulldozer operation, Camouflage, Carpentry, Concrete construction, Crane operation, Dam building, Diving, Diesel engines, Distillation and water purification, Dock building, Drafting, Drilling, Dry docks, Dynamite and demolition, Electricity, Electric motors, First aid, Fire fighting, Gasoline Engines, Generators, Grading roads and airfields, Ice makers, Ignition systems, Judo, Hut and tents, Lubrication, Machine gun, Marine engines, Marston Matting, Mosquito control, Photography, Pile driving, Pipe-fitting/plumbing, Pontoons, Power-shovel operation, Pumps, Radio, Refrigeration, Rifle, Riveting, Road building, Road Scrapers, Sheet metal, Soil testing, Steelworking, Storage tanks wood or steel, Tire repair, Tractor operation, Transformers, Vulcanizing, Water front, and Well-drilling.
WWII These indicate the construction trade in which a Seabee is skilled. During WWII, the Seabees were the highest-paid component in the U.S. Military, due to all the skilled journeymen in their ranks.
DIVER: During WWII being a Navy diver (United States Navy) was not a "rate" it was a "qualification" that had four grades: Master, 1st Class, Salvage, and 2nd Class. The Seabee diving schools could only qualify divers 2nd class . Numerous CBs had men qualified, 21st CB 27th CB, and the 34th CB (segregated) to name a few .
Diver : is a qualification that the various rates can obtain with three grades: Basic Underwater Construction Technician/ NEC 5932 (2nd Class Diver), Advanced Underwater Construction Technician/ NEC 5931 (1st Class Diver), and Master Underwater Construction Technician/ NEC 5933 (Master diver).
The Seabee ranks of E-1 through E-3 use the designation "Constructionman" and wear sky-blue stripes on their dress and service uniforms. This blue was adopted in 1899 as a uniform trim color designating the Civil Engineer Corps, but was later given up. Its use by the junior enlisted is a bit of Naval Heritage in the NCF.
At E9 the ratings are reduced to three: EQCM for equipment operators and construction mechanics, CUCM for builders, steelworkers and engineering aids, UCCM for construction electricians and utilitiesmen.
The military qualification badge for the Seabees is known as the Seabee combat warfare specialist insignia (SCW)(Fig. 34). It was created in 1993 for issue to both officers and enlisted personnel that fulfill the training requirements. Only members attached to a qualifying NCF unit are eligible for the SCW pin. The qualifying units include: Naval Mobile Construction Battalions (NMCB), Amphibious Construction Battalions (ACB), Naval Construction Force Support Units (NCFSU), Underwater Construction Teams (UCT), and, since the end of 2008, Naval Construction Regiments (NCR).
The Fleet Marine Force Insignia(Fig. 35), also known as the Fleet Marine Force pin or FMF pin, are three military badges of the United States Navy which are issued to those U.S. Navy officers and sailors who are trained and qualified to perform duties in support of the United States Marine Corps. Those Seabees that draw an assignment with the Fleet Marine Force can earn the Fleet Marine Force Insignia, also known as the Fleet Marine Force pin or FMF pin. the United States Navy has authorized these badges for U.S. Navy officers and sailors who are trained and qualified to perform duties in support of the United States Marine Corps. There are currently three classes of the Fleet Marine Force pin: enlisted, officer, and chaplain. For the requirements, see: Fleet Marine Force Warfare Specialist (EFMFWS) Program per OPNAV Instruction 1414.4B.
The Peltier Award is given to the "best of type" active duty Naval Construction Battalions. It was instituted by Rear Admiral Eugene J. Peltier CEC and has been given annually since 1960. He is a former head of the Bureau of Yards and Docks (1959-1962).
At present, there are six active-duty Naval Mobile Construction Battalions (NMCBs) in the United States Navy, split between the Pacific Fleet (Port Hueneme, CA) and the Atlantic Fleet (Gulfport, MS).

The first ship of a series of six "Sea Bee" ships, was the SS Cape Mendocino (T-AKR-5064), followed by SS Cape May (T-AKR-5063) and SS Cape Mohican (T-AKR-5065)(Fig. 37), three of which were operated by Lykes Brothers Steamship Company. "The U.S. Navy's Naval Construction Force, or SeaBees, primarily use the SEABEE barges. The barges are loaded with cargo and floated to and from a mother ship, which allows loading and unloading of containerized cargo off-shore. SEABEE barge ships are equipped with a stern cargo elevator for loading the barges from the water onto the vessel; loaded barges can then be moved toward the vessel's bow using an internal track system. The barges are stowed on internal decks and are not stacked. The "Sea Bee" vessels had three decks and could transport 38 lighters (12 on the lower decks and 14 on the upper deck). SEABEE barges are larger and heavier than their counterpart, LASH barges." The dual function of the ship is noteworthy, as it had storage tanks with a capacity of nearly 36000 m³ volume built into its sides and unusually large double hull, allowing it to be used also as a product tanker. The ships were later purchased by Military Sealift Command.
The U.S. Navy Seabee Museum is located at Naval Base Ventura County, Port Hueneme, California near the entrance, but outside the main gate. Due to the location, visitors are able to visit the museum without having to enter the base proper. The museum re-opened on 22 July 2011 in a new building built by Carlsbad-based RQ Construction. The design of the single-story, 38,833 square foot structure was inspired by the Seabee Quonset hut. Inside are galleries for exhibition space, a grand hall, a theater for 45 people, collections storage, and research areas.
On 7 February 2011, the museum was certified as LEED Silver for utilizing a number of sustainable design and construction strategies. Features include the use of low-maintenance landscaping; a "cool" roofing system with high solar reflectance and thermal emittance; use of photocell-controlled light fixtures and energy-efficient lighting fixtures; 30% use of regional materials and 80% construction debris was recycled and diverted from landfills; low-volatility organic compounds (VOCs); and, use of dual-flush toilets and low-flow aerator faucets.
The Seabee Heritage Center is located in Building 446 at the Naval Construction Battalion Center. The Heritage Center is the Atlantic Coast Annex of the Seabee Museum in Port Hueneme. Opened in 1995, the museum annex commemorates the history and achievements of the Atlantic Coast Naval Construction Force (Seabees) and the Navy's Civil Engineer Corps. Exhibits at the Gulfport Annex are provided by the Seabee Museum in Port Hueneme.
