Today the Seabees have many special task assignments starting with Camp David and the Naval Support Unit at the Department of State.

The toolbox was expanded to include underwater construction,[16] demolition, as well as the related combat applications used by the Seabees that comprised the NCDU's and UDTs.

[38] They built everything: airfields, airstrips, piers, wharves, breakwaters, PT & seaplane bases, bridges, roads, com-centers, fuel farms, hospitals, barracks and anything else.

[43] In May 1943 he completed CEC training at Camp Endicott and was posted as the Public Works officer at Manana barracks Hawaii Territory.

[56]Construction Battalion Detachment (CBD) 1058 was formed from "screening Camp Peary and the NCF for geologists, petroleum engineers, oil drillers, tool pushers, roustabouts and roughnecks" and later designated 1058.

The detachment's mission was: On July 19 the USS Spica headed north with the SS Jonathan Harrington for Point Barrow and Cape Simpson.

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".

Upon leaving boot the recruits were sent to National Youth Administration camps in Illinois, New Jersey, New York, and Virginia to receive military training from the Marine Corps.

Admiral Moreell wrote, tongue in cheek, that the Marines were the best fighting men in the Pacific, but one had to serve 90 days with the Seabees to qualify to as a "Junior Bee".

Six Officers led by Lt. Fred Wise CEC and eighteen enlisted reported from Camp Peary dynamiting and demolition school.

The MU men brought with the swimfins they had trained with and the Seabees made them a part of UDT attire as quickly as the Supply dept.

[127] In the Seabee dominated teams the next largest group of UDT volunteers came from the joint Army-Navy Scouts and Raiders school that was also in Fort Pierce.

Seabee service during this period supported a broad spectrum of the national interest; nuclear testing, two wars, embassy security, space race, CIA, military communications, international relations, pure science, and Camp David.

[143] 53's project list included observation, instrument and communication towers, radio beacons, seismic huts, photo reference crosses, general base and recreational facilities, as well as dredging the lagoon.

The $100 million facility ($1.1 billion in 2023 dollars) 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.

To start, twelve "Seabee teams, with Secret Clearances, were sent with the Army's Special Forces in the CIA funded Civilian Irregular Defense Group program (CIDG)"[155][156] in the years 1963–1965.

"In the early 1950s, Seabee BUs, UTs and CEs took over routine maintenance of the base and additional rates were added for administrative functions.

"[161] "Selectees undergo a single scope background investigation to determine if they qualify for a Top Secret Sensitive Yankee White (YW) clearance.

[162] 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.

Seabee Teams were part of a propaganda program to promote support for the RVN through positive community engagement, typically building schools, clinics, or drilling wells.

[199][200] That year William Darrah, a Seabee of the support unit, is credited with saving the U.S. Embassy in Prague, Czechoslovakia from a potentially disastrous fire.

Duties include the installation of alarm systems, CCTV cameras, electromagnetic locks, safes, vehicle barriers, and securing compounds.

Additionally, Seabees were also tasked upgrading and expanding Naval Air Station Sigonella, Sicily for the United States Sixth Fleet.

[209] In Saudi Arabia, Seabees built numerous camps, galleys, runways, aprons, helo zones, plus two 500-bed Fleet Hospitals near Al-Jubayl.

They are regimental-level command groups tasked with administrative and operational control of CBs, as well as conducting pre deployment training for all assigned units.

[221] The training qualifies divers as Underwater Construction Technicians skilled in: seafloor excavation, hydrographic surveys, search and recovery, engineering reconnaissance, and precision demolitions.

[224][225] The assignment requires additional training in first aid, small arms, driving, specialized equipment, and[224][225] qualifying as Expeditionary Warfare Specialists.

[1]: 136  Frank J. Iafrate, a civilian file clerk at Quonset Point Advance Naval Base, Davisville, Rhode Island, who created the original "Disney Style" Seabee.

In early 1942 his design was sent to RADM Moreell who made a single request: that the Seabee being set inside a letter Q, for Quonset Point, be changed to a hawser rope and it would be officially adopted.

The U.S. Navy Seabee Museum[241] is located outside the main gate of Naval Base Ventura County in Port Hueneme, California.
