During the 1960's, Seabee divers became major contributors to the early success of the "Man-in-the-Sea" programs, including SEALAB II and TEKTITE II undersea laboratories. In 1969, it became evident there was need for a dedicated unit on each coast to support Fleet Underwater Construction. In 1974, the two detachments of Seabee divers were commissioned as Underwater Construction Teams with a Civil Engineer Corps Officer as the Officer in Charge. In 1985, the Underwater Construction Teams were elevated to Command status. UCT ONE is currently homeported in Little Creek, Virginia and UCT TWO in Port Hueneme, California.

The UCTs have a Shore Duty component and a Sea Duty component. Sea Duty personnel are divided into three Air Detachments that deploy worldwide to conduct underwater construction, inspection, repair, and demolition operations in support of both peacetime and wartime missions. The Shore Duty component contains all of the staff and support functions such as Administration, Supply, Logistics, Table of Allowance Maintenance, and Training. UCTs execute underwater construction tasking in both permissive and non-permissive environments as well as in climates ranging from the Tropics to extreme cold weather.
