À la fin de la Seconde Guerre mondiale, les UDT furent massivement démobilisées, mais celles restantes se livrèrent à de nombreuses expérimentations, dont les opérations type raid commando pour détruire un objectif à l'intérieur des terres, les opérations sous-marines (nageurs de combat), et l'utilisation de la troisième dimension (expérimentation de l'emploi de l'hélicoptère et du système Fulton).

The UDT also began developing weapons skills and procedures for commando operations on land in coastal regions. The NCDU members (designated Demolitions Gap-Assault teams comprised of Army Combat Engineers and Navy Combat Demolition personnel, on Omaha, with a counterpart, Beach Obstacle Demolition Parties on Utah) would come in with the second wave and work at low tide to clear the obstacles.

In August 1941, landing trials were performed and one hazardous operation led Second Lieutenant Lloyd E.

During the Korean War, the UDTs operated on the coasts of North Korea, with their efforts initially focused on demolitions and mine disposal. After Kwajalein, the UDT created the Naval Combat Demolition Training and Experimental Base at Kihei, next to the Amphibious Base at Kamaole on Maui.
