From then on, UDT and NCDU training focused on swimming and operating without lifelines.
Under the leadership of retired SEAL Captain Norman Olson, the museum was established on the old NCDU training school grounds and dedicated on Veteran's Day 1985.
On this ground, volunteers trained to become members of the Naval Combat Demolition Units (NCDUs) and Underwater Demolition Teams (UDTs) of World War II.
Combined into gap assault teams to clear beach and underwater obstacles in the landings at Normandy in June 1944, Army combat engineers and naval combat demolition units (NCDUs) experienced D-Day like everyone else--terrified beyond measure.
King, Chief of Naval Operations (CNO), formally announced a plan to establish a program to train NCDUs. With no reference to the Army's efforts, the CNO said simply that it made sense to prepare for the eventuality of having to achieve passage through underwater obstacles on enemy beaches--basically, the Navy thought it was a good idea.
At Fort Pierce, the 299th learned techniques from the NCDUs, demonstrated there in February 1944.
