Assault Craft Unit 1 traces its roots to World War II as hundreds of LCUs were decommissioned, leaving 30 LCUs in the command of "Centralized Flotilla Command" in NAB Coronado known as LCU Squadron ONE. In July, 1947, a neighboring command, Boat Unit ONE, was created to command Landing Craft Mechanized (LCM) LCM-3s and Landing Craft, Vehicle, Personnel (LCVP)s. In 1950, the two commands participated in the Battle of Inchon and in every amphibious operation of the Korean War afterward.
