About this Unit
**MarDet USS Essex (CVS-9)** refers to the Marine Detachment assigned to the aircraft carrier USS Essex (CVS-9), an Essex-class carrier commissioned in 1942. Throughout World War II, the MarDet provided shipboard security, manned secondary armament, and supported amphibious operations in the Pacific. During the Korean War and the early years of the Cold War, the detachment continued its security and ceremonial duties as Essex was modernized for anti-submarine warfare. The MarDet was disbanded in the early 1970s as the Navy phased out Marine detachments on board its ships.
