About this Unit
**Mardet USS Wasp (CV-18)** refers to the Marine Detachment assigned to the aircraft carrier USS Wasp (CV-18), an Essex-class carrier commissioned in 1943. Throughout World War II, the Mardet served as shipboard security, manned anti-aircraft guns, and provided ceremonial duties, supporting the carrier’s operations during major Pacific campaigns. The Marines played a crucial role during kamikaze attacks and in maintaining order aboard ship during intense combat operations. After World War II, the detachment continued to serve until the gradual phase-out of Marine Detachments on carriers in the late 20th century.
