About this Unit
The Marine Detachment (MARDET) aboard USS New Jersey (BB-62) served as the ship’s security force, ceremonial unit, and provided gun crews during her active service periods. Established with the ship’s initial commissioning in 1943, the MARDET participated in major World War II Pacific operations, including the battles of the Philippine Sea and Okinawa. Marines from the detachment contributed to shipboard defense and manned secondary batteries during combat. The MARDET continued its service through the Korean War, Vietnam War, and later deployments until the phasing out of shipboard Marine detachments in the late 20th century.
