About this Unit
The Marine Detachment aboard USS Philippine Sea (CV-47) was activated when the Essex-class aircraft carrier was commissioned in May 1946. As with other carrier-based Marine Detachments of the era, its primary roles included ship security, ceremonial duties, and the operation of the ship’s brig. During the Korean War, the Marine Detachment supported air operations and contributed to shipboard defense while the Philippine Sea launched air strikes in support of United Nations forces. The unit remained active throughout the ship’s deployments until the carrier’s decommissioning in 1958, exemplifying Marine Corps discipline and tradition afloat.
