Marine Detachment USS Philippine Sea (CV-47)

• Commissioning and Role: The Marine Detachment (MarDet) aboard USS Philippine Sea (CV-47) was activated in 1946, serving as an integral security and ceremonial unit aboard the aircraft carrier. Marine Detachments provided shipboard security, manned secondary batteries, and performed boarding and landing party duties. • Korean War Service: The MarDet participated in the Korean War (1950-1953), notably supporting Task Force 77’s air strikes. Their responsibilities included shipboard defense during hazardous wartime operations off the Korean peninsula. • Hangar Bay Guards: Marines of the detachment were often posted as sentries in the hangar bay, safeguarding the carrier's vital aircraft and sensitive areas, especially during periods of high alert or while in foreign ports. • Battle Stations: During General Quarters, the Marine Detachment manned 20mm and 40mm anti-aircraft guns, reflecting their dual function as both security and combat personnel aboard the ship. • Cross-Training: Marines on the Philippine Sea regularly cross-trained with Navy personnel in damage control, firefighting, and NBC (nuclear, biological, chemical) defense, showcasing the multi-role versatility of MarDet units. • Shipboard Ceremonies: The MarDet provided color guards and rifle squads for ceremonies at sea and in port, including visits from dignitaries, burials at sea, and change-of-command events, upholding naval traditions. • Prisoner Handling: During Korean War operations, the Marine Detachment was tasked with detaining and guarding prisoners of war temporarily held on board before transfer ashore. • Unusual Rescue Mission: In 1948, Marines participated in an at-sea rescue of crew from a crashed carrier-based aircraft, demonstrating adaptability beyond their traditional duties. • Final Decommissioning: USS Philippine Sea was decommissioned in 1958. The disbandment of its Marine Detachment reflected the broader post-Korean War reduction and eventual elimination of MarDets from aircraft carriers by the 1970s. • Legacy and Honors: Veterans of the MarDet on USS Philippine Sea contributed to the ship earning two battle stars for Korean War service, cementing their place in Marine Corps and naval history.
