Marine Detachment USS Constellation (CVA-64)

• Commissioned Detachment: The Marine Detachment (MARDET) aboard USS Constellation (CVA-64) was activated when the ship entered service in 1961, serving as an integral part of the ship’s company. • Security Role: Marines were responsible for the security of the ship, including guarding nuclear weapons and providing a quick reaction force in case of emergencies such as sabotage or mutiny. • Vietnam War Service: The MARDET participated in multiple deployments to the Gulf of Tonkin during the Vietnam War, supporting combat operations and maintaining shipboard security. • Ceremonial Duties: In addition to security, the Marines performed ceremonial functions, including manning the rails during port visits and official ceremonies, acting as honor guards. • Brig Operations: The Marine Detachment managed the ship’s brig (jail), handling prisoners and maintaining discipline for the crew of over 5,000 sailors and airmen. • Small Arms Proficiency: Marines regularly drilled in small arms and close-quarters combat, often conducting live-fire exercises on the flight deck or at foreign ports. • Disbandment Era: The MARDET was a visible part of the ship until the late 1990s, when most shipboard Marine detachments were deactivated as their roles were absorbed by naval security forces. • Cross-training: Marines frequently cross-trained with Navy personnel in firefighting, damage control, and rescue operations, reflecting the joint nature of aircraft carrier missions. • Liberty Incident Stories: Marines were often involved in “Shore Patrol” during port visits, helping keep order among the crew on liberty—sometimes leading to legendary (and humorous) sea stories. • Legacy and Reunions: Former MARDET members of Constellation maintain a strong veterans’ network, attending reunions and preserving the detachment’s unique history within both the Marine Corps and Navy.
