HMM-164

Marine Medium Helicopter Squadron 164 (HMM-164), also known as the "Knightriders," was activated on July 1, 1964, at Marine Corps Air Facility Santa Ana, California. The squadron quickly deployed to Vietnam, where it played a vital role in troop transport, medevac, and resupply missions using CH-46 Sea Knight helicopters. HMM-164 participated in major operations throughout the Vietnam War, earning multiple unit commendations for its distinguished service. Following Vietnam, the squadron continued to support Marine Corps operations worldwide until it was redesignated as VMM-164 in 2015, transitioning to the MV-22 Osprey tiltrotor aircraft.
