History 

Marine Medium Helicopter 774 was activated 5. September 1958, at NAS New York as Marine Transport Helicopter Squadron 774. The squadron operated the SH-34G/J Sea Bat helicopter. In April 1962 the squadron was redesignated Marine Medium Helicopter Squadron 774, but was deactivated on 30. September 1962.

HMM-774 was reactivated at NAS Norfolk on 1. July 1969. HMM-774 initially operated UH-34D Sea Horse helicopters. In 1970, the CH-46 replaced the UH-34 and in 1971 the squadron was assigned under the command of the 4th Marine Aircraft Wing. In January 1991, HMM-774 was mobilized as an element of Marine Aircraft Group 26, I Marine Expeditionary Force (I MEF) in support of Operation Desert Shield and Desert Storm. In July 2004, the squadron was mobilized and deployed to Al Asad, Iraq in support of Operation Iraqi Freedom from August 2004 to March 2005 and from September 2005 to March 2006. The squadron was demobilized during July 2006.

As of April 2015, HMM-774 continues to gradually retire aircraft leading to a complete disposition of the CH-46E by December 2015. Retirement of the final aircraft around that time will bring an end to the last dedicated Marine medium helicopter squadron operated by the Marine Corps. HMM-774 became designated as VMM-774 in January 2016 as the squadron received its first V-22 and later took its first test flight in April 2016. VMM-774 declared Final Operating Capability in April 2018.

As of January 2020, VMM-774 no longer maintains any CH-46E aircraft. They have all been retired previously.
