History
Marine Heavy Helicopter Squadron-366 (HMH-366) was originally activated on September 30, 1994 at MCAS Kaneohe Bay, Hawaii as part of Marine Aircraft Group 16 (MAG-16). As the fourth active CH-53D Sea Stallion squadron, it was the only Hawaiian home-grown helicopter squadron in active service in the Marine Corps. The squadron's callsign, "Hammerhead," was inspired by the fact that Kaneohe Bay is home to the world's largest hammerhead shark population, and the original unit patch featured a hammerhead shark leaping over an airborne CH-53D.

While active in Hawaii, the squadron deployed to the Pacific Missile Range Facility (PMRF), Barking Sands on Kauai, the Pohakuloa Training Area on the Big Island, and completed a successful mainland deployment in support of Combined Arms Exercises (CAX) 9-98 and 10-98, and Weapons and Tactics Instructors Course (WTI) 2-00. The squadron also supported a four aircraft deployment to Dhaka, Bangladesh for presidential support of President Clinton’s visit to the country. On 1 October 2000, with a limited number of available CH-53Ds in the Marine Corps, and no addition CH-53Ds being produced, the squadron was de-activated as part of a realignment plan to redistribute the units’ personnel and aircraft to the remaining three CH-53D squadrons in Hawaii (HMH-362, HMH-363, HMH-463), thereby increasing the Primary Authorized Aircraft (PAA) of those squadrons from eight to ten aircraft.

The squadron was reactivated on 30 September 2008 as part of the Marine Corp's expansion.
