Headquarters & Maintenance Squadron 26 (H&MS-26) was a United States Marine Corps aviation support unit assigned to Marine Aircraft Group 26, 2nd Marine Aircraft Wing. Activated in the 1950s, H&MS-26 provided critical logistical, administrative, and intermediate maintenance support to the helicopter squadrons of MAG-26, especially during deployments and operations. The squadron played a vital role during the Vietnam War era and in subsequent Cold War military exercises and contingencies. In 1988, H&MS-26 was redesignated as Marine Aviation Logistics Squadron 26 (MALS-26), reflecting its evolving role in support of Marine aviation operations.
