The squadron provided essential aviation logistical, maintenance, and administrative support to Marine aviation units, particularly those assigned to Marine Aircraft Group 11 (MAG-11). Throughout its history, including significant service during the Vietnam War, H&MS-11 played a vital role in ensuring the operational readiness of aircraft and equipment. The squadron was later redesignated as Marine Aviation Logistics Squadron 11 (MALS-11), continuing its legacy of aviation support within the Marine Corps.
