H&MS-13

Headquarters and Maintenance Squadron 13 (H&MS-13) was a United States Marine Corps aviation support unit established to provide logistical and maintenance support to Marine aircraft squadrons. Originally activated during the Vietnam War era, H&MS-13 was based at Marine Corps Air Station El Toro in California. The squadron played a critical role in ensuring the operational readiness of Marine aircraft by managing supply, avionics, and intermediate-level aircraft maintenance. In 1988, as part of a Corps-wide reorganization, H&MS-13 was redesignated as Marine Aviation Logistics Squadron 13 (MALS-13), continuing its mission of aviation logistics support for Marine Aircraft Group 13.
