The 77th Aeronautical Systems Wing (77 ASW) is an inactive United States Air Force unit, last assigned to the Aeronautical Systems Center at Wright-Patterson Air Force Base, Ohio.


Its World War II predecessor unit, the 77th Reconnaissance Group supported ground units in training by flying reconnaissance, artillery adjustment, fighter, and bomber missions, and in the process trained reconnaissance personnel who later served overseas.


During World War II the 77th supported ground units in training by flying reconnaissance, artillery adjustment, fighter, and bomber missions, and in the process trained reconnaissance personnel who later served overseas. The 113th Observation Squadron flew antisubmarine patrols over the Gulf of Mexico from March until June 1942 when it was relieved by another squadron (128th). Still another squadron (120th) patrolled the Mexican border from March–July 1942. A detachment of the 77th served in India from February until July 1943. The 77th was inactivated in 1943.

The 77th was redesignated in 1985, though this was a 'paper' change that effectively went no further than an Air Staff filing cabinet. It was then consolidated with the 2852nd Air Base Wing in 1994 to provide services and support for McClellan AFB with its satellite installations and the Sacramento Air Logistics Center with its tenant organizations (the 2852nd had been performing this duty since 1 August 1953) until the base was officially closed in 2001.

The 77th Aeronautical Systems Group moved from Brooks City-Base, San Antonio to Wright-Patterson AFB in mid-2009.


The 77 ASW supported the Aeronautical Systems Center. Its units perform a variety of missions

  • Human Systems Group
  • Provided advanced performance, survival, and force protection capabilities to U.S. and allied air, ground, and naval forces through development, production, and sustainment of human-centered systems including aircrew life support, egress, survival, aeromedical equipment, medical information, aerovac equipment testing/certification, AF uniforms, and aircraft mishap analysis.
  • Simulator Systems Group
  • Responsible for the development, production, test, integration, deployment, modification, and sustainment of common training solutions for joint ground-based training and mission rehearsal systems.
  • Aging Aircraft Systems Squadron
  • Developed and fielded products that enhance the Air Force's aircraft fleet availability and mission capability while reducing total ownership cost. The squadron is responsible for the development, acquisition, and fielding of cross-enterprise materiel solutions that enhance fleet availability and mission capability.
  • Propulsion Systems Squadron
  • Responsible for the development, production, test, and fielding of propulsion systems for the Joint Strike Fighter, F/A-22, and C-17. It also manages the Component Improvement Program, critical sustaining engineering for Air Force propulsion, and modernization of all Air Force propulsion systems, future propulsion capabilities, and allied F-15/F-16 engines.
  • Combat Electronics Systems Squadron
  • Responsible for the development, testing, acquiring, fielding and sustainment of materiel capabilities for multiple Department of Defense and allied aircraft weapon systems.
