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. History. During World War II the 77th Observation 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. The group's 5th Observation Squadron moved to Desert Center Army Air Field in March 1943, where it supported units training at the Desert Training Center, later relocating to Thermal Army Air Field in September. It converted entirely to "Grasshopper" aircraft in April 1943, becoming the 5th Liaison Squadron. 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. It was inactivated on 30 June 2010 along with all aeronautical systems wings when the Aeronautical Systems Center was reorganized. Units. The 77 ASW supported the Aeronautical Systems Center.
