# 85th Test and Evaluation Squadron

The 85th Test and Evaluation Squadron is part of the 53d Wing at Eglin Air Force Base, Florida. It conducts testing and evaluation for the F-15 Eagle, F-15E Strike Eagle, and F-16 Fighting Falcon airframes.

## Mission

The 85th Test and Evaluation Squadron is responsible for conducting operational test and evaluation, tactics development, and programs for F-15C, F-15E, and F-16CM aircraft. It uses specially instrumented aircraft to test and evaluate current and future weapons, the newest air-to ground munitions, air-to-air missiles, electronic warfare systems, and associated components and avionics.
The squadron provides operational fighter expertise to United States Air Force Headquarters, Department of Defense agencies, and the aerospace industry in developing future aircraft and in employment techniques and concepts. The 85th focuses on air-to-air missile employment and tactics, suppression and destruction of enemy air defenses and lethal precision engagement.

## History
### World War II

Activated on 9 February 1942. Moved to Egypt, October–November 1942, and became part of Ninth Air Force.
Trained with Curtiss P-40 Warhawks's while moving westward in the wake of the British drive across Egypt and Libya to Tunisia. Although many of the unit's pilots flew combat missions with other organizations, the 79th group itself did not begin operations until March 1943. By escorting bombers, attacking enemy shipping, and supporting ground forces, took part in the Allied operations that defeated Axis forces in North Africa, captured Pantelleria, and conquered Sicily.
Assigned to Twelfth Air Force in August 1943 and continued to support British Eighth Army by attacking troop concentrations, gun positions, bridges, roads, and rail lines in southern Italy. Operated in the area of the Anzio beachhead, January–March 1944. Participated in the drive on Rome, March–June 1944, and converted to P-47 Thunderbolts during that time. Flew escort and strafing missions in southern France during August and September 1944, and afterward engaged in air interdiction and close air support operations in northern Italy.
Remained overseas as part of United States Air Forces in Europe after the war as part of the occupation force. Transferred, without personnel and equipment, to the US in June 1947. Inactivated on 15 July 1947.

### Air Defense Command

Reactivated in 1952 as part of Air Defense Command as an air defense squadron, initially equipped with F-51D Mustang fighters at Scott Air Force Base, Illinois with a mission for the air defense of St Louis and the western Ohio River Valley. Re-equipped in January 1953 with F-86D Sabre Interceptors. In 1957 began re-equipping with the North American F-86L Sabre, an improved version of the F-86D which incorporated the Semi Automatic Ground Environment, or SAGE computer-controlled direction system for intercepts. The service of the F-86L destined to be quite brief, since by the time the last F-86L conversion was delivered, the type was already being phased out in favor of supersonic interceptors, inactivated on 1 March 1960.
