First test cell installed at Aeropropulsion Systems Test Facility 40 years ago this month

The Aeropropulsion Systems Test Facility (ASTF) is pictured here at dusk. The first of two 550,000-pound test cell structures was pushed into the then-under construction ASTF building at Arnold Air Force Base in May 1980. ASTF was dedicated in October 1984. The integration and activation of the facility followed, and ASTF reached initial operational capability in September 1985. (U.S. Air Force photo)
