Because of the large number of Army personnel enrolled in the air defense school, Fort Bliss saw two large rounds of construction in 1954 and 1958. The former was aimed at creating more barracks facilities, while the latter was aimed at building new classrooms, materials labs, a radar park, and a missile laboratory. Between 1953 and 1957 the Army also expanded McGregor Range in an effort to accommodate live fire exercises of the new missile systems. Throughout the Cold War Fort Bliss remained a premier site for testing anti-aircraft equipment.
