Airman Second Class Erv Smalley in Feb 1962 at the Weapons Calibration Hanger with an ARMAMENT TEST SET (ATS), Kincheloe AFB, Michigan. ATS tested the missile armament on the ground in a high altitude, high speed simulated environment known as Short System Ground Check (SSGC) #5. The armament could also be manually tested from the 596 Unit in the right main wheel well as well as the automatic SSGC #5 test. Results were displayed on the ATS via lights and tripped circuit breakers. When necessary, successful ATS ground tests could be substituted for airborne verifications when determining qualifications for standing Alert. [Erv Smalley collection]
