Ballistic Missile Defense: Records Indicate Deception Program Did Not Affect 1984 Test Results

Pursuant to a congressional request, GAO investigated allegations concerning deception in the Army's Homing Overlay Experiment (HOE), focusing on: (1) the nature of any deception plan for HOE; (2) whether the interceptor and target collided as claimed; (3) whether the interceptor had an undisclosed guidance subsystem; (4) whether the target and its infrared emissions were appropriate for the demonstration; and (5) whether the Army and the Department of Defense (DOD) accurately represented the performance of HOE 4.
