Records indicate that the contingency deception plan had been in place for the first two tests but did not affect their outcomes.Records of the deception program for HOE show that it was superimposed on the ongoing technical program after the demonstration hardware had been designed and fabricated and that it was discontinued before the third flight. No deceptive explosion occurred on flights 1 and 2 because the interceptor missed the target by too great a distance. The plan was dropped prior to HOE 3. Analyses of HOE 4 test data are consistent with the Army's conclusion that the interceptor and target collided. Records also support the conclusion that the interceptor was guided during its final maneuvers by its onboard infrared sensor. While some hardware related to the deception remained onboard the target, it did not affect the outcome of HOE 4. The hardware to implement a deceptive explosion did not interfere with a normal test intercept.
