EXAMPLES OF RELIABILITY DEGRADATION

Precedents for discounting the effectiveness of aging weapons when compared to “as-built” performance:

Soviet-made SA-2 surface-to-air missiles achieved a single-shot kill probability of about 1% during the Viet Nam war

AIM-9E Sidewinder air-to-air missile achieved a 8% to 10% kill probability in Viet Nam

AIM-7E Sparrow achieved a better but still disappointing 12% to 15% kill probability, versus the 70% demonstrated in initial or OT&E type tests

During the Falklands the aging British Seacat surface-to-air missile achieved only a 10% kill probability while performance characteristics based on design and as-built reliability were significantly higher
