Abstract:
Defensive infrared countermeasures systems are integral to the survival of combat and combat support aircraft in the modern battlefield environment. DOD studies have concluded that 90 percent of the aircraft losses resulting from hostile fire from 1975 through 1985 were attributable to infrared seeking missiles. A number of countermeasures systems exist that combine to reduce the vulnerability of aircraft to threats stemming from weapon systems that use infrared guidance technology. Suppression systems, jammers, and missile detection systems are complementary countermeasures systems and are important to ensure optimal protection of aircraft from the infrared seeking threat. The overall audit objective was to evaluate the design adequacy of the Hot Metal Plus Plume Suppression system for the AH-1 Cobra helicopter, the Louvered Scarfed Shroud Suppression system for the OV-1 Mohawk aircraft, and the ANALQ-144 Infrared Jammer for a variety of lift helicopters. Also, we evaluated the adequacy and sufficiency of internal controls related to the three systems.
