Electronic Warfare : Comprehensive Strategy Needed for Suppressing Enemy Air Defenses: Gao-01-28

To suppress enemy air defenses, U.S. armed forces use specialized aircraft designed to neutralize, destroy, or temporarily degrade enemy air defense systems through either physical attack or electronic warfare. Concerns have been raised that the Air Force's decision to retire EF-111 and F-4G suppression aircraft, combined with a growing threat from increasingly sophisticated enemy air defenses, has created a gap between the services' suppression capabilities and their needs. GAO (1) examined the steps that the military has taken since 1996 to improve its ability to suppress enemy air defenses and (2) evaluated the services' plans to eliminate any gap between their suppression capabilities and needs. GAO found that the services have improved their suppression capabilities, such as increasing the size of their fleets of F-16CJ and EA-6B suppression aircraft, improving the electronic warfare and missile systems on these aircraft, studying cost-effective alternatives for suppression in the future, and reviewing electronic warfare programs to determine if these programs are adequately managed, prioritized, and funded. However, GAO also found that current suppression capabilities are not adequate and that no comprehensive, cross-service strategy exists for achieving the suppression mission.
