The USAF F-15A/B air superiority fighter, built by the McDonnell Aircraft Company and introduced into active service in 1974, has demonstrated exceptional performance and combat readiness. Recent introduction of the F-15C/D with increased internal fuel, provisions for conformal fuel tanks, increased takeoff gross weight plus incorporation of a Radar Programmable Signal Processor provides improvement in range and mission flexibility. These improvements will enhance already demonstrated capabilities for performing other roles, i.e., in-weather strike, defense suppression and real-time reconnaissance in the post 1983 time period at a fraction of the cost to develop a new aircraft.
