Fighters For The Missile Era

Armament of the F-15A was essentially that of the F-4E Phantom: four Sparrow and four Sidewinder missiles and a 20-mm M61 gun. An APQ-63 radar provided long-range search up to 115 miles and semi-active homing for the 510-pound AIM-7F Sparrows carried below the engine nacelles. The 199-pound AIM-9L heat-seeking Sidewinders were below the wings and the gun with 940 rounds was in the starboard wing root, opposite the inflight refueling receptacle on the port side. Pylons provided for three 600-gallon drop tanks could also accommodate a variety of bombs and stores, although ground attack was not then part of the required mission.
Powered by two Pratt & Whitney F100-PW-100 turbofans, the F-15A’s structure included 37.3 percent aluminum, 25.8 percent titanium, and 5.5 percent steel. Twin vertical fins were tipped with ECM antenna, and an air refueling receptacle was in the left wing.
Production go-ahead on a fly-before-buy basis was approved in February 1973 for the first 18 F-15A fighters and two TF-15A trainer development aircraft, and 23 F-15A and seven TF-15B production aircraft. The first two-seater flew July 7, 1973, and all the dual-control trainers were redesignated F-15B. They retained all the combat gear, excepting ECM. Deliveries to TAC’s training wing at Luke AFB began in November 1974.
In January 1975, the stripped-down 19th aircraft set world climb records. That F-15A climbed to 12,000 meters (39,372 feet) in 59 seconds; the previous record by an F-4 was 77 seconds. A MiG-25 had set a 30,000 meter (98,430 feet) record in 243.5 seconds; the F-15A did it in 207 seconds, although the Soviet aircraft recaptured the latter record soon after.
The first operational unit delivery was made in January 1976 to the 1st Tactical Fighter Wing at Langley AFB, which formed three 24-plane squadrons during the year. Next came the 36th TFW, which deployed to Germany in April 1977, and the 49th TFW at Holloman, New Mexico. Annual increments to the production program followed regularly until 384 F-15A and 61 F-15B Eagles were built. The safety record was the best of any American fighter.
Israel was the F-15’s first foreign customer, buying 23 F-15As and two F-15Bs for $30 million each; the first four being refurbished pre-production F-15As aircraft delivered on December 10, 1976. The F-15’s first combat came on June 27, 1979, when Israeli F-15A AIM-9 missiles downed four Syrian MiG-21s. Continued conflicts cost 16 more Syrian aircraft and led to a great air battle over the Bekaa valley in Lebanon in June 1982, when Israeli F-15As were credited with 40 Syrian fighters without loss. Eight F-15As flew 1,280 miles, with air refueling, to bomb a PLO base in Tunis on October 1, 1985.
