McDONNELL DOUGLAS F-15 EAGLE
Primary Mission: Air Superiority*
The USAF requested development funding for a new air superiority fighter in
1965. On 23 December 1969 it was announced that McDonnell Douglas has been
selected as prime airframe* contractor. First flight of F-15A was made on 27 July
1972. A production go-ahead* for the first 30 operational aircraft was announced on
1 March 1973. By 1 February 1981 a total of 597 Eagles had been delivered.
Designed specifically as an air superiority fighter, The F-15 Eagle has proved equally
suitable for air-to-ground missions without degradation of its primary role. Internal
changes include installation of a modified central computer, a modified signal data
processor for a pilot’s heads-up display* , and new or modified flight/fire control
software. Under a program dubbed “Streak Eagle”, the F-15 demonstrated its climb
capability by capturing eight time-to-height records between 16 January and 1
February 1975.
