F-15 Eagle McDonnell Douglas
(now Boeing)
F-15 Eagle
Air Superiority Fighter

DESCRIPTION:
Forseeing the need to replace its fleet of F-4 Phantoms, the US Air Force issued the FX requirement for a long-range air superiority fighter in 1965. Performance requirements called for beyond visual range air-to-air capability, close-in dogfighting capability, twin engines, an internal gun, sufficient ferry range to deploy to Europe without refueling, and a maximum speed of Mach 2.5. McDonnell Douglas was selected over rivals North American and Fairchild Republic to build what would become the F-15 Eagle.

The McDonnell Douglas approach incorporated advanced aerodynamics into a large wing that gives the F-15 a low wing loading and good agility for such a large aircraft. However, transonic buffet and flutter problems were encountered in early flight tests requiring an enlarged airbrake, cropping of the trailing edges of the wingtips, and adding notched dogtooths to the tailplanes. The addition of external compression adjustable inlets and the extensive use of titanium allowed the F-15 to meet its Mach 2.5 speed requirement at high altitude, though the speed is limited to Mach 1.78 when armed. The F-15 revolutionized cockpit design by seating the pliot high under a large canopy to provide excellent visibility, and the use of a Hands On Throttle and Stick (HOTAS) arrangement places all vital controls near the pilots hands.

Although the Air Force had originally intended to order some 730 F-15A single-seat fighters and F-15B two-seat combat-capable trainers, only about 410 were built before production switched to the more capable F-15C/D models. These newer aircraft feature a new radar warning receiver, software updates, and conformal fuel tanks along the sides of the engine inlets that provide increased fuel capacity while not interfering with weapons carriage. Later F-15C/D models also received more powerful F100-220 engines plus the faster APG-70 radar with better resolution and greater memory when compared to the earlier APG-63.

Older F-15A/B and F-15C/D models have also been progressively upgraded through an ambitious Mid-Service Improvement Program (MSIP). Among the updates include upgrading to newer variants of the APG-63 radar, intoducing new avionics, and replacing outdated analog computers with digital central processors. Other advances include adding a new weapons display screen, improving internal countermeasures, and adding compatibility with the AIM-120 AMRAAM. The potential of the basic F-15 airframe has been further exploited through the development of the two-seat F-15E strike model that adds a potent surface attack capability.

Older F-15A/C vehicles will begin to be replaced by the F-22 by about 2010, and some of the displaced fighters will likely be converted for use as air defense suppression aircraft.
