LOCKHEED-BOEING-GENERAL DYNAMICS YF-22 RAPTOR

n 1981 the Air Force developed a requirement for an Advanced Tactical Fighter as a new air superiority fighter. It would take advantage of the new technologies in fighter design on the horizon, including composite materials, lightweight alloys, advanced flight control systems, higher power propulsion systems and stealth technology. Air Force leaders believed that these technologies would make aircraft like the F-15 and F-16 obsolete early in the 21st century.

In 1985 the Air Force sent out formal requests for proposals to a number of aircraft manufacturers and selected two industry teams, one led by Lockheed and the other by Northrop, to build the prototypes. The Lockheed and Northrop teams each built two prototypes, one with General Electric YF120 engines and one with Pratt & Whitney YF119 engines. The Lockheed aircraft was designated YF-22 and the Northrop aircraft was YF-23.

After extensive flight tests the Lockheed-Boeing-General Dynamics team won the airframe competition and Pratt & Whitney the engine contract. In 1997 the Air Force sent the YF-22 prototype that had been equipped with GE engines to the museum. After it was refurbished and equipped with two Pratt & Whitney YF-119-PW-100 engines, the YF-22 was placed on display in 1998.

TECHNICAL NOTES:
Armament: One M61A1 20mm multi-barrel cannon; internal stations can carry AIM-9 infrared (heat seeking) air-to-air missiles and AIM-120 radar-guided air-to-air missiles or 1,000-lb. Joint Direct Attack Munitions (this prototype does not have a gun bay)
Engines: Two Pratt & Whitney YF119-PW-100s (this aircraft originally flew with General Electric YF120-GE-100 engines)
Maximum speed: Mach 2+
Service ceiling: Above 50,000 ft.
Span: 43 ft.
Length: 64 ft. 2 in.
Height: 17 ft. 9 in.
