The F-22 also has an inherent air-to-surface capability. A combination of
improved sensor capability , improved situational awareness, and improved
weapons provides first-kill opportunity against the threat. The F-22 possesses a
sophisticated sensor suite that allow the pilot to track, identify, and shoot
the threat before it detects the F-22. Significant effort is being placed on
cockpit design and avionics fusion to improve the pilot's situational awareness.
Advanced avionic technologies allow the F-22 sensors to gather, integrate, and
display essential information in the most useful format to the pilot.
Raptor History
Prior to its selection as winner of what was then known as the
Advanced Tactical Fighter (ATF) competition, the F-22 team conducted a 54-month
demonstration/ validation (dem/val) program. The effort involved the design,
construction and flight testing of two YF-22 prototype aircraft. Two prototype
engines, the Pratt & Whitney YF119 and General Electric YF120, also were
developed and tested during the program. The dem/val program was completed in
December 1990.
Much of that work was performed at Boeing in Seattle, Lockheed
(now known as Lockheed Martin) facilities in Burbank, Calif., and at General
Dynamics' Fort Worth, Texas, facilities (now known as Lockheed Martin Tactical
Aircraft Systems). The prototypes were assembled in Lockheed's Palmdale, Calif.,
facility and made their maiden flight from there. Since that time Lockheed's
program management and aircraft assembly operations have moved to Marietta, Ga.,
for the EMD and production phases.
A $9.55 billion contract for Engineering and Manufacturing
Development (EMD) of the F-22 was awarded to the industry team of Boeing and
Lockheed Martin in August 1991. Contract changes since then have elevated the
contract value to approximately $11 billion. Under terms of the contract, the
F-22 team will complete the design of the aircraft, produce production tooling
for the program, and build and test nine flightworthy and two ground-test
aircraft. In February 1995, the Air Force
customer approved the final design of the F-22 air vehicle and confirmed that
the program was ready to proceed to fabrication and assembly. The Air Force
plans to procure 339 F-22s, and production is scheduled to run through 2013.
