The Lockheed Martin/Boeing F-22 Raptor is an air dominance fighter due to replace the F-15C Eagle’s of the United States Air Force.

In October 1986 the USAF launched the Advanced Tactical Fighter program and invited Lockheed and Northrop to build two prototypes each, by specification of the USAF, to be evaluated and tested.

For the engines General Electric (YF120) and Pratt & Whitney (YF119) were the choice of the USAF to build test models for the new ATF.

Lockheed got together with General Dynamics and Boeing and their YF-22 flew for the first time on September 29th 1990. Northrop/McDonnell Douglas’s YF-23 made it’s first flight on August 27th that same year.?

The USAF selected Pratt &Whitney to develop their YF119 in April 1991.

The first F-22A (first of eleven) development aircraft took off on September 7th 1997, and the second on June 28th 1998. The first production Raptor will be delivered to the USAF around early 2003, after that the first operational unit will be active in 2005. A production of 295 Raptors has been authorized so far.
