F-22 Raptor
I. Introduction:
Modern weapon systems have traditionally contained many more specifications and greater detailed Statements of Work [SOW] than those of the past. Contrast the Army Signal Corps SOW for the Wright Brothers' heavier-than-air flying machine in 1908 to the Air Force SOW for the Advanced Tactical Fighter in 1986. Requirements in the 1908 SOW (e.g., be easily taken apart for transport in Army wagons and be capable of being reassembled for operation in an hour, carry 350 pounds for 125 miles, and maintain 40 miles per hours in still air) and other contract conditions were specified on one page. The requirements section in the 1986 SOW for the Air Force Advanced Tactical Fighter was 85 pages long with 300 paragraphs of requirements.
Subsequent to studies, an RFP was issued in July 1986. In October 1986, the Phase I Demonstration/Validation (Dem/Val) program was initiated, and the F-22's operational requirements, or Key Performance Parameters, were established. These parameters were documented in the System Operational Requirements document in 1987 and supported a Milestone I decision. Two contractor teams, Northrop/McDonnell-Douglas and Lockheed/Boeing/General Dynamics were selected in October 1986 for the initial 50 month demonstration/validation phase flyoff between the YF-22 and YF-23, the original designations of the F/A-22. The rollout of the prototypes was initially scheduled for mid 1989, but ongoing slippages delayed this. Both ATF prototypes were approximately 10% larger than the F-15 and both carry approximately twice the internal fuel of an F-15C, while both have about 50% more wing area at about 30% greater combat weight. As such both aircraft clearly illustrate the long range air superiority mission which was originally envisaged for the aircraft, penetrating deep into Soviet airspace to destroy air defence aircraft and to disrupt Soviet offensive air operations.
