F-22 Raptor Contractors
The Integrated Product Team (IPT) approach is used to develop the F-22. Under the IPT concept, each of the more than 80 permanent teams is completely responsible for its 'product' (i.e. avionics, cockpit, airframe, utilities and subsystems, etc.)-from engineering a part or system, controlling its cost and schedule, and insuring that it can be manufactured and supported once in use. The Air Force's F-22 System Program Office (SPO) has teams that mirror the organization on the contractor side, improving communications across the team.
The F-22 Team was formed in 1986, when Lockheed, Boeing, and General Dynamics (now Lockheed Martin Aeronautics Company) joined forces for the ATF competition. The teaming arrangement, still in place, has allowed unprecedented industry cost sharing and takes advantage of the companies' strengths in advanced technology application, production capability, and systems integration.
Lockheed Martin Aeronautics Company (LM Aero) serves as the prime contractor on the F-22 program and a majority of work (35 percent) in the EMD and production phases would take place at the company's facility in Marietta, GA (Air Force Plant 6). The remaining two-thirds of the work is being performed at both LM Aero facility in Fort Worth, TX (Air Force Plant 4) and at Boeing's plant in Seattle, WA.
Lockheed Martin Aeronautical Systems (Marietta, GA) is responsible for overseeing overall weapon system integration; developing and constructing the forward fuselage, including the crew station; the vertical fins and stabilators; wing and empennage leading edges, flaps, and flaperons; landing gear; and spearheading avionics architecture development and functional design, as well as displays, controls, the air data system, and apertures. When completed in August 2001, the F-22 final assembly line is housed in Building L-45 adjacent to the programís headquarters Building (L-22) and other key program facilities such as the radar cross section verification facility (L-63); robotic coatings facility (L-64) and its expansion; the preflight work area (L-10); the F-22 avionics development center (L-11); and the AVIF.
Lockheed Martin Tactical Aircraft Systems (Fort Worth, TX) is responsible for developing and constructing the mid-fuselage; armament; providing the tailored INEWS, CNI, stores management systems and inertial navigation systems; and development of the support system.
Boeing is responsible for the wings and aft fuselage; structures for installation of the engines, nozzles, and auxiliary power unit; operation of the Avionics System Integration Laboratory, and the 757 Avionics Flying Laboratory; and development of the training, life support, and fire protection systems.
Pratt & Whitney is under separate contract from the Air Force to provide the F-22's engines. The F119-PW-100 is a new, higher thrust-to-weight engine that is designed for efficient supersonic operation without afterburner (called supercruise), and with increased durability over current engines. Pratt & Whitney would build 26 flightworthy engines for use in the EMD flight test program. Each F-22 is powered by two F119 engines.
