The F-22A Raptor is an advanced single-seat twin-engine stealth fighter aircraft developed for the US Air Force. Lockheed Martin is the prime contractor responsible for the majority of the airframe and weapon systems. The Raptor has unprecedented air combat capabilities due to its stealth, aerodynamic performance, and situational awareness. It is powered by two Pratt & Whitney afterburning turbofan engines and has an internal cannon and capacity for six AIM-120 AMRAAMs or other weapons internally and on external hardpoints.

Advanced Tactical Fighter Aircraft

3. Introduction
• The Lockheed Martin F-22 Raptor is a single-seat, twin-engine, all
weather stealth tactical fighter aircraft developed for the United States Air Force (USAF).
• Lockheed Martin is the prime contractor and is responsible for the majority of the airframe,
weapon systems, and final assembly of the F-22, while program partner Boeing provides the
wings, aft fuselage, avionics integration, and training systems.
• The aircraft was variously designated F-22 and F/A-22 prior to formally entering service in
December 2005 as the F-22A.
• The Raptor's combination of stealth, aerodynamic performance, and situational awareness gives
the aircraft unprecedented air combat capabilities.

5. Design
• The F-22 is powered by two Pratt and Whitney F119-100 engines.
• The F119-100 is a low bypass after-burning turbofan engine providing 156kN thrust.
• The TRW CNI communications, navigation and identification system includes an intra-flight data
link, joint tactical information distribution system (JTIDS) link and an identification friend or foe
(IFF) system.
• The aircraft has a Northrop Grumman (formerly Litton) LTN-100G laser gyroscope inertial
reference, a global positioning system and a microwave landing system.

7. Features
• The F-22 construction use titanium for its high strength-to-weight ratio in critical stress areas, including
some of the bulkheads, and also for its heat-resistant qualities in the hot sections of the aircraft.
• The cockpit has six color liquid crystal displays. The Kaiser Electronics projection primary multifunction
display provides a plan view of the air and ground tactical situation including threat identity, threat
priority and tracking information.
• A BAE Systems head-up display (HUD) shows target status, weapon status, weapon envelopes and shoot
cues. A video camera records data on the HUD for post-mission analysis.
• The AN/APG-77 radar uses an active electronically scanned antenna array of 2,000 transmitter / receive
modules, which provides agility, low radar cross-section and wide bandwidth.

9. Weapons
• A variant of the M61A2 Vulcan cannon is installed internally above the right air intake. The
General Dynamics link less ammunition handling system holds 480 rounds of 20mm ammunition
and feeds the gun at a rate of 100 rounds a second.
• The F-22 has four hard points on the wings, each rated to carry 2,270kg, which can carry AIM-
120AAMRAAM or external fuel tanks.
• The Raptor has three internal weapon bays. The main weapons bay can carry six AMRAAM AIM-
120C missiles or two AMRAAM and two 1,000lb GBU-32 joint direct attack munition (JDAM).
• The side bays can each be loaded with one Lockheed Martin / Raytheon AIM-9M or AIM-9X
Sidewinder all-aspect short-range air-to-air missile.
