The Lockheed Martin F-22 "Raptor" is powered by dual Pratt & Whitney F-119-PW-100 turbofan engines incorporating both afterburning and thrust vectoring capability. Although the exact amount of maximum thrust is classified information, many sources place it at approximately 35.000 lbf per engine. The aircraft is able to achieve a maximum speed of Mach 2 (2.120 km/h) with afterburners while supercruising allows the aircraft to fly at speeds exceeding Mach 1.7. All these speeds have not been confirmed as the aircrafts true top-speed is largely unknown and depends on more factors than engine power alone. It is however given that the aircraft is able to reach supersonic speeds without the use of afterburners, called supercruise, and is a great advantage to fuel-efficiency as afterburner usage greatly reduces flight time.
The F-22 is designed to be highly maneuveralbe, at both subsonic and supersonic speeds and is achieved by making use of thrust vectoring capability. Thrust vectoring allows the aircraft to turn tightly and perform extremely high alpha maneuvers. Anothter advantage is that the aircraft is capable of performing such maneuvers at high altitude as F-22 pilots showed during exercises in Alaska in June 2006. |

In order to carry out its primary role, that of air-to-air combat, the F-22 will carry six AIM-120C and two AIM-9 missiles. For its air-to-ground role, the Raptor is able to carry two 1,000 pound-class JDAM, two AIM-9, and two AIM-120C missiles internally. In adverse weather conditions the F-22 has the ability to supplement the F-117 Nighthawk for air-to-ground missions after achieving air dominance due to the carriage of the GPS-guided JDAM. Furthermore, the F-22's combat configuration is "clean", meaning that all armament is carried internally with no external stores. This is definately an important factor in the stealth characteristics of the F-22 as it dramatically reduces drag, which improves its range significantly. In addition, the F-22 has four under wing hardpoints, each of them capable of carrying 5,000 pounds. Depending on the mission, the under wing hardpoints can facilitate either a 600-gallon fuel tank or two LAU-128/A missile launchers.

Overall, there are two basic external configurations for the F-22, namely;
- Four 600 gallon fuel tanks, carrying no external weapons. This configuration is used whenever the aircraft is being ferried and extra range is needed. Furthermore, a BRU-47/A rack is used on each pylon to hold the external fuel tanks.
- Two 600 gallon fuel tanks together with four missiles. In this configuration the aircraft can be utilized after air dominance in a battle area has been secured, and extra loiter time and firepower is required for combat Air Patrol (CAP).
