F-22 Raptor is a stealth fighter made by the United States. It was originally envisioned as air superiority fighter for use against Soviet aircraft, but the aircraft is equipped for ground attack, electronic warfare and signals intelligence. This aircraft through a long development period, prototype version was named YF-22, three years before it was officially adopted was named F/A-22, and eventually was named the F-22A when it officially came into use in December 2005. Lockheed Martin Aeronautics is the prime contractor is responsible for the majority of the airframe, weapons, and assembling the F-22. Then his partner, Boeing Integrated Defense Systems provides the wings, avionics equipment, and pilot and maintenance training.
F-22 also can maneuver very well in supersonic and subsonic speeds. The use of steering thrust makes a sharp turn, and perform extreme maneuvers such as Herbst Maneuver, Cobra Pugachev, and Kulbit. F-22 also can maintain a constant attack angle greater than 60 °. Altitude flying also affect the attack. In a military exercise in Alaska in June 2006, F-22 pilots said that the ability to fly at higher altitudes than other aircraft is one of the determinants of the F-22 victory in the practice.
F-22 does not depend on radar absorbing material such as the F-117 Nighthawk. The use of this material could not bear to bring up the problem because of bad weather. And unlike airplane bomber B-2 Spirit stealth that require special hangars, the F-22 can be given usual care in the hangar. [16] In addition, the F-22 also has a system called "Signature Assessment System", which will indicate when traces radar plane was already high, until eventually require repairs and maintenance.
Use of afterburner also make aircraft emissions more easily captured by the radar, it is estimated is the reason why the F-22 is focused to be able to have the ability supercruise.
