F-22 fighter is a kind of fifth generation fighter with single seat, double engine and high stealth. It is the first fifth generation fighter in the world to enter into service.

The combination of stealth performance, sensitivity, accuracy and situational awareness makes F-22 the best fighter in the world in terms of its air-to-air and air-to-ground combat capabilities.

The F-22 fighter is jointly developed by Lockheed Martin company and Boeing company. It has been put into service in the U.S. Air Force in the early 21st century to replace the F-15 fighter. Lockheed Martin is the main contractor responsible for the design of most of the fuselage, weapon systems and final assembly of the F-22. Boeing, the program's partner, provides wings, aft fuselage, avionics integrated systems and training systems. However, due to the high manufacturing cost of the F-22, the lack of clear air-to-air combat tasks caused by the delay of the fifth generation fighter planes of Russia and China, the export ban of raptors and other use plans (including the F-35 and UAVs), all of which led to the early termination of the F-22 production plan. In April 2009, the U.S. Department of defense proposed to stop new orders and finally purchase 187 fighter planes with the approval of Congress. The FY2010 defense authorization act resulted in a lack of funds to produce more F-22. The launch ceremony of the last F-22 was held at Dobbins Air Force Reserve Base on December 13, 2011.
