第54期 F-22 07/07/2019

Hello everyone, today I would like to introduce you guys a type of plane- the F-22.

Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The prime contractor, Lockheed Martin, built most of the F-22's air-frame and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.

The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. Despite its protracted development and various operational issues, USAF officials consider the F-22 a critical component of the service's tactical air power. Its combination of stealth, aerodynamic performance, and situational awareness enable unbelievably strong air combat capabilities.

The engine of the F-22 is called PW-F119
