A fifth-generation Fighter Jets is a jet fighter aircraft classification which includes major technologies developed during the first part of the 21st century.
F-22 Raptor (USA).
The F-22 Raptor is considered the first 5th-generation fighter in the U.S. Air Force inventory, using low observable technologies, modern avionics and efficient engines to offer an air superiority fighter unmatched by any other modern military. The F-22 Raptor, a critical component of the Global Strike Task Force, is designed to project air dominance, rapidly and at great distances and defeat threats attempting to deny access to our nation’s Air Force, Army, Navy and Marine Corps. The F-22 cannot be matched by any known or projected fighter aircraft.
Lockheed Martin F-35 (USA).
The F-35, also known as the Lightning II, is a new multi-role fighter. One of its variants, the F-35B achieved initial operational capability with the US Marine Corps in 2015. The F-35 was developed under a Joint Strike Fighter program, which was intended to replace existing aircraft types with a common fighter. In the near future the F-35 will replace the AV-8B, A-10, F-16 and F/A-18 warplanes in service with the US military. Also it is being exported to a number of countries.
Sukhoi Su-57 (Russia).
The Su-57 is a new Russian fighter aircraft. It started life of the PAK FA (or Future Frontline Aircraft System). In 2017 this aircraft received a regular Su- designation. This new stealthy aircraft was designed intended to replace ageing MiG-29 and Su-27 fighters. It can be seen as a Russian answer to the US F-22 Raptor. Development of this aircraft commenced in 2001. A prototype was revealed and made its first flight in 2010. It was planned that in 2018 a first batch of 12 pre-production fighters will be delivered to the Russian Air Force. In fact in 2018 a couple of pre-production Su-57 fighters were deployed in Syria.
Chengdu J-20 (China).
The Chengdu J-20 is the new China’s stealth fighter. It was designed to compete against fifth-generation fighters, such as the US F-22 Raptor and advanced fourth-generation fighters, such as the Russian Su-57 (previously known as PAK-FA). It is speculated, that development of the J-20 was assisted by the Russian MiG aviation company. Low-rate initial production of this stealthy aircraft commenced in 2015. First operational J-20 stealthy fighters were delivered to Chinese air force in 2016. This stealthy fighter was officially adopted by China’s air force in 2017.
