Sukhoi PAK FA T50

The PAK FA (Russian: ПАК ФА, "Prospective Airborne Complex of Frontline Aviation") is a fifth-generation fighter programme of the Russian Air Force. The T-50 is the name of the prototype aircraft designed by Sukhoi for the PAK FA programme. It was designed with cooperation between Russia and India. The aircraft is a stealthy, single-seat, twin-engine jet fighter, and will be the first operational aircraft in Russian service to use stealth technology. It is direct evolution of the experimental Sukhoi 35/45 Berkut (Russian: [..], Golden Eagle), which in turn was a testbed of new aviation technologies and composite materials, and the main fuselage was from Su27. It is a multirole fighter designed for air superiority and attack roles. The fighter is planned to have super cruise, stealth, super maneuverability, and advanced avionics to overcome the prior generation of fighter aircraft as well as ground and maritime defenses. The service time is estimated to 35 years.
The PAK FA is intended to be the successor to the MiG-29 and Su-27 in the Russian Air Force and the design team sacrificed a part of the stealth capabilities of the aircraft by having the jet exhausts with vector thrust technology, whereas in the US stealth aircrafts they are covered and using vectoring nozzles. This gives the T50 more maneuverability over the F22.

In the latest Singapore Airshow, Lokheed analysts have described the T50 as "A conventional fourth generation jet with a stealthy look" noting significant lack of technologies to be stated as a 5th generation jet. The Russians are more considered by the lack of orders in the Asia region, as its higher price makes it less lucrative than the current Su35s. Both countries, USA and Russia, contest for the 5th generation aircrafts in the Asian market. SOURCE
