The Sukhoi PAK FA ( Future Frontline Aircraft System), is a fifth generation fighter aircraft being developed by Sukhoi OKB for the Russian Air Force.

 

The current prototype is Sukhoi’s T-50. The PAK FA when fully developed is intended to replace the MiG-29 Fulcrum and Su-27 Flanker in the Russian inventory and serve as the basis of the Sukhoi/HAL FGFA project being developed with India. A fifth generation jet fighter, it is designed to directly compete with Lockheed Martin’s F-22 Raptor and F-35 Lightning II. The T-50 performed its first flight January 29, 2010. Sukhoi director Mikhail Pogosyan has projected a market for 1000 aircraft over the next four decades, which will be produced in a joint venture with India, two hundred each for Russia and India and six hundred for other countries.
