Modern - T-50

The PAK FA (literally Prospective Airborne Complex of Frontline Aviation) is a fifth generation fighter programme of the Russian Air Force. The T-50 is the aircraft designed by Sukhoi for the PAK FA programme. The aircraft is a a stealthy, single-seat, twin engine jet fighter, and will be the first operational aircraft in Russian service to use stealth technology. It is a multirole combat aircraft designed for the air superiority and ground attack functions. It combines supercruise, stealth, manoeuvrability, and advanced avionics to overcome previous generation fighter aircraft along with many ground and maritime defences.

The PAK FA is intended to be the successor to the Mig 29 and SU-27 in the Russian Air Force and serve as the basis for the Fifth Generation Fighter Aircraft (FGFA) being co-developed by Sukhoi and Hindustan Aeronautics Limited (HAL) for the Indian Air Force. The T-50 prototype first flew on 29 January 2010 and production aircraft is slated for delivery to the Russian Air Force starting in 2016. The prototypes and initial production batch will be delivered with a highly upgraded variant of the AL-31F used by the Su-27 family as interim engines while a new clean-sheet design power plant is currently under development. The aircraft is expected to have a service life of up to 35 years.
