Sukhoi/HAL FGFA

The Sukhoi/HAL Fifth Generation Fighter Aircraft, or FGFA, was a fifth-generation fighter concept based on the Russian Su-57 that Sukhoi and Hindustan Aeronautics were developing for the Indian Air Force; the programme was later referred to as the Prospective Multi-Role Fighter. The completed aircraft was to include 43 improvements over the Su-57, including advanced sensors, networking and combat avionics, and the Indian version would have been a two-seater with a pilot and a co-pilot or weapon systems operator. Russia and India agreed in early 2007 to study the programme, and a preliminary design contract was reported in 2010 with HAL taking a 25 percent share of the design work. About 500 aircraft were planned, 250 for Russia and 214 for India. India was reported to have withdrawn in 2018, and in 2019 the Indian Air Force chief said the country would not import stealth fighters like the Su-57.
