Sukhoi Su-57 Sukhoi/HAL FGFA

On 18 October 2007 Russia and India signed a contract for Sukhoi and Hindustan Aeronautics Limited to jointly develop a derivative of the PAK FA called the Fifth Generation Fighter Aircraft (FGFA). In September 2010 the two countries agreed a preliminary design contract in which each was to invest 6 billion dollars, and a memorandum of understanding for the preliminary design was signed in December 2010; development was expected to take eight to ten years.

The FGFA was intended to be the primary export version of the PAK FA and was to differ from it in 43 ways, with improvements to stealth, supercruise, sensors, networking and combat avionics. Reports on its actual scope conflicted: while India detailed numerous improvements over the baseline PAK FA, Mikhail Pogosyan, head of the United Aircraft Corporation, said in 2013 that the PAK FA and the FGFA would use "identical onboard systems and avionics".

By 2014 the Indian Air Force began voicing concerns over performance, cost and workshare, and over stealth limited to the frontal 60-degree arc and the lack of supercruise, which narrowed the advantage over fourth-generation fighters. India refrained from signing a deal citing shared manufacturing, technology and maintenance concerns, and ultimately withdrew from the programme in 2018 before any prototype was built.
