The Russian-Indian Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) has stealth capabilities and is based on the Russian T-50 prototype jet.
"As far as the fifth-generation [plane] is concerned, the work is underway. The first stage is complete. The second stage is being discussed. I think it will be completed in near future, the documents have been signed," Sergey Chemezov told a press conference.
The FGFA project came about following the signing of a Russian-Indian cooperation agreement on October 18, 2007.
The PAK FA is a single-seat, twin-engine jet fighter designed by the Sukhoi Design Bureau. Its unique features make it the best in its class among other similar aircraft in the world, and it is the first operational aircraft in Russian service to use stealth technology.
