PAK FA T-50 received the official designation – Su-57

The commander-in-chief of the Russian Air Force, Victor Bondarev, in an exclusive interview to the site of the Zvezda television channel, officially announced the serial name of the fifth-generation fighter T-50 for the first time. The aircraft received the designation Su-57.

Su-57 (factory index T-50) is the fifth-generation Russian fighter developed by Sukhoi Design Bureau in the framework of the PAK FA project (a promising aviation complex for front-line aviation). Work on the aircraft began in 2002.

The first flight of the T-50 took place on January 29, 2010, and the following year, in the course of flight tests, the fighter overcame the sound barrier.

Most of the information on the Su-57 is classified, so only approximate characteristics of the aircraft are known. It is known that it has the latest on-board electronics, a radar, a glider created with the use of composite materials, and pilots of the fighter will receive a new flying suit and helmet.

At the MAKS-2017 airshow, the head of the United Aircraft Corporation Yury Slyusar said that the first stage of testing the aircraft is completed, and its serial shipments will begin in 2019. The installation lot of the fighters will be 12 cars.

Variants-

The completed joint Indian/Russian versions of the single-seat or two-seat FGFA will differ from the current T-50 flying prototypes in 43 ways with improvements to stealth, supercruise, sensors, networking, and combat avionics.

Russia was the only country for India that transferred all technologies without restrictions, declared Sergei Chemezov, the CEO of Rostec, to the Indian media.

“Stage 1 is over. Now we are discussing the 2nd stage. And I think that in the near future all decisions will be made. And the contract documents will be signed. But the work is going, it is very complicated, so it is not going fast.”
