Media: “Sukhoi” is developing a single-engine fighter based on the Su-57 developments

The Sukhoi Design Bureau is working on a single-engine supersonic tactical fighter, TASS and RIA Novosti reported, citing industry sources. A TASS source notes that the development of the fifth generation Su-57 fighter will be used to create the aircraft.

The Sukhoi single-engine fighter should have a take-off weight of up to 18 tons, achieve a flight speed of more than Mach 2 and an aircraft thrust-to-weight ratio of at least 1, the agencies report. The aircraft is planned to be equipped with a radio-absorbing coating, airborne electronic equipment and a weapon system developed as part of the creation of the Su-57.

Among other developments of the Su-57, which are planned to be used in the creation of a new fighter, is called the “product 30” engine with a deflected thrust vector. At the stage of creating an experimental vehicle, according to RIA Novosti, the Al-31FN engine of series 3 and 4, already tested on foreign fighters, can be used.

Sukhoi (part of the United Aircraft Corporation Rostec) is developing the aircraft on its own initiative, RIA Novosti notes. Recall that in December 2020, Rostec CEO Sergei Chemezov reported that the state corporation, at its own expense, is working on a light single-engine fifth-generation fighter. Mr. Chemezov noted that Rostec is considering “various options for cooperation with foreign partners” (quote from RBC).
