Sukhoi Su-57, Russia’s newest fighter jet, entered service with Russian Aerospace forces.
One serial jet was transferred to the military in late November 2020, according to an anonymous source quoted by Russian state news agency TASS.
According to Rostec CEO Sergey Chemezov, ten pre-production prototypes were transferred to the Air Force as well.
It is Russia’s first fighter jet of the fifth generation, as well as its first stealth aircraft. It is intended to rival the Lockheed-Martin F-22 Raptor, the Lockheed-Martin F-35 Lightning II and the Chengdu J-20, wielded by NATO and Chinese militaries.
The prototype of Su-57 first flew in 2010. The first serial production aircraft was completed in 2019, but crashed later the same year.
Four more Su-57s are to be built and delivered in 2021. In total, Russian Air Force (a branch of Russian Aerospace Forces) is set to receive 76 new jets by 2027.
