Russia's newest light tactical fighter Checkmate will use the same engine as the Su-57, Rostec CEO Sergey Chemezov said
"Why were we able to make this aircraft so quickly? We used the Su-57 developments. ... This is both the engine and avionics," Chemezov told reporters at the MAKS-2021 air show.
Checkmate has one engine, the Su-57 has two.
