DefenseThe new Russian Sukhoi Checkmate stealth fighter should feature engines equipped with a vectorable exhaust nozzle, a source told Ria Novosti.
The 5th generation fighter aircraft was unveiled in July 2021 during the MAKS air show as an export-focused project.
Because of this, the Checkmate is only equipped with an afterburner engine, a configuration that the Russian Air Force did not accept years ago.
According to the website, the mouthpiece would originally only move vertically, but patents filed in Russia show a device that moves in all directions. The configuration will allow the fighter greater maneuverability, as well as more efficient take-off and landing performance.
This type of equipment is used in other Russian fighters such as the Sukhoi Su-30M and Su-57, from which the Checkmate takes advantage of several components.
New engine on the way
Already the website Aviation 21 points out that the fighter, which may receive the designation Su-75, will have a new engine in the future. Currently, the supersonic jet is believed to be equipped with the AL-41F1 turbofan, used by the Su-57, for cost savings.
Apparently, however, the Checkmate will also have the Izdelie 30 engine, a project created from scratch and that has been tested for a few years with the promise of being more powerful, lighter and with a more modern concept.
In May, Rostec, Russia's state-owned technology company, said the new fighter should go into production only in 2027.
