Russian designers have completed work on the documentation necessary for the production of the first examples of light fifth-generation fighters Su-75 Checkmate (Check and mate - note of the www1.ru editors), according to Rostech.

The plane was first presented to the public in 2021 at the air show in Dubai. Foreign customers studied the aircraft and made their suggestions for its improvement. As noted in the state corporation, on their basis individual technical solutions were adjusted, which affected the cost of the aircraft. This significantly increased the competitiveness of Checkmate. 

The press service of Rostech clarified that the development of the single-engine Su-75 Checkmate was carried out at Sukhoi Design Bureau (part of UAC). It is noted that the Checkmate version has a high degree of unification with the twin-engine Su-57.

Fighters with a single engine are smaller in dimensions, cheaper and more economical in terms of maintenance. They can be used for pilot training, as well as for combat missions.

Earlier it was reported that the use of Su-35 by Russian pilots in combat operations caused concern in NATO.
