Sukhoi (part of Rostec State Corporation’s United Aircraft Corporation) has patented its newest stealth fighter, the Su-75 ‘Checkmate’.
The patent confirms that the Russian-design aircraft is superior to known foreign analogs in terms of both flight and field performance, Rostec said in a statement.
“In addition, Russian designers have improved the Checkmate’s stability and control while maintaining its high aerodynamic performance and stealth characteristics. The new patent also states that the Checkmate’s engine can be fitted with a thrust vectoring nozzle moving in the vertical plane that is aligned with the aircraft body axis and is used for flight control and trimming,” the statement added.
A prototype of the fifth-generation Checkmate fighter jet was first unveiled last July at the MAKS-2021 air show.
The single-engine Su-75 Checkmate is designed to be a low-cost alternative to the US’ F-35 fighter jets. This modern aircraft is the second fifth-generation warplane that Russia will produce after the Su-57 ‘Felon’.
An earlier presentation by Rostec at the MAKS-2021 air show revealed that Su-75 will have the capability of carrying a group of drones on board. Additionally, it would carry more than seven tons of payload.
The fighter would be capable of striking up to six targets simultaneously. There is speculation Checkmate will be powered by a derivative of the NPO Saturn AL-41 engine, which is also installed on Su-57. It will have a maximum speed of Mach 1.8 and supercruise performance. The single-engine aircraft will have a combat radius extending up to 3,000 km.
The aircraft has reportedly been designed with customers such as Vietnam, India, and African countries in mind.
In January 2022, The EurAsian Times reported that Russia is looking to co-produce the Checkmate stealth fighter jet with the United Arab Emirates (UAE), which had suspended a $23 billion arms deal with the US.
Reports stated that Moscow and Abu Dhabi were in talks to co-produce the required composite materials and communications technology for the Su-75. However, there has been no update on this since then, probably due to Russia’s tensions and subsequent war with Ukraine.
