Instead of receiving advanced new engines, the first flightworthy examples of the Su-57 have been equipped with Saturn AL-41F1 turbofan engines, which were designed in the 1980s. For example, claims by UAC and Sukhoi figures that the Su-75 will be powered by a state-of-the-art engine recall similar claims about the Su-57. What Will the Su-75 Actually be Capable of?īased on the lackluster development of Russia’s Su-57 Felon to date, which is similarly pitched as a highly advanced next-generation stealth fighter, it is unclear how a similarly ambitious project designed by the same design bureau, produced by the same aircraft conglomerate, and affected by the same punishing sanctions from the West would fare any differently.
According to Dmitri Shugaev, the Director of Russia’s Federal Service for Military-Technical Cooperation, Russia’s defense industry envisions the Checkmate being sold to customers in the Middle East, East Asia, and Latin America. The aircraft is reportedly designed to be capable of carrying modern Russian air-to-air, air-to-surface, anti-raditation missiles, as well as guided and unguided bombs, and is supposedly designed primarily for export as well.
UAC head Yuri Slyusar has claimed that the Su-75 will see its first flight in 2023, although little information by on progress made on the aircraft has been made available to external observers. Russian media have claimed that it will posses a single rotary nozzle jet engine, which appears to be located at the base of the Checkmate’s V-shaped tail in the few photos available of the mockup of the aircraft unveiled at the 2021 MAKS show. F-35 stealth fighter, which he called its main selling point.
Chemezov has also claimed that the per-hour cost of flying the Su-75 will be seven times cheaper than the U.S. According to Sergei Chemezov, the CEO of Rostec (Russia’s state-owned defense company which controls the United Aircraft Corporation and in turn Sukhoi), the Checkmate will have a range of roughly 1,800 miles without external fuel tanks, and a maximum combat load of more than 16,500 pounds. What Does Russia Claim the Su-75 Checkmate is Capable of?Īs a starting point, it is important to understand the capabilities the Su-75’s designers in the Sukhoi test bureau claim the aircraft will have. It is clear that Russia hopes to make the Checkmate into a fighter that will compete with state-of-the-art aircraft in service with Western air forces, but clear limits on Russian production capabilities and technological know-how could present insurmountable headwinds to such a goal. While the on-paper characteristics of the Su-75 seem impressive, it is yet to be seen if reality lines up with Russia’s plans. Russia’s Su-75 Checkmate Stealth Fighter Has a Problem: Ever since it was first unveiled at the 2021 MAKS Airshow near Moscow, significant speculation has emerged about the capabilities of the Su-75 stealth fighter, which remains in an early stage of development.
