Sukhoi aims to export 300 Su-75 Checkmate aircraft to African countries over the next 15 years. Rostec is anticipating that Argentina, India and Vietnam will become the primary export destinations for the aircraft, with the African market also showing interest. VariantsĪn unmanned variant is reportedly in development, a two-seat trainer version can be developed if requested, and a carrier-based version is also under consideration. The Rostec chief executive said in an interview with The Wall Street Journal that the Su-75 fighter will carry more than 7 tonnes of air-to-air and air-to-surface armaments and will be capable of striking several targets at a time.

According to Deputy Prime Minister Yuri Borisov, the Checkmate will share the same components and avionics as the Su-57 as a cost-reduction mechanism by the Sukhoi Design Bureau. According to Yuri Beliy, NIIP radar design bureau plans to develop a low-cost AESA radar for the aircraft. According to Russian newspaper Top War, the prototype Su-75 is built with an active phased array radar. The electronic infrastructure of the Checkmate is all open-architecture and makes use of "Matryoska" diagnostics systems that are mostly on-board. The cockpit has a wide-angle (30° by 22°) head-up display (HUD). According to Bodner, the cockpit layout is identical to the Su-57 with a glass cockpit with two 38 cm (15 in) main multi-functional LCD displays similar to the arrangement of the Su-35S. Cockpitĭue to restrictions preventing taking cockpit photos, NBC News Matt Bodner, the first Western journalist able to see the jet in person, provided a preview without a point of view photo.

Once in series production, the izdeliye 30 engine will have a much longer life span than other Russian engines. The izdeliye 30 is designed to be 30% lower specific weight than its AL-41F1 predecessor, and up to 18% more effective, with an estimated thrust of 107.9 kN (24,300 lbf) dry and 171.7 kN (38,600 lbf) in afterburner. The powerplant appears to be the Saturn izdeliye 30 engine which will also power the Su-57M variant. The fighter will also feature an internal weapons bay with five missiles and an autocannon. Īccording to the jet's designers, the Checkmate is designed to fly with a range of up to 3,000 km (1,864 mi), carry a payload of up 7,400 kg (16,314 lb), and reach speeds of up to Mach 1.8 to 2.0. However, ruddervators require more sophisticated flight-control systems than conventional empennages. Instead of a set of elevators and a tail separately controlling pitch and yaw, a pair of combined ruddervators fulfil both roles. Instead of a conventional empennage, the Su-75 fighter has a V-tail similar to that of Northrop YF-23. A diverterless supersonic inlet (DSI) is mechanically simple DSI can reduce cost compared to more intricate inlet designs such as the McDonnell Douglas F-15 or Sukhoi Su-27. The angular ventral inlet, which wraps around the lower nose section, shares features with a DSI design concept first introduced in the Boeing X-32 aircraft. The wing area appears large, which has been interpreted by correspondent David Axe to imply that Sukhoi designed the fighter to fly and engage in combat at high altitudes-40,000 ft (12,000 m) or higher. The Su-75 Checkmate has a diverterless supersonic inlet (DSI), a v-tail and internal weapons bays-all features intended to reduce radar signature. On 16 August 2022, United Aircraft Corporation reported that they plan to build four prototypes of the Su-75 Checkmate, with flight tests planned for as early as 2024. The potential export sales also stalled because Russia cannot trade using U.S.
Su-75 Checkmate development could be delayed due to international sanctions on Russia, and Russia could not import semiconductors and high-tech machining equipment from the European Union. On 14 November 2021, it was reported that the production of several prototypes of the Checkmate had begun at the Komsomolsk-on-Amur Aircraft Plant, where the Sukhoi Su-57 is manufactured. Īccording to the chief executive of Rostec, Sergei Chemezov, the LTS Checkmate is expected to cost US $25–30 million each. Production is forecast to be 300 planes over 15 years. The Checkmate is designed to be low cost and for export, and may compete with the Lockheed Martin F-35 Lightning II and Shenyang FC-31 aircraft of the same light to medium-weight category. The Checkmate's maiden flight was first scheduled for 2023 and then slipped to 2024, with initial deliveries planned for 2026–2027. DevelopmentĪ static mock-up was unveiled at the 2021 MAKS air show with President of Russia Vladimir Putin in attendance. The Sukhoi Design Bureau also designates the aircraft as T-75. The Sukhoi Su-75 Checkmate ( Russian: Сухой Су-75 LTS, short for Light Tactical Aircraft in Russian) is a single-engine, stealth fighter aircraft under development by Sukhoi for export and for the Russian Aerospace Forces.
