Sukhoi Su-75 Checkmate

A static non-flying prototype was unveiled at the 2021 MAKS air show with President of Russia Vladimir Putin in attendance. The Checkmate's maiden flight was first scheduled for 2023 and then slipped to 2024 but then it got delayed to 2025,{{Cite web |title=Борисов сообщил о переносе сроков первого полета Су-75 Checkmate — РБК |language=ru |trans-title=Borisov Announces Postponement of Su-75 Checkmate First Flight |author-last=Demchenko |author-first=Natalia |website=RBK Group

In July 2023, analyst Maya Carlin of the Center for Security Policy wrote that sanctions against Russia, due to the ongoing invasion of Ukraine had slowed or stopped the aircraft's development. In particular noted was the loss of funding from the United Arab Emirates due to sanctions, which had been sustaining the Su-75's development, as the UAE seeks instead to acquire F-35s, with potential support from Israel.{{cite web|url= https://bulgarianmilitary.com/2023/07/28/nigeria-is-interested-in-the-su-75-which-is-in-the-prototype-stage/|title= Nigeria is interested in the Su-75, which is in the prototype stage|access-date= 30 July 2023|last= Lenkov|first= Alexey|work= bulgarianmilitary.com|date= 28 July 2023|archive-url= https://archive.today/20230730121403/https://bulgarianmilitary.com/2023/07/28/nigeria-is-interested-in-the-su-75-which-is-in-the-prototype-stage/|archive-date= 30 July 2023|url-status= live}}

The Su-75 has a diverterless supersonic inlet (DSI), a v-tail and internal weapons bays—all features intended to reduce radar signature. 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—{{cvt|40000|ft|m}} or higher.{{Cite web|last=Axe|first=David|title=Who's Going To Pay for Russia's Checkmate Stealth Fighter?

However, ruddervators require more sophisticated flight-control systems than conventional empennages.

According to the jet's designers, the Checkmate is designed to fly with a range of up to {{convert|3000|km|mi|0|abbr=on}}, carry a payload of up to {{convert|7400|kg|lb|0|abbr=on}}, and reach speeds of up to Mach 1.8 to 2.0.{{Citation|title=Official presentation of the New Sukhoi LTS Checkmate or Screamer|date=2021-07-20|url=https://www.youtube.com/watch?v=akFigd3UDXE|website=YouTube.com|archive-url=https://web.archive.org/web/20210721153623if_/https://www.youtube.com/watch?v=akFigd3UDXE|language=en|access-date=2021-07-25|archive-date=2021-07-21|url-status=live}}{{Cite web |author-last=Šerzad |author-first=Timur |date=July 20, 2021 |script-title=ru:Раскрыты характеристики новейшего однодвигательного истребителя «Сухого» |trans-title=The characteristics of the latest single-engine Sukhoi fighter are revealed |url=https://tvzvezda.ru/news/20217201539-triew.html |url-status=live |archive-url=https://web.archive.org/web/20210720133636/https://tvzvezda.ru/news/20217201539-triew.html |archive-date=20 July 2021 |access-date=29 April 2023 |website=Zvezda (TV channel) |language=ru}} The fighter will also feature an internal weapons bay with five missiles and an autocannon.{{Cite web|title=YouTube|url=https://www.youtube.com/watch?v=Gc2l8xWau60|archive-url=https://web.archive.org/web/20210720205532/https://www.youtube.com/watch?v=Gc2l8xWau60&gl=US&hl=en|url-status=dead|archive-date=20 July 2021|website=www.youtube.com}}

Patents published in 2023 indicate that the initial design had been modified with changes to the fuselage sides, strakes and the air intakes to reduce radar signature. Mainly, the new design appears to have increased the lifting surface area of the airframe.

Due 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. 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. The cockpit has a wide-angle (30° by 22°) head-up display (HUD).{{Citation|title=Russia Unveils New Fighter Jet Viewed As Competitor To America's F-35|url=https://www.youtube.com/watch?v=Tf-3HcikmzE|language=en|access-date=2021-07-30 |website=YouTube.com |publisher=NBC News |date=2021-07-26 |archive-url=https://web.archive.org/web/20210727145313if_/https://www.youtube.com/watch?v=Tf-3HcikmzE |archive-date=2021-07-27 |url-status=live}}

The electronic infrastructure of the Checkmate is all open-architecture and makes use of "Matryoska" diagnostics systems that are mostly on-board. According to Yuri Beliy, the NIIP radar design bureau plans to develop a low-cost AESA radar for the aircraft. According to then-Deputy Prime Minister Yury Borisov, the Checkmate will share the same components and avionics as the Su-57 as a cost-reduction mechanism by the Sukhoi Design Bureau.{{Cite news |script-title=ru:Чемезов назвал цену нового российского истребителя |trans-title=Chemezov called the price of the new Russian fighter |url=https://www.vedomosti.ru/technology/news/2021/07/20/878918-chemezov-nazval-tsenu-novogo-rossiiskogo-istrebitelya |url-status=live |archive-url=https://web.archive.org/web/20211019025855/https://www.vedomosti.ru/technology/news/2021/07/20/878918-chemezov-nazval-tsenu-novogo-rossiiskogo-istrebitelya |archive-date=19 October 2021 |access-date=2021-10-19 |website=Ведомости |language=ru}}{{Cite news |date=20 July 2021 |script-title=ru:Новый российский истребитель Checkmate поднимется в воздух в 2023 году |trans-title=The new Russian fighter Checkmate will take to the air in 2023 |url=https://www.vedomosti.ru/business/news/2021/07/20/878934-novii-rossiiskii-istrebitel-checkmate-podnimetsya-v-vozduh-v-2023-godu |url-status=live |archive-url=https://web.archive.org/web/20211019025853/https://www.vedomosti.ru/business/news/2021/07/20/878934-novii-rossiiskii-istrebitel-checkmate-podnimetsya-v-vozduh-v-2023-godu |archive-date=19 October 2021 |access-date=19 October 2021 |website=Ведомости |language=ru}}
