![]() ![]() As the head of the UAC, Yuri Slyusar, explained after the presentation, the new fighter has the largest internal fuselage compartments for its class, which allows it to accommodate the entire range of Su-57 weapons.īetween its general shape, single-engine configuration, and even the computerized logistics system – dubbed ‘Matryoshka’ after the famous Russian nesting dolls – the new jet has drawn comparisons to Lockheed Martin’s F-35 Lightning II joint strike fighter. Moreover, the unique electronic warfare system "will not allow the enemy to use weapons". He is capable of destroying fifth-generation aircraft in both long-range and close air combat. Even when the enemy is outnumbered, he is ready to effectively fight for air superiority. Thanks to its active phased array radar, the Checkmate is capable of simultaneously attacking up to 6 targets, even in conditions of strong electronic interference. Low radar signature and an advanced complex of passive aviation weapons allow it to quietly go out to a distance for guaranteed target destruction. The tail planes featured are outward-canted, believed to be all-moving, and cover the role of vertical and horizontal planes seen in more conventional fighter designs. The wings are of relatively small-area delta shape. The fighter is to be equipped with a modern engine with a deflected thrust vector, has a shortened take-off and landing distance, and can instantly react to a changing combat situation. The engine exhaust at the rear of the fuselage is circular, with thrust vector control features. The rather small ventral diverterless supersonic inlet (DSI) allows clean air intake to the turbofan within the middle-aft of the fuselage (the Lockheed F-16 "Fighting Falcon" and Eurofighter "Typhoon" multirole types both feature this design), as did the Boeing X-32 prototype strike fighter which unsuccessfully competed with the F-35 Lighting II design. ![]() This means that this aircraft can be used to gain air control and target enemy ground targets. The display near this aircraft said that the R-73 anti-air missile, R-77 anti-air missile and KH-59MK anti-ship cruise missile will be installed in the Checkmate fighter jet. The fuselage is deep, tapered at the nose and tail, housing small lateral weapons bays for single SRAAMs and a single larger ventral weapons bay with 3 MRAAMs. This engine is made on the basis of the groundwork of the United Engine Corporation, and will be even more advanced on this aircraft," said Alexey Bulatov, Deputy Chief Designer of Checkmate, during the presentation of the machine. "The engine will be in the 14.5-16 t class. The vehicle will be equipped with a highly efficient power plant. The fighter will be able to simultaneously hit up to six targets. The payload weight will exceed more than seven tons. It can be equipped with a full range of weapons of the range of aviation weapons, which is equipped with the fifth generation Su-57 fighter. Its speed will be Mach 1.8 and the combat radius is 3,000 km. The aircraft can be equipped with five air-to-air missiles. During the MAKS2021 presentation, a number of characteristics of the newest machine were announced. The Sukhoi Checkmate LTS is a single-seat, single-engine configuration with a the cockpit a short nosecone, presumably shrouding an AESA radar unit. The aircraft’s performance in terms of stability, control, and high-angle-of-attack are improved by these changes, together with the enlarged strake flaps.Sukhoi Su-75 Checkmate - LTS - Light Tactical Aircraft - Design The aft strakes, which are lateral aerodynamic surfaces on the fuselage’s back, have also been expanded. This stealth capability allows the Su-75 to penetrate hostile airspace with reduced risk of detection, enabling it to carry out precision strikes and other missions with a higher chance of success. The aircraft incorporates a reduced radar cross-section, advanced composite materials, and optimized shaping to minimize its visibility to enemy radars. One of the key aspects of the Su-75 Checkmate is its stealthy design. This enhancement increases control authority and allows for precise maneuvering in a variety of flight modes. The flaperon, a control surface positioned on the wing, has been significantly enlarged and extended towards the back of the aircraft. Additionally, the wing root form has been modified to optimize airflow and minimize drag, resulting in improved maneuverability and overall efficiency. ![]()
