India always remains in the running for new Russia fighter types as well while the Checkmate may very well be used as a lightweight counterpart to the heavier Su-57 for the Russian Air Force, as the Mikoyan MiG-29 "Fulcrum" has been to the Sukhoi Su-27 "Flanker" series for decades. Named prime candidates for the Checkmate appear to include Argentina and Vietnam who both field an aging feet of primary 4th Generation (or older) fighters. Additionally, base on the tail number on display, the fighter may carry the official designation of "Su-75" in service. It is accepted that the Checkmate aircraft on display at MAKS is a full-sized mockup and not a full-fledged, flyable prototype. As such, the Checkmate may feature performance and battlefield capabilities somewhere between this 5th and 4th (respectively) fighter designs. The F-16 Block 50/52 aircraft has a maximum speed of Mach 2.05 and a GTOW of 13.25 tons. Comparatively, the F-35 reaches speeds of Mach 1.6 at altitude and sports a gross weight of 25 tons. Gross Take-Off Weight (GTOW) is assumed to be in the 20 ton (short) region. The tailplanes featured are outward-canted, believed to be all-moving, and cover the role of vertical and horizontal planes seen in more conventional fighter designs.Įstimate performance figures indicate a maximum speed beyond Mach 2.0. The mainplanes are of relatively small-area delta shape, negating the need for traditional horizontal tailplanes. The exhaust port of the engine, bookended at the rear of the fuselage by the tailfins, is circular. The new fighter also bears some similarities to the Boeing X-32, a prototype strike fighter which unsuccessfully competed with the X-35 for the role eventually fulfilled by the F-35 Lighting II design. Interestingly, the air inlet is fitted ventrally, allowing for 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 quality). The fuselage is deep, tapered at the nose and tail ends, and assumed to house an internal weapons bay or bays. The cockpit is seated aft of a short nosecone, presumably shrouding an all-modern radar unit. The aircraft appears to borrow design lines from both the American Lockheed Martin F-35 "Lightning II" strike fighter and the Russian Sukhoi Su-57 "Felon" multi-role fighter, both featuring inherent stealth characteristics as well as 5th Generation classification.Īt its core, the fighter in question is of single-seat, single-engine configuration with proven external stealth characteristics including fuselage chine running from nose to tail. The design is sponsored by Rostek State Corporation (UAC) and was teased in the days leading up to the MAKS 2021 air show outside Moscow. and actually enters production.The Sukhoi "Chekcmate" 5th Generation lightweight stealth fighter is the latest combat aircraft offering from Russia, the entry viewed to be a low-cost, stealth-minded offering by Russia for interested export parties. Only time will tell if Checkmate beats the odds. Most new fighter designs never enter production, owing either to developmental problems or a dearth of paying customers. The Russian air force might also want to acquire Checkmates in order to complement its bigger, stealthier and likely very expensive Su-57s.Īll that said, Checkmate might not be ready to fly-especially if the thing appearing at MAKS is a mock-up rather than a functional demonstrator. It should come as no surprise, then, that Checkmate seems to include this kind of inlet.Īfter all, Sukhoi’s goal apparently is to develop a stealth fighter that foreign customers can afford. So if you’re going for an affordable, maneuverable fighter that also has low-observable qualities and you don’t mind sacrificing some speed, a DSI chin inlet is a smart approach. The main liability of a DSI is that it probably limits a jet’s top speed to slower than Mach two, whereas complex side inlets can produce top speeds exceeding Mach two. ![]() ![]() ![]() As a bonus, a DSI is mechanically simple, so it can drive down cost compared to more intricate inlet designs such as those on the American F-15 and Russian Su-27. They slow the incoming air and obscure the turbine. The shaping and underbite on a DSI achieves two things. And Lockheed Martin in the 1990s refined a new inlet design-a so-called “divertless supersonic inlet,” or DSI-that includes carefully-placed bumps and bulges as well as that distinctive underbite. That said, the Eurofighter consortium reportedly found a way to snake the Typhoon’s inlet in order to obscure the turbine. ![]()
