2024年上半年，俄罗斯苏霍伊公司宣布其新一代轻型隐身战斗机苏-75（Checkmate）完成首飞。作为俄罗斯首款面向出口市场的第五代单发战斗机，苏-75在设计上强调高机动性、隐身能力和成本效益。其采用单发AL-41F或未来可能换装的“产品30”发动机，最大起飞重量约18吨，作战半径可达3000公里，具备超音速巡航能力。武器系统方面，苏-75拥有内部弹舱，可携带空对空导弹、精确制导炸弹等，兼顾空优与对地打击任务。尽管其隐身性能可能略逊于F-35等西方同类机型，但凭借较低的采购与维护成本，以及模块化设计带来的升级灵活性，苏-75有望在国际军贸市场吸引预算有限但寻求现代化装备的国家。总体来看，苏-75填补了俄制战机在轻型五代机领域的空白，是俄罗斯航空工业在高端出口市场的重要布局。
In the first half of 2024, Russia’s Sukhoi Company announced the successful maiden flight of its new-generation light stealth fighter, the Su-75 ‘Checkmate.’ Designed as Russia’s first fifth-generation single-engine fighter targeting the export market, the Su-75 emphasizes high maneuverability, stealth capabilities, and cost-effectiveness. Powered by a single AL-41F engine—with potential future upgrades to the ‘Izdeliye 30’—the aircraft has a maximum takeoff weight of approximately 18 tons, a combat radius of up to 3,000 kilometers, and supercruise capability. It features an internal weapons bay capable of carrying air-to-air missiles and precision-guided munitions, enabling both air superiority and ground attack roles. While its stealth performance may not match that of Western counterparts like the F-35, the Su-75’s lower acquisition and maintenance costs, combined with a modular design that allows for flexible upgrades, make it attractive to budget-conscious nations seeking modern combat aircraft. Overall, the Su-75 fills a critical gap in Russia’s fighter portfolio and represents a strategic move to strengthen its position in the global defense export market.
