Su-75 Checkmate: Russia’s Next-Gen Stealth Fighter

The Sukhoi Su-75 “Checkmate” represents Russia’s newest foray into fifth-generation stealth fighter design. Developed by Sukhoi under the United Aircraft Corporation (UAC), the Su-75 aims to deliver a cost-effective alternative to Western jets like the F-35 Lightning II and Rafale. First unveiled at the MAKS 2021 Air Show, the single-engine stealth jet is designed primarily for export markets seeking next-gen performance at reduced acquisition costs.

Built with a focus on stealth, affordability, and modularity, the Su-75 incorporates low radar cross-section shaping, internal weapons bays, and AI-assisted mission systems. The aircraft is projected to reach Mach 1.8, with a combat radius exceeding 1,500 km, making it suitable for long-range interdiction, air superiority, and ground-attack missions.

The Su-75’s avionics suite is expected to feature an AESA radar, sensor fusion, and advanced electronic warfare (EW) capabilities comparable to fifth-generation standards. Its cockpit design emphasizes digital integration, featuring a large multifunction display and helmet-mounted sight system.

The aircraft’s modular design allows future variants, including unmanned or twin-seat versions, supporting a wide range of mission profiles. UAC has positioned the Su-75 as a viable export solution for nations unable to access Western platforms due to political or financial barriers.

Su-75 Checkmate Price in US

The Su-75 Checkmate’s estimated price in the United States market—if hypothetically available—is projected around $30–35 million per unit, making it one of the most affordable fifth-generation fighters. Actual export pricing will depend on configuration and buyer requirements once production begins.
