Overview
The Sukhoi Su-75 Checkmate is a single-engine stealth fighter being developed as a lightweight, affordable 5th-generation combat aircraft. Unveiled at MAKS 2021, it is designed for both domestic use and export to compete with the F-35.
Design & Development
The Su-75 features a single-engine stealth design with V-tail, internal weapons bays, canted vertical stabilizers, and a DSI (diverterless supersonic inlet). It uses a single AL-41F1 engine — the same powerplant used in the twin-engine Su-57. The design emphasizes affordability and low operating costs.

The program’s timeline is uncertain given Russia’s current geopolitical and economic constraints.
