The Sukhoi Su-75 Checkmate is a single-engine, stealth fighter aircraft under development by Sukhoi for export and for the Russian Aerospace Forces.
The Sukhoi Design Bureau also designates the aircraft as T-75 with marked registration RF-0075.
The Su-75 Checkmate has a diverterless inlet, a v-shape tail and internal weapons bays—all features intended to reduce radar signature. The wing area appears large, which has been interpreted by correspondent David Axe to imply that Sukhoi designed the fighter to fly and engage in combat at high altitudes—40,000 feet or higher.
