Sukhoi S-70 Okhotnik-B

The Sukhoi S-70 Okhotnik-B is a heavy UCAV and low-observable flying-wing platform developed in Russia. Designed by Sukhoi, the system is intended to support reconnaissance, electronic warfare and precision-strike missions, while also contributing to a loyal-wingman concept capable of operating alongside manned combat aircraft.

Its tailless flying-wing airframe and use of radar-absorbent materials are intended to reduce radar visibility. Internal weapon bays allow munitions to be carried inside the airframe and support the platform’s low-observable design goals.

Okhotnik-B’s mission architecture emphasises AI-assisted target detection, autonomous flight, electronic attack and interoperability with manned aircraft such as the Su-57. Electro-optical, thermal and SAR-based payloads can support reconnaissance, target localisation and battlespace awareness.

Since the platform remains in development and testing, its final operational performance and production configuration have not been fully established in public sources. According to the Plarok database, the S-70 is recorded with a maximum speed of 540 knots, an approximate range of 6,000 kilometres, a service ceiling of 40,000 feet and a payload capacity of 2,800 kilograms. Endurance remains listed as TBC because no confirmed public value is available.
