Overview

The S-70 Okhotnik, meaning Hunter-B, is a flying-wing UCAV about 14 m long with a 19 m wingspan and a maximum take-off weight of about 20 tonnes, per Russian officials, and unverified. It first flew on 3 August 2019 at Novosibirsk, and on 27 September 2019 it flew in public alongside a Su-57. The first prototype used an AL-31F-type engine with a flat nozzle, and a purpose-built engine is planned for serial production. It is designed as a loyal wingman for the Su-57 with AI-assisted control.

Claimed performance is a speed up to about 1,000 km/h, a range of about 6,000 km and around 2.8 tonnes of internally carried payload. The Russian Ministry of Defence ordered a first batch in 2018, and officials repeatedly announced serial production for 2024 to 2025, but only a few airframes exist and deliveries are not confirmed. Reports in late 2024 claimed the S-70 flew in combat in Ukraine, but these are unconfirmed and rest on Russian and Ukrainian media. No loadout list is public.
