Sukhoi S-70 Okhotnik-B

The Sukhoi S-70 Okhotnik-B, meaning Hunter-B, is a Russian stealth heavy unmanned combat aerial vehicle being developed by Sukhoi and the Russian Aircraft Corporation MiG. It is based on the earlier Mikoyan Skat and includes technologies from the fifth-generation Su-57 fighter, and was projected to operate under the control of Su-57 pilots in a future version. Sukhoi was chosen by the Russian Defence Ministry in about 2011 to lead the programme, and the work is done at the Novosibirsk Aircraft Production Association. The first mock-up came in 2014, the flying-wing prototype was shown in July 2017, and it made its maiden flight on 3 August 2019, flying about 20 minutes at 600 metres. Prototypes were tested from 2019 to 2023, production was projected for 2024, and an out-of-control S-70 was shot down by a Russian Su-57 over Ukraine in October 2024.
