The Sukhoi S-70 Okhotnik-B, also known as the Hunter-B, is a Russian heavy unmanned combat aerial vehicle (UCAV) designed by Sukhoi and Russian Aircraft Corporation MiG. It is claimed to be a sixth-generation fighter using stealth technology.
2. How was the Okhotnik-B developed?
The Okhotnik has been under development since at least 2011, when Sukhoi was selected by the Russian Defense Ministry to lead a programme for a new heavy unmanned reconnaissance and attack drone. The new UCAV is being jointly developed by MiG and Sukhoi, based on data from the earlier Mikoyan Skat UCAV programme.
3. What are the key design features of the Okhotnik-B?
The Okhotnik's design is based on the flying-wing scheme and incorporates use of composite materials and stealth coatings, reducing the drone's radar cross section in flight. It has a weight of about 20 tons and a wingspan around 65 feet (20 m). The drone is powered either by a single AL-31F turbofan or by the improved AL-41F derivative installed on Su-35S fighters and Su-57 prototypes.
4. What was the maiden flight of the Okhotnik-B like?
The Okhotnik performed its maiden flight on August 3, 2019. The drone flew for about 20 minutes at an altitude of 600 meters above Chkalov State Flight Test Center in Akhtubinsk, making several circles around the airfield. The Russian Defence Ministry released a video of the first flight on August 7, 2019.
5. How has the Okhotnik-B been tested and used?
The Okhotnik has undergone various tests, including carrying out strikes with unguided weapons in 2021 and precision-guided munitions in 2022. In August 2023, it was reported that state tests for the Okhotnik will be completed by the end of 2023, with the drone expected to enter mass production in 2024.
6. What happened to the Okhotnik-B recently?
A rare Russian stealth drone, the Sukhoi S-70 Okhotnik-B, was reportedly shot down near Kostyantynivka in the Donetsk region, Ukraine. The incident marks a significant loss for Russian military forces in the ongoing conflict. The cause of the downing is unclear, with conflicting reports suggesting either friendly fire or Ukrainian air defense systems.
7. What are the implications of the Okhotnik-B's development and deployment?
The Okhotnik represents a major advancement in Russia's military drone capabilities. It is designed to perform various combat tasks, including reconnaissance and strike missions, with stealth as one of its defining features. The incident highlights the need for refinement in its electronic warfare capabilities and stealth features when facing modern air defenses.
