The Sukhoi S-70 Okhotnik (Russian: Сухой С-70 "Охотник", lit. 'Hunter'), also referred to as Okhotnik-B.
Sukhoi S-70 Okhotnik
The Okhotnik has been under development since at least 2011, when Sukhoi was selected by the Russian Defence 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 of the earlier Mikoyan Skat UCAV programme. The work is carried out by the Novosibirsk Aircraft Production Association (NAPO), part of the Sukhoi company. In the documents, the drone is characterised as a "sixth-generation unmanned aerial vehicle".
The first mock-up intended for ground tests was created in 2014. Prototype of the drone was first revealed in July 2017, showing the drone's flying wing configuration.
In November 2018, the drone performed first series of taxiing, speeding and stopping tests in fully autonomous mode at a runway of the NAPO plant. During the runs, it has reached a maximum speed of 200 km/h.
On 18 January 2019, the third flyable Su-57 prototype (bort no. 053) was spotted wearing a new digital camouflage paint scheme, with digital silhouette of the Okhotnik on its top and underside and a unique markings on the vertical tail showing the shape of a UCAV flying alongside the shape of Su-57 with a lightning bolt (universally used to show electronic connectivity and data sharing) between the two. On 24 January 2019, first flyable prototype of the drone was seen towed at the NAPO plant. According to Russian officials, the Su-57 is being used as a flying laboratory for the testing of the Okhotnik's onboard radio-electronic systems, namely avionics

The Okhotnik's design is based on the flying-wing scheme and incorporates use of composite materials and stealth coatings, making the drone low-observable 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, as used on the Sukhoi Su-27 fighter aircraft, or by the improved AL-41F derivative installed on Su-35S fighters and Su-57 prototypes. Although the first prototype's exhaust nozzle was conventional and thus degrading its low observable features, future upgrade could see improved exhaust as well as engine inlet as shown by a mock up during 2019 edition of MAKS.
