UCAV S-70 «Okhotnik-B» Stealth heavy unmanned combat aerial vehicle. The aerodynamically designed “flying wing” designed by the Sukhoi design bureau, with a landing gear retractable in flight.

The UAV is designed using stealth technology, its take-off weight is 20-22.000 kg (according to other data 25.000 to 30.000 kg).

All the weapons of the “Hunter” are located / transported by internal compartments, which makes it possible to carry various types of missiles, including guided bombs.

The landing gear of the UAV are identical to the design of the Su-57, it is obvious that the UAV was developed on the basis of the Su-57.

The first prototype of the new UCAV S-70B "Okhotnik" was presented on December 14/2021. The "Okhotnik" is the latest version of the S-70B incorporating a new design and new advanced electronic systems. To achieve low visibility (stealth) the aerial mean has a trapezoidal design nozzle which was designed and printed on a 3D printer. The unmanned vessel developed to accompany the Su-57 Felon (which will be controlled and coordinated by the crews).
