The three vehicles of Yakovlev Proryv family: reconnaissance Proryv-R in the left, early warning Proryv-RLD on the right and the strike Proryv-U between them.

High-altitude long-endurance Oryol designed in the 1980s by the Yakovlev design bureau.

The final design of the Myasishchev M-62 Oryol is similar to Boeing's Condor all-bonded composite UAV which was flown in a 141-hour flight-test prgramme between 1988 and 1989.

Two radio-transparent fuselages of the Sukhoi S-62 fit side-looking radar antennas.

The Inokhodets is a research and development project intended to result in an unmanned aerial system ready for series production.
