09.11.2021
The Sukhoi Su-47 Berkut (Firkin), also designated S-32 and S-37 during initial development, was an experimental supersonic jet fighter developed by the J-S-C Sukhoi Company. A distinguishing feature of the aircraft was its forward-swept wing that gave the plane excellent agility and maneuverability. While serial production of the type never materialized, the sole aircraft produced served as a technology demonstrator prototype for several advanced technologies later used in the 4.5 generation fighter Su-35 and current fifth-generation jet fighter Su-57.
