@muminekf: The Sukhoi Su-47 Berkut (Russian: Сухой Су-47 «Беркут») (NATO reporting name Firkin), was a Russian experimental supersonic technology demonstrator developed by the JSC Sukhoi Company. A distinguishing feature of the aircraft was its forward-swept wing intended to give the aircraft increased agility and maneuverability. While serial production of the type never materialized and the configuration was not further pursued, the sole aircraft produced served as a technology demonstrator prototype for a number of technologies later used in the Su-35 as a fourth-generation fighter, and the Su-57 as a fifth-generation fighter. #Su47 #su47berkut #russia #fighterjet #russiaarmy #russiaairforce🇷🇺 #russianfederation #edit #fypppppppppppppp
