Sukhoi SU-47 Berkut

The Su-47 Berkut is an experimental supersonic jet fighter developed by Sukhoi, notable for its distinctive forward-swept wing design. This unique configuration aimed to improve maneuverability at high angles of attack and enhance short take-off and landing capabilities. Although it never entered full production, the Su-47 served as a valuable technology demonstrator, influencing the development of subsequent Russian fighter aircraft.
