The Sukhoi Design Bureau of Moscow, Russia has developed the Su-47 (previously called the S-37 Berkut or Golden Eagle) fighter aircraft, which first flew in September 1997. Su-47 is in a forward-swept wing configuration and uses a highly unstable triplane (with three main lifting surfaces) aerodynamic configuration. The Su-47 was introduced in January 2000 and completed the first stage of flight trials in December 2001. The aircraft is operated by the Russian Air Force. In May 2002, Sukhoi was selected as prime contractor for the next-generation Russian PAK FA fighter programme. The PAK FA fighter aircraft will be a development of the Su-47 but without the forward swept wings. The first flight test of the PAK FA fighter aircraft is scheduled for 2010.

The design of the very high manoeuvrability prototype is based on the avionics and aerodynamics technologies developed for the Su-27 upgrade programme. Some of the systems and component designs from the Su-27, (the all weather supersonic fighter aircraft with Nato reporting name Flanker), have been used in the Su-47, for example the design of the canopy, landing gear, some of the avionics and the near-vertical tails. The Su-47 has extremely high agility at subsonic speeds enabling the aircraft to alter its angle of attack and its flight path very quickly, and it also retains manoeuvrability in supersonic flight. Maximum turn rates and the upper and lower limits on air speed for weapon launch are important criteria in terms of combat superiority. The Su-47 aircraft has very high levels of manoeuvrability with maintained stability and controllability at all angles of attack. Maximum turn rates are important in close combat and also at medium and long range, when the mission may involve engaging consecutive targets in different sectors of the airspace. A high turn rate of the Su-47 allows the pilot to turn the fighter aircraft quickly towards the next target to initiate the weapon launch. Su-47 Berkut (wallpaper 1).
