Sukhoi Su-47 Berkut High Manoeuvrability Aircraft PhotosHighly Manoeuvrability and high angle of attack, the Su-47 Berkut (Eagle), initially known as the S-37, using a wing configuration to the sweep. The Su-47 completed the first stage of flight tests in December 2001.
Although the Russian aircraft was built as a testbed for the development of the fifth generation of technologies in May 2002, Sukhoi was selected as prime contractor for the agenda of the next generation Russian PAK FA fighter. Although the Su-47 is used for the PAK FA program, the design will probably be very different.
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. It also retains its great maneuverability in supersonic flight.
