Russia Su-47
Su-47 / test flight

While not intended to be developed into a battle-ready, fully functional military fighter, the Su-47 (also designated S-35 and S-37) incorporates several original and potentially important features that bear close watching. Much of what is learned from the test flights of the Su-47 will be incorporated into Russia's production of new fifth-generation aircraft. The Su-47 Berkut (Golden Eagle) transitioned to white status in January 2000. One aircraft has been built at a cost estimate of Russian rubles 1.67 billion ($70 million).
Innovative features of the Su-47 include: an aluminum / titanium fuselage whose components are 13% state-of-the-art composite materials and sophisticated fly-by-wire control. Forward swept and inverted wings allow for exceptional maneuverability and attack angles up to 45°. The quick turn ability of the Su-47 may have no equal. Lower minimum flight speed allows for use of short runways. Thrust vector engines of +/ 20 to 30 degrees/second further enhance the maneuverability capacity that derives from the high angle inverted wings. Its maximum speed is Mach 2.34 (2,500 km/h, 1,552 mph), range is 3,300 km (2,050 mi), ceiling is 18,000 m (59,050 ft) and rate of climb is 233 m/s (46,200 ft/min).
