Sukhoi PAK-FA or T-50

Sukhois PAK-FA or T-50 is started taxi trials in December 2009 and first flight 29 January 2010. Designed by Sukhoi and built by the companys Komsomolsk-on-Amur Aviation Plant, the T-50 prototype flew for 47 minutes and landed on the plants airfield.

According to Sukhoi, the fighter Russias first all-new warplane since the collapse of the Soviet Union ? has new avionics systems, a phased-array radar, and equipment to exchange information with both ground command-and-control systems and other aircraft in an air warfare group.

The sophisticated control systems allow a pilot to concentrate on tactical tasks, while use of composite materials, the aerodynamic design of the body and measures taken to decrease the visibility of the aircraft engine provide for unprecedented low radio, optical and infrared visibility.

The PAK-FA development is still classified, so images of the stealthy fighter are expected to appear only after the first flight. Delivery to VVS (Russian Air Force) planned for 2015 as Russias basic front-line fighter.
