Third PAK-FA prototype breaks cover

Russian-language spotter pages are reporting the first sighting of the third Sukhoi PAK-FA prototype at the Siberian flight test centre in Komsomolsk-on-Amur. As soon as pictures become available, we will post them.

The T-50-3 prototype is reportedly scheduled for first flight by the end of 2011. It follows the maiden of sorties of T-50-2 in February and T-50-1 in January 2010.

The third prototype is understood to carry the PAK-FA’s active electronically scanned array (AESA) radar. T-50-2 is an avionics and mission systems test aircraft, and T-50-1 is dedicated to flight sciences testing. 

Sukhoi has already completed more than 100 flights of the PAK-FA prototypes in less than 22 months of flight testing, including a chequered appearance at Moscow’s MAKS air show in August where T-50-2 had an engine blow-out on take-off.
