Major Work Ahead on Russian Stealth Fighter

Russia has begun flying a stealthy fifth-generation fighter to rival the U.S. F-22, but Western analysts question whether Sukhoi can develop and deliver the aircraft by 2015 as promised.

Sukhoi's T-50, which made its 47-min. first flight on Jan. 29 from the KnAAPO facility in Komsomolsk-on-Amur, is the prototype of the PAK FA "future front-line aircraft," the first new-generation fighter for the Russian air force since the Su-27 Flanker entered service in 1984. India plans to co-fund development and co-produce the new aircraft.

The aircraft is clearly shaped for stealth, with the chined forward fuselage, planform edge alignment, internal weapons bays and small vertical tails. The T-50 shows resemblances to the F-22 Raptor, but also reflects its Su-27 heritage in the wide "centroplane" that blends the fuselage and wing.
