MOSCOW, Jan. 28 (Xinhua) -- The Sukhoi T-50, Russia's fifth-generation fighter jet, was to make its maiden flight Friday after a one-day postponement, the manufacturer said Thursday.
No reason was given for the postponement.
The Sukhoi T-50 was designed to rival the U.S.-made F-22 Raptor and F-35 Lightning II fighter jets.
The new fighter will be armed with next-generation air-to-air, air-to-surface and air-to-ship missiles, apart from two 30-mm cannons, according to the RIA Novosti news agency.
The T-50's, whose combat capability has been greatly enhanced, will enter service in 2015 and replace the MiG-29 Fulcrum and Su-27 Flanker fighter jets.
