Sukhoy announced that its third PAK FA prototype conducted its first test flight today. Operating from KnAAPO’s factory runway, the aircraft flew for more than an hour.
To run back a few milestones, the first PAK FA flew on January 29, 2010. A second prototype joined it in March of this year. PAK FA’s first public flight was August 17 at MAKS-2011. And Sukhoy says the PAK FA has completed more than 100 test flights to date. The hundredth flight apparently occurred early this month or in late October.
On November 11, ARMS-TASS reported that the third prototype will test the onboard phased array radar (AFAR) system designed by the Tikhomirov NII of Instrument-building (NIIP). Nezavisimoye voyennoye obozreniye published the same news, citing a Sukhoy spokesman.
