Russia’s PAK FA fighter prototype, billed as a strong competitor to the US F-22 and F-35 fifth-generation fighters, made its first flight Friday. The Sukhoi-built fighter flew for 47 minutes, raising and lowering its landing gear. According to video of the flight, the PAK FA has design similarities to the Lockheed Martin F-22 Raptor. Sukhoi has said the aircraft will undergo two years of test flights before entering full production. The company said the project has cost $8-10 billion, and that individual examples of the PAK FA, which will likely be called T-50 in operational service, will cost about $100 million each. The Russian Air Force expects to begin fielding it in the 2015-2017 timeframe. The aircraft is a joint venture of Sukhoi and Hindustan Aeronautics of India, which also plans to field the new fighter in a two-seat version. USAF officials have expressed concern that the PAK FA would rival the F-22 but be produced in F-35 numbers.

Contracts for F-35 airframes in Lot 18 and 19 should be signed in the spring, but an engine deal is still not in hand and could take months longer. The delays don't seem to be driven by anticipation of how the new Trump administration will influence the program.
