Here's some new video of Russia's second Sukhoi PAK FA stealth fighter's first flight at the company's Siberian plant in early March. It's pretty good film of the jet which supposedly sacrifices stealthiness for better maneuverability against the U.S.' F-22 Raptor. Speaking of maneuverability, watch for the shot of the PAK FA's thrust vectoring engine nozzles in action at the 1:07 minute mark. You can also get some good views of what's probably the jet's infrared search and track pod mounted just in front of the cockpit canopy. This second PAK FA prototype is supposedly being used to test out some of the plane’s mission systems while the first plane , which flew for the first time last year, is being used to test out the actual airframe design.
This footage was apparently “officially leaked” by Sukhoi, according to a tipster.
