Interesting concept art of Russian’s new Sukhoi PAK-FA fighter jet, informally dubbed the “Raptor Killer” by Russian aficionados. Scheduled for its maiden flight later this year, the PAK-FA purportedly boasts many of the F-22’s bells and whistles: stealth, supercruise, advanced phased array radar, and the latest in air-to-air and air-to-ground missiles. Sukhoi is keeping the PAK’s design pretty close to their chest, so no telling if this is a true to life rendition of the bird or just the fantasy of some talented Russian artist.
