We should impose another economic sanction on Putin; sue them for stealth patent infringement Apparently some engine bugs to work out : http://www.militaryfactory.com/aircraft/detail-page-2.asp?aircraft_id=782

One good example is stealth. The T-50’s design places far less emphasis on all-aspect low observables. Instead, it focuses on frontal aspect stealth—thus it has a so-called “Pac-Man” signature where as the F-22’s signature looks more like a spider if one were to look at it from a God’s eye view. Stealth is where the F-22 holds a huge advantage over the Russian jet.
In terms of sheer kinematics, the T-50 and the F-22 are probably comparable—especially once the PAK-FA receives new engines. The Russian jet’s current Izdeliye 117 engines are decent, but ultimately the plane will need to reequipped with the developmental Izdeliye 30 motors to fully exploit the capabilities of its airframe.
