That's a beautiful looking aircraft, them Russian are just amazing aircraft designers.
Beautiful? YES, Stealthy? not really, and two shallow weapons bays....
So yes, very pretty, and flies very well, earlier structural issues have been rectified on each of -1 prototypes, so yes they are back in business,,, now their partners the Indians?? I think they are still very skeptical and feeling used and abused??
3D OVT guarantees that's it is highly maneuverable, and if it finally get the "dream" engines, it will supercruise and be very fast, so while it may be faster?? and it may well even be more maneuverable than the Raptor, and definitely more so than the F-35, both the Raptor and F-35 will likely be vastly superior in a one on one mano-a-mano , they are most definitely more stealthy, and have more sensor fusion.
