The Sukhoi T-50, first new military aircraft since the collpase of the Soviet Union flies. Similarities with another production aircraft are, errrrrrrr, striking
It's almost like they started with a YF-23, but that lost, so rather than waste their work, they added a bit of F-22, and were just about done when the F-35 came along...
Probably not Leif - because under those fancy body panels it will be a cleverly constructed collection of tried and tested soviet agricultural machinery parts. Bet it leaks oil everywhere though
BTW, it's only Russian pistons that leak oil everywhere and that's because they copied us Americans in that regard.
If a Russian jet leaks anything, it doesn't fly. Meanwhile, we Americans didn't learn and (for example) actually have prescribed drip rates for the F/A-18's Engine Oil and Hydraulic system.
