well CC you can't call the Fw-190 "most perfect", firstly because as alder said, the Ta-152 for one was surely more perfect, but you could call the plane that was more perfect than the rest the most perfect, but that does not, by any means, make it close to perfect, just closer than everyone else.........
And technically you are correct. The last Fw-190D's were even renamed Ta-152's. It is just a how you look at it. I choose not to think it is the same plane.
no don't get me wrong i know that they're almost exactly the same plane, but to me the fact that it's been given a different designation means it can't be considdered the same plane.......
