Yes, you get your gold star, and an extra one for not confusing Friedrich Krupp with Fritz Krupp, nor Alfred with Alfried. You lose the second one for confusing Fried. Krupp of Essen with the Gusstahlfabrik, though. That was the main Essen steel plant, and only part of the empire.
Regarding the one-engine debate... that's been going on for a while now, and while it isn't conventional for modern fighters to have just one engine, it seems to have worked out
really well over the course of its service life for the F-16, which was one of the best all-around fighters of its generation. In other words, it's been proven to be possible.
No, I'm not confusing the Eurofighter with the Gripen, though that would be understandable. I'm talking about the Eurofighter Typhoon, developed jointly by a variety of NATO member-states to replace the Tornado and, in Britain, the Jaguar, with the possibility of export sales. The Eurofighter looks to have quite a bit more in common with the E/F generation of F-18s than with the F-22, but that's hardly surprising - in a lot of ways, the US Navy got left out in the cold in the stealth-aircraft race until the JSF project began to move forward.
I'm still going to have to point out that the Su-37 has a lot more in common with the F/A-18E than with the F-22 if you were looking to do a fair comparison. The Soviet-leftover fighters that you're looking for are the Su-41 (I believe that's its official bureau number now; used to be just the S-37) and the MiG Art. 1.42. At least the Article 1.42 was never developed into a production fighter, and there are some doubts about whether it even flew.
