Well, since the topic wasn't WWII specific, I'd have to say I've got a few.
WWII: Ta-152C
Korea: F-86F (was there ever a doubt?)
AU-1 (there is just something about all that power!)
Vietnam: F-4C (gotta love the short nose Phantoms)
Modern: F-15E (I know a lot of you are gonna say "why not the C?" Just doesn't fully do it for me. Gotta have that ground support element in there too!)
Ok, so I'm a bit Ameriphilic, but still, they are great airplanes!
