I'd say the Nosferatu is AC's most realistic/practical superplane design. It's got a sensible planform without the costly complexities of other strangereal designs. Most of it's unrealistic aspects lie in its weapons, I don't see things like the VLS Micro Missiles and Railguns ever being fitted to a real design, but with conventional weapons it would be perfectly reasonable.
Other planes could probably fly, but would be mostly impractical for the role.
