Well, yes, but from my memory of B5 (and it's been a very long time since I've watched it), not much gets shown inside those earth capships. The bridge might be in that section. or, the spinning section is used for crew quarters or "comfort" areas, while the rest is gravity-free and the crew just have to deal with it.
Artificial gravity must exist in the B5 universe, as all the other races have it on their capships, and the white star has it...
anyway, aside from the abvious choices- starfury, A, X, and Y wings, etc, I really liked a lot of the designs from the early wing commander games- especially wing 2...
