Holy thread revival, Batman! Sorry for paleoposting, but this seemed like the best place to put up some Babylon 5 things.
Firstly, the SA-25A Muskrat heavy Starfury:
Frequently confused with the Badger-class 'fury (which would've had F-111 style side-by-side seating and never made it to the screen) the heavy Starfury was only seen in A Voice in the Wilderness in series 1.
SA-23A Nova Starfury:
Semi-canon in that it never appeared on screen but was part of the expanded universe B5 Wars tabletop game, the Nova was the predecessor to the SA-23E Aurora Starfury seen in the majority of Babylon 5. I borrowed the thrusters and thrust vectoring veins from DP and Paladin's Aurora but the rest is scratch-drawn based on B5 Wars designs. I'm knocking some Babylon 5 stuff together for some fan fiction I'm writing (yes, I know) and have some more stuff in the pipeline.
