So KSP 1.2 launched and I've been messing about with it. So here's the 200+ ton "KX-01" under the command of Jeb Kerman (because honestly: who else would fly this abomination).

Yeah: it's literally me applying the "trek rules of design" to KSP now that it's got proper large-scale dish arrays in.

None the less: has a bridge, crew deck, and two drive nacelles with a total of 8 atomic rockets for long-range use and the immediate back has more conventional vectoring engines for orbital adjustments close in to planets.
