I'd say, "call that a Terran/Vasudan destroyer, it doesn't feel totally Vasudan...."
If you want to make something that looks Vasudan, make something that looks like a cross between all 3 capship classes, a bit of Hatshepsut, Aten, and Sobek, give it a graceful, organic-like structure, with launch tubes like the Hatshepsut (make

of them, maybe 3 on each side) and possible give it 2 arrow head fronts, one on top of each other connected to the body by 2 necks. Just use the existing Vasudan Models (from FS1, FS2 and Inferno...cause Inferno is basically FS3) and form you're on ship around them!
