Is it a small frigate style ship?
Gun class would be nice to be high, but a upper standard turret would suit what I will put it to use for.
The crew number needed?
It's size, so how easy it is to move around on board?
Dose it have a form of docking or a hanger?
Those are just a few questions about what would be most ideal to have. It doesn't have to tick all those boxes but close will do.
Just to say, this ship will be used for mostly a training course and or running small missions for outer rim system sweeps.
