In C# Aurora, can a Space Station (i.e. a Ship with a Structural Shell) use a Jump Drive? The C# Changes say "No engines", but don't specify whether or not a Jump Drive counts. Jump Drives don't confer thrust after all, and a Space Station w/ a Jump Drive still needs a tow PLUS it needs enough mass to serve it's intended role, so it (probably) wouldn't be too broken. After all, a 1,000,000 ton rated Commercial Drive strapped onto a metric F Ton of crew quarters would still need a tug for it's massive 1,000,000 Ton self.
EDIT: Jump Drive Tonnage is no longer dependent on Ship Tonnage, so the 1,000,000 Ton Jump Station in question would not need to be 1,000,000 Tons itself. I still think Jump Drives on Space Stations would be cool, since a CIWS is currently the only weapon that counts as a Commercial System, making them vulnerable if unsupported.
