Does the size of the Military Jump Drive matter for the size of the vessel being
towed or jumped three the Jump Point? Thanks
A few points:
1) Both. From the point of view of the jump, they're both just ships in the TG. (At least that's the way it should work
).
2) Note that the criterion for whether a ships is allowed through a commercial wormhole is not whether it's military or not, it's whether it's got military engines or not. Based upon this, I would expect (in the philisophical sense) you to be able to tow a military ship through a commercial wormhole using a commercial tug (the tow would just turn off its engines for the transit). In "reality", however, I suspect that Steve has coded it up simply to look for military drives in the TG, in other words I suspect that ships with military drives can only transit military wormholes. Note that you can dodge this by putting both a military and commercial jump ship at the WP, then breaking the tow for transit (i.e. break into two TG), transitting independently, the reestablishing the tow.
Note that Steve might not want to "fix" this, as it would create an exploit where military ships could use a commercial jump ship if commercial tugs were present - the technobble for this would be something like "the unstable the commercial wormhole is also destabilized by the high energy levels present in tractor beams".
3) It's probably a bad idea to put a jump drive on your tug - you'll be lugging all the (expensive) extra mass of the jump engine around when you're tugging, and extra engines are a very expensive way to pad up a jump ships's size when it's acting as a jump ship. A much better idea is to have a dedicated jump ship which has enough capacity to handle the tug and/or tow.
