Vition2, about my PM...
Would it work?
Yes or No.
Thanks all,
TT
Based on a couple assumptions: No.
First, the dropship and warship would have to disconnect from each other to engage in combat maneuvers. Maneuvering in combat is not possible when a dropship is attached. I forgot about this until just a few minutes ago, otherwise you'd have already seen a PM about it.
Second, using a dropship as "supply" ship in order to use all the mass available to the warship is entirely possible, and something a medium-sized fleet should think of to reduce costs.
The major assumption I'm making in your proposal is that you are intended to use the dropship to land on a planet to resupply itself, then attach to the dropship to become a virtual mobile "beans and ammo" depot. Since I'm going to back off on gaming the system a bit, this means you would need a dropper with at least a 3/5 thrust profile.
I hope that answers your question adequately, if not, I'm happy to field more questions. :D
