Damn, good work still. I just spent part of an afternoon going through this thread and getting caught up. Damn you for making the "assault gunboat" into a vehicle I actually think looks cool! I had a good, solid dislike for that vessel all worked up!
Seriously, you need a new thread. This one is getting "HUEG" as Shroom would say.
Also, for a note, I think the smaller, lighter ships --frigates on down-- are actually more sexy than the big hulking ubermightysooper-dooperbattleshipkampfwagenflotteshiffen type stuff. The ability to deploy, and creatively use, massed smaller maneuver forces is far superior for tactical and strategic flexibility. That Customs corvette is, actually, my favorite of your designs, followed by the fleet tender.
Plus there's the story angle. Those smaller ships, out on patrol in the backwater, are where eager young officers get their first real taste of command. They have the chance to actually know or at least recognise all their crewers, meet regularly with their department chiefs, and build bonds that will last years later when they've all moved on and gathered some rank. Young officers can indulge in a learning curve, maybe even a little more independence, and make bold decisions that can make or break careers-- and maybe bring them under the wing (or into the ire) of established, older officers.
Yessir, smaller ships and junior commands are where the real plot points are.
