Ship building.... the hard way...

The idea of building a Waldburg from scratch is neat. You'd even have
the FT design system to give you an idea of how much space to write off
for drives, weapons, controls, etc.

Assuming it is about 40mm long (Tony's number?), that makes it about 80m
long in RL. Inside probably about 75m. That's about 37.5" in FMA
Skirmish scale. A three foot long ship, with about 5-7.6" wide (10-15m).
It'd probably have about 4-5 decks at its largest part.

You could build the decks so they stack, but if you really wanted to
play it, you'd get two 8' x 4' tables, and you'd lay out all the decks
side by side, that would make moving and conceiving of things reasonably
easy.

A complex, but very cool, idea.

Fight your boarding actions in FT the "hard way".

But Jon would have to come up with some (and he should!) Naval Boarding
Parties. Yes, marines would have PA probably, or combat armour, but it
would have to be zero G equipped (mag boots, thrusters, etc) and your
normal boarding parties should at least have a vacc suit. If Jon put out
a standard Vacc-Suited figure or three, he could just change say helmets
and firearms and he'd be able to (with the same body stems) do Naval
Boarding Party figures for all the nationalities!

They should probably use laser carbines, laser rifles, gyrojets, etc.
Plasma guns, AARs, SAWs, Shotguns, SMGs probably all make cruddy weapons
for fighting once a ship turns off artificial gravity (something which
the Marines would like - its like a plus for them - they know how to
fight in it, but their assailants (if normal troops or terrorists) might
not). And once you evacuate an area, that means that any suit hits that
are not self sealing (most military suits would be, but civilian ones
might only be on more pricey models) would be probably lethal or at
least preoccupying. Plus in pressurized chambers you have to watch for
blow-through on walls - explosive decompression is nasty.
