well, I'm more interested in pirates detonating a nuke near a ship (how near I'm not sure yet), the idea is to damage it enough so that:
internal grav goes down/off
comms are knocked out
GT has some rules concerning hardening, but I'm wondering how they apply to gravity plating, more than anything.
it's likely that a ship would have uniform hardening, depending on the GM and if the players own it -- their paranoia level.
a while back I'd posted a question about gravity affecting missile weapons, well now go the other way and if you can knock out a defensive system, well, you get the picture...
anyway, I'll probably just use the ship's TL and figure on uniform hardening based off of that, in lieu of actual specifics.
