Full of 'em lately, aren't I?  Not entirely sure these are new (somebody must have had this idea already), but I'd like some feedback on costs:

Weapon trait, Volatile:  Any time a volatile weapon is destroyed, immediately roll one die on the ship's damage chart, which *can* trigger further rolls if more Volatile weapons are hit.  SU multiplier x0.5, maybe?

Equipment, Volatile Drive System:  Any time a ship with VDS takes an Engine hit (ie loses a movement point), roll one die on the ship's damage chart, which *can* trigger further roll if more Engine hits are caused.  SU's of Engines x0.5, perhaps??

Volatile systems may not be repaired by any means during the course of a scenario, although other damage caused by their explosions may be.

Good for modelling explosive ordnance of all kinds (weapons) or engines that run on antimatter/black holes/plain old rocket fuel (drives).  Also good for building those "firecracker" ships you see in a lot of anime...you know, the Nameless Bad Guy designs that show up in groups of at least a thousand and appear to have packed their cargo holds full of nitroglycerin before the battle.
