For lighter ships maybe, if there is some general agreement about not using nukes against ACS that don’t pack NDs, or smaller ships looking for an outside chance at a big one.Sounds like a sensible progression (from a weapons-development perspective, insane from a humane perspective).
If they’re immune to sand would they be a weapon of choice after spinal mounts?
Otherwise, just use nukes on ACS- a little less likely to get through but a whole lot more sure destruction.
Hmm, should have to hit tied to same battery value as laser/energy equivalents, and an SS4 to hit as though you were attempting impact.
