Yeah i need to sort out a fit that lets me safely knock out the generators and scoop the mechanisms.
I equipped two AX missile launchers. You can hit a generator from a decent way back, and a few seconds later the generator will explode violently (which usually causes caustic damage to start up on your ship, but one decontamination limpet takes care of that).
As long as you keep on top of caustic damage and don't go too deep into the cloud you could do this for hours hypothetically (or at least till you went through 128 missiles).
