What about missile pods ? Fighter sized pods, without shields, which fire apocalypse missiles (8 at the same time for example, but only for 3 reload cycles). They would be deployed like mines, by mine layers. I took this ideas from Honor Harrington books
It would be a bit like GTVA beam pods in retail, used to blocade a node aginst NTF, but in a more terran style.
It could look good, deployed in big geometric forms, lights blinking all at the same time.
