Weapons Concept Question

Hello, to all

I was chatting with a good friend yesterday and he mentioned that he'd just
read an Honor Harrington novel and wondered whether FT had towed missile pods?

I had no good answer for him, but a number of really nasty concepts arise from
the question. Has anyone worked up these? if so could they let me know what's
up Mass, cost, options? If not then, does anyone have any suggestions?

Thanks and sorry for the long winded question
