This is a revolutionary next-generation forward-firing anti-submarine rocket weapon developed to counter the increasing threat of submarines.
The base version was plagued with problems during actual use, but this is a what-if version where improvements succeeded in reducing the rate of misfires.
The main concept behind this weapon was succeeded by the famed ASROC ASW weapons system.
