Yeah. Followon Operational Tests on Alaska (732B). Only Mk 48s we shot were exercise loads in TREs in Hawaii. Never had the "priveledge" of dealing with SUBROCS.
You really don't want the "pleasure" of playing with SUBROC's.
Granted, it's sovbering to see the actual nuke warhead, but there's no real valid reason to use one....
Unless you're a Taiwanese sub looking at several hundred landing craft headed into your island!
