Clearly I have been out of the Navy for awhile, but this seems very confusing. I get the transition from HSL to HSM...pretty much the same missions just upgraded capabilities. But now there is HSM expeditionary (traditional HSL deployments) and HSM on CV. So what is HSC? It's not HS and HC, because they do no ASW. They claim to have an overland capability, but apparently training and equipment fielding make that a tenuous claim. ASUW? But they lack the sensors to acquire targets. VERTREP and logistics? OK...but why not just HC? HSC is deploying on USNS ships too, correct?
What exactly is HSC?
