One would hope. The Newport Class LSTs were retired and sold off rapidly at the end of the cold war. The US Navy was transitioning to the “Forward From the Sea” doctrine which emphasized launching rapid, air mobile strikes supported by fast amphibious hovercraft from mobile Amphibious Ready Groups sitting over the horizon from possible threats, be those shore launched anti-shipping missiles or artillery. The LST had minimal well deck space and required physically sailing into the threat zone, and was thus discarded (along with the singular purpose LPHs).
By the time “our” Harrier was in service, the Navy was well into the process of switching to a more or less codified Amphibious Readiness Group that would consist of a LHA or LHD, an LSD, and an LPD. The San Antonio would be welcome, though I believe the trusty but rusty Austin class would be better representative of a wider era of conflicts. Along with that, by my reckoning an Anchorage, Whidbey Island, or Harper’s Ferry class LSD would also be necessary.
