There’s no doubt about that, but there’s nothing else readily available, nor anything near-term in the pipeline.
It doesn’t work like that. You just don’t dial up HQ and ask for these parts, to be drop-shipped to the nearest port. If you need the part, and it’s not in aboard, you either get it from another vessel, or you do without until you can get to someone who does have the part. Let me give you an example: Returning from the Persian Gulf in late 1991, the USS Fanning lost her brine-overboard pump for her distillation plant. Without that pump, she couldn’t make fresh watter, and without fresh water, she was DIW. Dead-in-the-water. I got the pump’s impeller and volute in my shop, because there was no other parts like it in the battlegroup (low-failure parts, and on an uncommon design). The impeller was so damaged that you could literally read a newspaper through it, and the volute needed extensive cold-patching and shimming. When I was done, they had an impeller that lasted until the USS Cimmarron (supply and replenishment vessel) could reach the battlegroup. Had the battlegroup not been escorting us (a Submarine Tender) home, the Fanning would have spent three or more days bobbing powerless in the middle of the ocean.
As for hospital ships, we only have two, and until Reagan went for his “600 ship navy”, we had none. Even today, the hospital ships only leave port in the event of a major shooting war, major disaster, or to prove that they still float. In-between these events, it’s up to the LHAs, LPHs, and CVs to handle the hospital ship duties. The BBs would be a welcome addition to that service.
Planning your miltary to peace is a good way to get caught flatfooted and without the capacity you need when you need it. I’ll grant you that the US has a long tradition of doing just that, but that doesn’t make it any smarter.
This is the line the Airforce keeps taking, but it’s been disproven time and again. In every circumstance where airpower has been applied, significant numbers of the enemy remain unkilled, ready, and willing to fight back. The Marines know this, and as masters of their trade, if they think they need heavy artillery, I’m going to take their ward for it. Even the pasting given the Iraqi failed to render them combat incapable. Sure, many of their units just folded, but some of their units put up one hell of a fight, and had there not been combined forces ready to take them, we’d have taken heavy casualties. Combined arms is a deadly combination, but it means combined. Airpower, artillery, infantry, and armor all working together.
Politics, inter- and intra-service rivalries. Read up on the story of the M-2 Bradley development if you want a first-rate and well-documented story of offical military mendacity. If you don’t want to read, watch the “Pentagon Wars”, produced by HBO. My father personally knows the Airforce officer that kept rocking the boat, and considers him a hero.
