>>6111442I'm not sure, honestly. It depends a bit internal space vs deck space - nuclear reactors are big and bulky on small surface combatants, and it's hard to say how much volume for VLS cells they would have available. I have so far been using a Ticonderoga-class cruiser's armaments as a model for a remodelled Long Beach and a Flight I Burke for the smaller Bainbridge to make things easier, so that would work out to 128 and 96 cells each. That's a little questionable with Long Beach given her proportionally narrower hull, and apparently she was already rather cramped to begin with (such as only having enough dining space for 1/3rd of the crew at a time), but it's a decent working model since I'm not a naval architect and don't want to get that far into the weeds.
A Ticonderoga-class cruiser's typical VLS loadout circa 2000 would be something like 82x SM-2MR, 32x TLAM, 8x VL-ASROC, and 8x Harpoons. In the real timeline the VLA wasn't procured in large numbers because the USSR went and died and took most of both its submarine fleet and the USN's budget with it. We can imagine there might have been more of them made in this timeline.
As to what loadouts Long Beach and Bainbridge came back to life with, I suppose that depends a lot on what mission they were expecting to perform. Did they come back as carrier escorts, or as lone wolves? Would they be more focused on anti-ship, anti-air, or land attack? I think the average numbers quoted above are fairly reasonable to use since they cover all the different missions of a modern US surface combatant reasonably well.
