The Arsenal ship concept[1] paired with the idea of "crew optional" ships would be inline with this idea and also integrate with the data link capabilities intended for the F35 (where it potentially fires missiles it's not carrying at targets it identifies).

The thing which stands out about VLS systems is the salvo fire capability of them: VLS tubes can launch an entire ships ammo complement in as little as 60 seconds or so. Which is a massive advantage because it means if a ship is targeted it can still potentially service every single target in range before it's in any danger of actually being hit.

Yeah, and the reason the arsenal ship proposal been shot down time after time, by many nations, is because when you actually dig into it, it's a bad idea.

There's a minimum tonnage needed to mount a big enough radar, have a hanger for a helicopter, and plenty of room for VLS, RAM, etc.

But past that, it's better to distribute your assets across multiple vessels vs building one dramatically larger ship.

It's far better to have 4x Arleigh Burke style ships than one behemoth that's 4x the tonnage.

Heck, this was true even at the end of the battleship era. Just look at how useless the Yamato proved to be. And it's doubly true now in an era of very sophisticated anti ship missiles.

Also, conceiving of this in terms of single platforms is also just totally wrong. We assemble surface action groups with a mix of capabilities that match the situation. Some of our Burkes focus on anti aircraft warfare, other's anti submarine, so we send a mix. And when they're on station each hull can be in the location best suited to its task.

So really you have to think about the whole package, and the arsenal ship just doesn't offer anything desirable on that basis.

And then it has to go back to base to reload. Reloading at sea is marginally possible. The U.S. Navy has demonstrated it recently, in harbor. But it's not done routinely with live ammo yet. This is a known weak point.

The notion of a "crew optional" ship is a bit silly. It might have some utility for coastal defense: when it breaks down close to shore you can send a tugboat to tow it back. But I can't see how uncrewed surface vessels would be of much use to an expeditionary blue-water navy. Anything constantly exposed to salt water and vibration will break down. We're decades away from having robots that can do maintenance and repair.
