Instead of all around rolled homogeneous armour.
It had era and nera modules all around. This makes easier to replace the everything.

Make the entire ship as autonomous as it can be. So it would need a very small crew.

Modern sodium batteries to store energy, as they don't explode like lithium batteries.
Solar panels on top of the deck, to recharge the batteries. A backup diesel generator when the weather is bad.

No explosive shells, just some big fucking rail guns. As most of the battleships were sink when a bomb reached the ammo storage, there would be no risk here for a big ass explosion.

Some laser weapons too for AA defense.

I don't see any way this could be sink. Almost nothing can go kaboom inside. This would be unsinkable.

Do you think torpedoes just stopped being developed?

Risperidone is a hell of a drug.

>most of the battleships were sink when a bomb reached the ammo storage
All the battleships that were sunk, were sunk when a bomb or a torpedo let the water in
just like with most warships sunk in combat (there are a few exceptions)

>What weapon could sink a modern battleship?
A torpedo or 2000lb bomb exploding under its keel to break its back so it collapses under its own weight
or exploded just under its stern, which would destroy its propellers and rudders

>sodium batteries don't explode
The kind that you'd use in a phone would explode just fine. They belong to the same column in periodic table with sodium being even more reactive than lithium.
Go find videos on youtube and see what happens if you throw sodium in water, and see the same with lithium, compare which is more violent.

Just shoot with the rail gun.

All of them.

You are retarded. The way a tank defends against a shaped charge or long rod penetrator is basically irrelevant to how a ship defends against a half-ton (at the small end) anti-ship missile.

A lot of everything else is things that warships already have. Or you're just wrong about. A railgun might not cook off, but electrical fires are possible.

Please don't feed the retard, he'll use your post to prompt new slop for his next thread.
