Armor: WW2 versus Modern

The UK could never afford such a thing, so you're left with the US, a federated Europe on a militaristic spending spree, Russia wasting it's oil and gas money, China deciding it needs toys or the Japanese going crazy.

I meant a joint project.

Why Patriot, ever heard of Standard missiles & ESSM?

ESSM, maybe, but the idea was to stop extreme missile spam, something that would be very common with lower tech nations, or even China.

Either you played too much Red Alert, or you mean Iron Fist? Could help, but you'd need a king-sized version to stop ASMs & guided bombs.

It could be Iron Fist. I think I may have forgotten the name, but it is attached to things like Jeeps to detonate rockets and projectiles before they hit the Jeep itself. A "king-sized" version could prevent, say, damage to the bridge or areas protected on the outside, but not on the inside.

A big ship would be a perfect place for those, yes.

a what?

The plasma wall is essentially America's forcefield prototype, capable of taking overpressure and heat. If this is on the inside, lucky torpedo/anti-ship hits will not do as much internal damage.

I think it would be much less useful than on a tank, no thin, fragile APFSDS and fewer HEAT warheads to disturb. OTOH many missiles or bombs with thick casings and much momentum.

This was more for torpedo attacks.

Will be fragile stuff...

Most likely. However its as cheap as aluminum foil. Easily replaceable, pocket change compared to the ship itself.

Oh yes it would! The USN pays more than a billion for a DDG and a CVN is 5 billion. A battleship sized ship would cost at least 3 billion or so.(probably more, since the cost for DDG-1000 has risen to more than that per ship, all three of them.:p)

I actually think this will cost around 15, maybe even 20 billion upon thinking about it. It depends more on the costs of the "FUTUUUUURRRRE" defenses.

Much depends on the tonnage of this hypothetical BB-21, a 40000 ton ship with conventional power will be much cheaper than a 100000 ton nuclear powered battleship. (and then there's the difference between cost per ship with or without development costs)

ESSM & Standard were designed for that very scenario! Massive missile attacks by Soviet bombers, cruisers & SSGNs.

Iron Fist it is then, an APS (active protection system, basically a baby-CIWS). There are a few others around as well. (Trophy, AMAP-ADS, Quick-Kill...)

Unfortunately modern torpedoes tend to explode under the ship, breaking it's back with the pressure wave of the explosion(any HEAT on a torpedo is aimed at the massive double-hulled Soviet/Russian subs, not ships). The best defence against those is a double hull with plenty of bulkheads in between and wet and dry spaces in between to dampen the force of the explosion. Similar to a WWII battleship's TDS (torpedo defence system) but covering the bottom as well as the sides. The problem is that it would eat much (very much) space, though on a conventional ship you could use part of it for fuel.

Another job for the Plasma Wall, perhaps?
