I feel this thread is quickly approaching the point of Agree to Disagree.
The battleship wasnt a specific ship it was a role. Heavy combatant ment to go into combat with other heavy combatants. For that it had specific traits. Heavy armor, heavy weapons, lots of redundancy. .
I really like this assesment. Very thought provoking
NO SHIP is going to be capable of operating alone agaisnt opposing navies or militaries. This was proven decisively with the sinking of the yamato. The future atleast in hot warzones lies with fleet action not individual super ships. .
Emphasis added. Another excellent point that I feel validates two separate thoughts. First, it is a statement to all those who theorize about some super ship operating alone with a million and twelve different roles and systems that the costs/capability breakdown is heavily skewed: too much cost, not enough capability. Secondly, I feel your statement also makes an unintended point that small, cheap patrol ships are still useful in navies today but get a lot of heat by naysayers because they feel those ships wouldn't survive in a shooting war. Those same naysayers ignore the fact that those small
cheap patrol ships (what LCS should've been, not what it is) wouldn't and shouldn't be operating in the war with the fleets but in all the theaters that still hold importance but that are away from the fighting so as to free up those heavier assets to operate in the waters nearest the enemy. But more on that in another thread.
I can see the return of the battleship as a peice in that over all puzzle. They wouldnt be hunting subs or launching marines on V-22's. They would be the heavy hitters of the fleets. Namely the Amphib fleets, and the fleets in the pacific. (a)Specilized for long range strikes with Tomahawks and short to medium ranged strikes with Naval guns. (b)And with a secondary skill in surface combat at either short to long range with harpoon missiles. (c)A pleathora of CIWS and other defensive measures would protect them wear others couldnt be. Surounded by frigates/ (not really my fav. choice but thats another story) LCS to provide escort vs subs or other threats outside its specialty. Backed up by the DDG's for anti missile/air work...
Emphasis added to help me reference your points. I'm having difficulty conceptualizing what the kind of ship you're proposing would look like or what niche it would fill not already being done by smaller, and cheaper platforms. I'll be using the USN for my comparisons.
(a) I feel between SSGNs, which are dedicated strike assets that can operate independently, and other surface assets, which are doing other things when theyre not firing cruise missiles like providing air or ballistic missile defense, that strike is very well covered and as cheaply as possible. The USN is already using this HiLo mix for strike with the above combination: dedicated solo assets and dispersed capability on multirole assets. Regarding the guns, unless a new heavy gun, upward of 8" or higher, is developed over and above the AGS then the need for a larger platform to carry it is unecessary.*
(b) I understand that you were listing ASuW as a secondary role of this ship but I feel it's worth mentioning that ASuW is fairly well covered already in most navies between smaller platforms using missiles like Harpoon and/or onboard helos firing the same
(c) between the escorting assets both large and small and a number of systems this ship embarks to defend itself we're talking alot of money spent in defending this platform. We already spend this much and more to defend and safely operate an aircraft carrier, but as I've said before in this thread, that cost is justified because of the huge capability we get out of an aircraft carrier that even the well designed heavy surface asset that you're proposing just cannot bring
*However, the efficacy and possible merit of a modern 10"-16" rifle aboard ship firing many different loads at supermax range albeit much more cheaply than any railgun type design is -very- interesting but the topic of another post
