Super Yamato A-150 class BB

[TheDreadnought]

Here you go. I feel its a little unfair to give the Montana only "as-designed" AA, while giving the A-150 late-war AA. . .

. . .but who are we kidding. For these monsters, the only guns that are going to see any action on the tabletop are the main batteries.

The only issue I see is that the guns/turret for the 20.1" guns should be 2 not 3...

Wow, that ship looks pretty mean. Tomorrow I'm going to try a one on one against Montana before doing a monster battle on my basement floor with 1 super Yamato, 1 Yamato, 1 Nagato, 1 Nachi, and 2 Furutakas vs. 1 Montana, 2 South Dakotas, 2 Clevelands, 1 Baltimore, and 1 Northampton. It's just around 4000 points per side so I should be at it for a while. I think all my furniture will be islands just to make things more amusing.

You can have a late war/post refit version with the same rating as the Iowas. I'm not 100% sure if the longer caliber 5" guns had radar proximity fuse AA rounds, but I think it's safe to assume they would have put 40mm and 20mm AA's on all deck spaces where it would be possible. She would have still put up one impressive curtain of steel for the enemy aircraft to fly through.

[TheDreadnought]

Well the design called for "8 or 9' 20" guns in triple or quadruple turrets." Elsewhere in the article it mentions 6 guns. I could go either way. Thoughts?

[BattleshipOverkill]

Oooops! That was my fault on the gun count.
Sent ya the corrected card with 2 guns per turret, Harry.

Dreadnought

as it's a what if ship I'd leave the guns at nine and just let people alter it to six if they think that was more likely. It's much the same as the Alsace class which had three possible designs of 9 x 380mm main guns, 9 x 406mm main guns or 12 x 380mm main guns. The only thing I would do is give a points value for the six gun variant for people who use the points system.

I'd design all three since it is a what-if ship. If you want to spend the points for nine guns, well go ahead.

[mpc2163]

I'm sticking with the six gun variant because that's what my model looks like if you squint at it, cock your head to one side, and dance like a chicken. So far it's been running around the table doing terrible damage to some old US battleships. It also did some terrible damage to USS Indiana, so it is a pretty potent ship. Montana came close to one-shotting Mutsu from halfway across the table. Those twelve dice are pretty scary.

[BattleshipOverkill]

Why don't we just go all out and I'll work on the data card for this bad boy:


To counter it the US will get this:


and this:


How many dice do you think one would get to roll for the nuke? ;D

The problem with having 3 guns in the turret is weight and the mass of the equipment necessary to load the heavier shells. It would most likely have been possible but not practical.

[shigure]

Wow!!! An impressive design (Mogami on steroids). However, I wonder what purpose the cat statues (on each side of 'B' turret) played in the design??? As the ship has no smokestack, that must be a [glow=red,2,300]nuclear reactor [/glow]aft of the super-structure.

I completely agree with BattleshipOverkill, that a triple 20.1" turret would have weighed much more than the twin 20.1" turret. In Friedman's U.S. Battleships: An Illustrated Design History the USN considered a quad 16/50 turret for some of the preliminary Montana designs. The quad turret weighed in at 2,064 tons compared with 1,622 tons for the triple. This meant increased electrical generation power to handle the weight and more horsepower to to achieve the same speed. In addition, as BattleshipOverkill mentioned the supporting structures would need to be heavier. If rounds per gun requirements stayed the same the magazines would need to be bigger. So I don't think the standard Yamato hull is capable of supporting a triple 20.1" turret. If you want that then the speed is going to be reduced or you're going to have to give up some armor.

If we want a triple 20.1" x 3 turret armed Yamato we will have to upscale the design to keep up with the IJN design principles.

I think the cat statues were designed to keep rats off when it was tied up at the pier. ;D

That makes sense to me.

Must have been some big rats, as when I blew up the picture there is a cat statue next to the reactor and 'Y' turret. It also looks like the close-in AA is Phalanx type units with the little radomes on top.

This guy had quite the imagination as he also developed ships for other navies as well.

[fluorophil]

I agree with Shigure, the Combined Fleet website is pretty impressive - and I also like his imagination with the other ships...and with a little more hard work, maybe we can develop some ships like that...

[TheDreadnought]

Here's the 6 gun version card.

Wow, that does make a difference in points. I generally don't follow the point structure all that much when designing scenarios, but I can see why it was just holding its own against a South Dakota in the game I just finished.

[shigure]

I know I'm being a pest here, but could you change the 21.1" guns to 20.1" guns whenever you get time.

[BattleshipOverkill]

Not sure how that happened. All I changed on the last card was the gun count from 3 to 2 and the old card still had them listed as 20.1" guns. Very weird.

[shigure]

That was what I thought I saw on the original. Well at least it was consistent...
