New Haven Class Heavy Cruiser by Tzoli New Haven Class Heavy Cruiser by Tzoli
The idea of :iconsiveir: an improved Baltimore class Heavy Cruiser featuring 4x3 8inch (203mm) Anti Shipping Guns 8x2 5inch (127mm) and 10x4 40mm AA Guns. (Baltimore had 3x3 8inch, 6x2 5inch and 12x4 40mm Guns)

As you can see I've added an extra 8inch Triple Turret, Replaced a pair of Quad 40mm Bofors AA Guns with a Pair of 127mm AA Guns and used the Single Funnel of the Oregon City and Des Moines Classes

I call her New Haven class I use the Baltimore as a basis but introduce some changes seen on the real follow up classes like the Oregon City and Des Moines classes

Nice work, and nice idea. Though I would have used the Des Moines class as a bases. With 12 rapid fire 8" guns, it would have outclassed some battleships.

Had some been really build, I wonder the kind of damage they could do by mixcing high firing rates with the eight inch weight of the shell. As for bombing coastal emplacements, would have been devastating. It could have been quite used at Vietnam on the 60´s, for instance. or have been rebuilt as massive missile cruisers, maybe not need delete any gun, placing a couple of twin tartar/terrier/talos launchers on the aft superstructure.

Tartar and terrier launchers are needed quite the space so the aft turrets probably be deleted.
Many cruisers were proposed for such conversion:
Wichita, Baltimore, Cleveland, Des Mines, Alaska, and so on!

Hehe, I imagine how could have been lookin if they had kept the Alaskas as missile battlecruisers!

Half conversion would be similar like this:

Official proposal is like an aircraft carrier, but the ship don't have a flight deck.... Those are silos!!!!

Okay, what do you think about these US cruisers:

Hull, Engine and Armour are the same as my New Haven Class:
Des Moines Hull, 6inch belt 3inch deck, 120K shp
But with these Weapon layouts:

Weapons are:
8inch: Rapid Fire Mark 16
6inch: DP / Rapid Fire Mark 16
5inch: Mark 16

A: 2x3,2x2 8inch, 10x2 5inch AA Guns (2 superfiring centreline, 4 on each side)
B/1: 4x2 8inch, 2x2 6inch, 4x2 5inch AA guns
B/2: 4x2 8inch, 2x2 6inch, 6x2 5inch AA guns
C/1: 2x3 8inch, 2x3 6inch, 6x2 5inch AA guns (2 superfiring centreline, 2 on each side)
C/2: 2x3 8inch, 2x3 6inch, 8x2 5inch AA guns (2 superfiring centreline, 3 on each side)
C/3: 2x3 8inch, 2x3 6inch, 10x2 5inch AA guns (2 superfiring centreline, 4 on each side)
D/1: 2x4 8inch, 2x3 6inch, 6x2 5inch AA guns (2 superfiring centreline, 2 on each side)
