New Haven Class Heavy Cruiser

The idea of 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
