Dan as usual
And Diablo:
"The Iowa's were truly a marvel of warship engineering. The punch of the Yamato's with greater accuracy, the seconday armament of 4 Fletcher class destroyers (or just over 3 Gearing class), the best damage control and fire control available, armor almost equaling that of the Yamato's, the top speed of many destroyers, the ability to turn with destroyers during maneuvers, and still able to fit (barely) through the Panama Canal. Without doubt the greatest BB class ever built. "
You're a Navy guy, - cool

Those ships were indeed the ultimate BB's. If AH would introduce the BB, I'd put my money on those. They're U.S. they were some by numbers and they were top-notch.
That said, I'd still like to see Bismarck, KGV, and Yamato

Bismarck for fame. Famous, good looking, and took a lot to sink.
KGV for service. Those were working a lot. Heavily armoured for surface engagements, and with a slightly smaller calibre the ROF is high.
Yamato for the bulk. Sheer bulk and big gunz!!!!
