Eh, becuase I feel like it.
My thoughts on the 'Yamato vs. Iowa' thing. It might be useful, might not.
"The Iowa-class Battleship had an armanant of nine 16in guns, divided into 3 batteries. The Iowa's 16/50Cal shells weighed 2,700 pounds, and could fire accurately for as far as thirty miles, if memeory serves me. Their back-up weapons were 5in/38Cal shells, as well as a large number of 40 and 20 millimetre weapon batteries. The Iowa's armour was definately not as thick as the Yamato's, however, it significantly could outrun the Yamato: The Iowa classes top-speed was 33 knots, while Yamato's was 24-27 knots. The famed German battleship Bismarck, for example, was capable of going up to 29 knots in optimal conditions.
There were four Iowas built: Iowa, BB-61, New Jersy, BB-62, Missouri, BB-63, and Wisconsin, BB-64. There were originally supposed to be six of them, the Illinios, and the Kentuky, which was fairly close to being completed.
On the other hand, there was two Yamato-class Battleships, the Yamato and the Musahshi, both of which suffered inglorious deaths: Mushashi was sunk in the battle of Letye Gulf, after taking a massive amount of damage.(Mushashi took 17 torpedos and 20 15,000 pound bombs. For comparison, the strongest bomb that the US had, short of the Nuke, was a 5,000 pound bunker buster IIRC. That is an incredible amount of firepower no matter how you slice it.)
Yamato wound up being sunk in a suicide mission against the US navy at Okinowa. Now, both never fought each other, but What If?
Yamato-classes armanant was nine 18.1 in. gun batteries, which wa sdivided into the same 3 gun battry arrangement as the Iowa-class. Her secondary armanant was 6.1 gun batteries, and had a smattering of 25 and 13mm gun batteries, which like the Iowa's 40 and 20mm were used for anti-aircraft duty.
Yamato was superior in terms of gunfire, but the US 16/50Cal guns were better at penatration. Yamato's real downside against the Iowa-class, aside from the fact that the American Battleship is much faster, is the fact that the Yamato-class' fire-control were decidely medicre. The Iowa used a Radar-control fireing system which by WWII standards were extremely accurate. Yamato's fire-control wasn't nearly as good.
Bottom line: Iowa had at least a 50% chance against The Yamato class, at the least."
