The Iowas could be slender, athletic, and tall, given they maxed out to barely fit in the Panama Canal. They also had ludicrous amounts of horsepower. Heck, they only needed four boilers to outrun most of the Japanese, and at flank speed easily the fastest battleships around. They also had one of the greatest AA loadouts ever for a Battleship, and her guns fired super-heavy rounds that are right up there in power, just below Yamato's 46 cm guns.
