Death Battle:USS Iowa vs IJN Yamato

The Iowa wasn't as large as the Yamato, both in terms of gun size and overall size, but it was significantly faster, more accurate, and its smaller shells had a significantly higher muzzle velocity, enabling it to as much damage, if not more. Also, because its shells were smaller, the Iowa could carry more ammunition, and fire it faster. Not that it matters in the end anyway, because all four Iowa-class ships are currently busy being floating museums, while the Yamato is busy being a tetanus-infested coral reef.
