The Iowas run on heavy fuel oil. They carry 7,000 tons of this oil, (about 2 million gallons) and are run by 2700 officers and men.
From cold start up on all eight boilers to 10 knots takes over four hours. When full power is required, you can observe the exhaust plume for miles.
No question about the armor, but one missle into rudder and they'd be 2700 sitting ducks.

They do not run with a 2700 man crew in their current configuration. They currently run on a crew of 1100 -1200 hundred. The reason is because they no longer carry 160 anti-aircraft guns which were individual crew served weapons.

You are also incorrect about their fuel system. During the 80's refit their boilers were upgraded to burn marine diesel as all of our gas turbine powered ships do. Their enormous fuel capacity allowed them to act as tankers to refuel their escorts. You are using their as built specfications which are invalid points in making your arguements.

Propulsion is one of the upgrades being talked about. With modern propulsion systems, these points are irrelevant.
