Iowa Class Battleship dimensions

The forward gun turret of uss Missouri

The main battery of 16-inch (406 mm) guns could hit targets nearly 24 miles (39 km) away with a variety of artillery shells, from standard armor piercing rounds to tactical nuclear charges called "Katies" Each turret required a crew of 77—94 men to operate

The design power output was 212,000 shaft horsepower (shp), with a 20% overload (up to 254,000 shp). During the New Jersey’s sea trials in December 1943 the engine room generated 221,000 shp, clocking 31.9 kts with a displacement of 56,928 tons. The Iowas were the fastest battleships ever built, by a wide margin. Their design speed was about 33.5 kts (38 mph), but a lightly loaded hull (51,000 tons) would have been capable of achieving 35.4 kts (40.25 mph).
Some Interesting Facts
Designing the Missouri took 175 tons of blueprint paper. The ship was built in three years and required over 3 million man-days to complete the job.For comparison’s sake, the Missouri is 279 feet longer and 11 feet wider than the USS Arizona. The Mighty Mo is also 5 feet longer and 18 feet wider than the RMS Titanic.Just how big is the Missouri? If you could stand the ship on end, it would be 332 feet taller than the Washington Monument.The nine 16-inch guns are the Mighty Mo’s trademark feature. Each gun barrel is to approximately 67 feet long, weighs an incredible 116 tons, and can fire a 2,700-pound shell 23 miles in 50 seconds — with pinpoint accuracy

Displacement: 45,000 tons (standard);
52,000 tons (mean war service);
58,000 tons (full load)
