The Montana Class Battleship was never built, hower it varied with the Yamato on paper by being of about the same tonnage, almost 100 feet longer with more (12) vs (9) but smaller 16 in vs 18 inch guns. The Yamato had a larger crew, heavier secondary batteries and heavier Armor and a seven floatplane air division. Longer, yes, and a lovely ship.
The Yamato had bigger guns, but Montana had fire control radar making her much more accurate as well as 3 more guns.
Edge Montana by a long way.
USS Arizona (BB-39) was a Pennsylvania-class battleship of the United States Navy.http://en.wikipedia.org/wiki/USS_Arizona_%28BB-39%29
The largest battleship was HMS Hood, which was destroyed by Bismarck with a single shell hitting the magazine. It was so devastating, that the ship was forced upside down on the sea bed - the only wreck ever to have done so. There may have been bigger aircraft carriers, but they are not strictly battleships...
Gun wise, was an Iowa class battleship. Most powerful (regardless of guns) was an aircraft carrier, most likely an Essex or Midway class during the war. The USS Enterprise was the most decorated USN warship of WWII, but was a Yorktown class carrier. *It was the "Constitution"*
The USS Missouri (BB-63), which was a US Iowa-class battleship, was 887.2 feet long. A link can be found below to check facts and learn more.
The four battleships of the World War II-era USS Iowa class (includes Iowa, New Jersey, Missouri and Wisconsin) are the largest "battleships" built by the United States. However, modern US nuclear-powered aircraft carriers, including the USS Enterprise and the USS Nimitz-class carriers, are the largest "warships" built by the US. The Iowa-class battleships are approximately 890 feet long and displace some 45,000 tons. The Nimitz-class carriers are approximately 1100 feet long and displace some 90,000 tons.Adding on to the last answer, the Montana class battleships would have been the largest US battleship class, weighing in at 72,000 tons, but were canceled in favour of the Essex Class Carriers. But to be exact, the largest battleship of the US Navy, not battleship class was the USS Missouri, weighing in at 45,700 tons, 890 feet, just 700 tons heavier and 3 feet longer than the other Iowas. The extension allowed it to fit a couple more anti-aircraft missiles during the 1980's.
Habsburg class battleship was created in 1900.
It was a Pennsylvania Class Battleship.
The USS New Jersey, an Iowa class battleship, is the last warship to have fought as a traditional all gun battleship & the only battleship to have fought in the Vietnam War.
The Yamato-class battleships were bigger and more heavily armed than any battleship in the US Navy. The US focused more on aircraft carriers and submarines for naval warfare, as they were seen as more effective in the changing dynamics of naval combat during World War II. Additionally, the construction of such large battleships was costly and resource-intensive, which may have influenced the US decision-making.
