About 3 years for a WWII modern steel battleship.
Notes:
Note that most Battleships and Cruisers were produced before the war and many served through its entirety. [1]
With the Washington Naval Treaty of 1922, the major navies of the world scaled back their battleship programs, with numerous ships on all sides scrapped or re-purposed. With extensions, that treaty lasted until 1936, when the major navies of the world began a new arms race. Famous ships like Bismark, Prince of Wales, and Yamato were all launched in the next few years. [2]
About a year.
It took about 2 minutes for each of Admiral Togo's battleships to turn around (to maintain their capping of the "T" formation over the advancing Russian battleships).
Since I believe there is only one God, who has different names from different people, it took him 6 days to create the world.
