That is a fact. They are now is special storage, as museums. Go see one. Its the experience of a life time. If you can't find a battleship, see your nearest vintage WWII ship.
Technically - the USS Texas is of WW1 vintage. Great ship to visit if you have the chance. She is the last dreadnought era battleship left in the world I believe.
It's a shame the British didn't save HMS Warspite (also of the same era) as a museum ship. Not many battleships had a history as rich as hers (she was at Jutland, D-Day, and a lot more).
