The last time the battle ship was a contender for the title of main battery of the fleet was the start of WW II. During that war the aircraft carrier rose to premier status.

Below is a link to an illustrated list of American battleships. This site presents an unusual opportunity to visually observe the technological evolution of the steel motorized battle ship from the late 19th century to the mid 20th. Below is the link.
