The first USS New Hampshire of the United States Navy was originally to be the 74-gun ship of the line Alabama, but remained on the stocks for nearly 40 years, well into the age of steam, before being renamed and launched as a stores and depot ship during the American Civil War. She was later renamed to USS Granite State.
PCU New Hampshire (SSN-778), a Virginia-class submarine, is slated to be the fourth ship of the United States Navy to be named for the state of New Hampshire, though one of her predecessors, BB-70, existed only on paper (authorized, but cancelled before keel laying). The name was awarded to the submarine after a letter writing campaign by the third-graders from Garrison Elementary School in Dover to their Congressmembers, the state Governor, and the Secretary of the Navyhttp://www.fosters.com/apps/pbcs.dll/article?AID=/20051222/NEWS01/112220123&SearchID=73230335949234.
