USS New Hampshire (SSN-778), a Virginia-class nuclear-powered attack submarine, is the fourth vessel of the United States Navy to be named for the state of New Hampshire. She is the first of the Virginia-class Block-II submarines to enter service. Her name was awarded to the submarine after a letter-writing campaign by the third-graders from Garrison Elementary School and sixth graders from Dover Middle School in Dover to their members of Congress, the state governor, and the Secretary of the Navy.[7]
