USS Vermont (SSN-792) is a Virginia-class nuclear powered attack submarine in the United States Navy. She is the 19th boat of the class and the third vessel of the Navy to be named for the U.S. state of Vermont. Then Secretary of the Navy, Ray Mabus, announced her name on 18 September 2014.[8]

Vermont was part of a $17.6 billion contract awarded by the U.S. Navy to General Dynamics Electric Boat to construct ten Virginia-class submarines, the first of the Block IV type.[7]

On 20 October 2018, Vermont was christened with a bottle of Vermont sparkling apple wine during a ceremony held at the Electric Boat facility in Groton, Connecticut.[9][10] She was delivered to the United States Navy on 17 April 2020.[11]

Service history[]
