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.[9]

Vermont was part of a construction contract, worth US$17.6 billion, awarded to General Dynamics Electric Boat to build ten Virginia-class submarines, the first of the Block IV type.[5]

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.[10][2] She was delivered to the Navy on 17 April 2020, and commissioned on 18 April 2020.[11]

On July 27, 2023, Vermont arrived in her new home port of Pearl Harbor, HI. The submarine is assigned under Submarine Squadron ONE.[12]
