USS Massachusetts (SSN-798)

USS Massachusetts (SSN-798), is a Virginia-class nuclear powered attack submarine currently being built for the United States Navy. She is the twenty-fifth boat of the class and the eighth vessel to be named for the U.S. state of Massachusetts. Then Secretary of the Navy, Ray Mabus, announced the name on 8 November 2015 in an opinion piece for The Boston Globe.[3] She is the first vessel to be named after the Commonwealth since the now-preserved battleship USS Massachusetts (BB-59) was decommissioned in 1947.[4]
