Massachusetts (SSN-798), a Virginia-class submarine, will be the seventh U.S. Navy ship named for the state of Massachusetts. Secretary of the Navy Ray Mabus announced the name on November 8, 2015 in an opinion piece for The Boston Globe.[2] It is the first ship named after the Commonwealth of Massachusetts since the battleship USS Massachusetts (BB-59) was decommissioned in 1947.[3]
