Construction work on USS Montana began in May 2015. The submarine was christened by the ship’s sponsor, former US Secretary of the Interior Sally Jewell, during a ceremony in September 2020.

USS Montana is the third of the 10-ship group of Virginia-class submarines known as Block IV.

Block IV submarines incorporate design changes focused on reduced total ownership cost. By making smaller-scale design changes, the navy is expected to increase the length of time between maintenance stops and increase the number of deployments.
