Minnesota was laid down on 20 May 2011, and christened on 27 October 2012 in a ceremony attended by many top ranking officials in the U.S. Navy and Congress.[1][3][4]

On 6 June 2013, Huntington Ingalls Industries announced that Minnesota had been delivered to the Navy, nearly 11 months ahead of schedule.[5][6] Minnesota was commissioned on 7 September 2013.

After commissioning, Minnesota remained at the General Dynamics Electric Boat shipyards in Groton, CT for over two years. A broken pipe joint was discovered in the vessel's nuclear reactor. The pipe had been tampered with in order to make the part appear within specifications.[7][8] Although a failure of the pipe would not result in a reactor incident, it would affect the reactor's ability to produce steam used for propulsion.[8] The same issue has been discovered on two other boats in the class. A Navy investigation determined that two other ships had the same issue, and the U.S. Justice Department commenced an investigation of the contractor responsible for the defective parts.[7][8]

On 27 May 2016, Minnesota left the Electric Boat shipyards for her home port, Naval Submarine Base New London in Groton, CT, to prepare for fleet operations.[9]
