USS Michigan (SSBN-727/SSGN-727) is the second Ohio-class nuclear-powered guided missile submarine in the United States Navy. She is the third ship to bear the name of the state of Michigan.

Construction and commissioning[edit]

Michigan was constructed at the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut and was commissioned on 11 September 1982. Michigan arrived in Bangor, Washington on 16 March 1983 and completed sixty-six Strategic Deterrent Patrols.

Conversion to SSGN[edit]

As of June 2007, Michigan has been converted to an SSGN at the Puget Sound Naval Shipyard.[4] Her hull classification symbol then changed from SSBN-727 to SSGN-727. See the section on SSGN conversions of the Ohio-class article for more information.


On 12 December 2009, Michigan returned to Naval Base Kitsap, her home base, completing her first deployment after the SSGN conversion. The deployment began 10 November 2008, and included numerous missions. The ship also completed several theater security cooperation engagements with Pacific Rim nations.[5]

On 28 June 2010, Michigan was one of three Ohio-class submarines involved in a US response to Chinese missile testing in the contested East China Sea. Michigan, Ohio, and Florida all surfaced simultaneously in the waters of South Korea, the Philippines, and the British Indian Ocean Territory respectively. China promptly ceased all missile testing in the region.[6][7]
