USS Michigan (SSGN-727)

USS Michigan (SSBN-727/SSGN-727) is the second 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
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
As of June 2007, Michigan has been converted to an SSGN at the Puget Sound Naval Shipyard. 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.
