USS Michigan (SSGN-727)

USS Michigan (hull number SSBN-727/SSGN-727) is an Ohio-class nuclear-powered guided missile submarine (SSGN), converted from a ballistic missile submarine (SSBN), that is part of the United States Navy. She is the third vessel to bear the name of the U.S. 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. She was originally designed and commissioned as a ballistic missile submarine (SSBN) capable of deploying 24 Trident II submarine-launched ballistic missiles (SLBM) with nuclear warheads.

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.

Post-conversion

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 boat also completed several theater security cooperation engagements with Pacific Rim nations.

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.
