About this Unit
USS Michigan (SSBN-727/SSGN-727) is an Ohio-class submarine commissioned into the United States Navy in September 1982. Originally built as a ballistic missile submarine (SSBN), Michigan conducted strategic deterrent patrols throughout the Cold War, supporting America's nuclear triad. In 2007, Michigan was converted to a guided missile submarine (SSGN), enhancing her capabilities to launch Tomahawk cruise missiles and support special operations forces. Since then, USS Michigan has played a critical role in power projection and special warfare missions in the Pacific theater.
