USS Michigan (SSGN 727)

USS Michigan (SSGN 727) is the second submarine of the Ohio-class of ballistic missile submarines (SSBNs) and guided missile submarines (SSGNs), and the third U.S. Navy ship to bear the name.

Michigan was launched on April 26, 1980, christened by Margaret Nedzi, the wife of Rep. Lucien Nedzi (D-Mich.), and was commissioned nearly 30 months later on Sept. 11, 1982. Capt. W.E. Rickman (Blue Crew) and Capt. F.M. Conway III (Gold Crew) were Michigans first commanding officers.

Michigan was built to carry the Navys third generation submarine-launched ballistic missile (SLBM), the Trident C-4. After arriving in Bangor in March 1983, Michigan would carry out her primary mission of deterrence for nearly 20 years, conducting more than 60 strategic deterrent patrols.

.President Donald Trump is escalating tensions with Russia by deploying two U.S. nuclear submarines to the region ahead of a Friday ceasefire deadline for Ukraine.

-The move was a response to inflammatory rhetoric from Russian official Dmitry Medvedev, but nuclear security experts have labeled Trump’s action as “risky,” warning it could lead to a dangerous miscalculation.

-While the Kremlin urged caution with “nuclear rhetoric,” its foreign ministry simultaneously announced it is abandoning its moratorium on deploying nuclear-capable intermediate-range missiles in Europe, raising the stakes in the standoff even higher.

..USS MICHIGAN is the third United States Navy vessel to be named after the state of Michigan.

The first USS MICHIGAN (1843-1922) was the first iron warship in the U.S. Navy.

The second USS MICHIGAN (BB-27) was a battleship built by the New York Shipbuilding Company. Laid down on 17 December 1906, launched on 26 May 1908, and commissioned on 4 January 1910, she served until her decommissioning on 11 February 1922 at the Philadelphia Navy Yard.

..

USS Michigan (SSGN 727) rejoined the fleet on this day in 2007, in a ceremony that brought her "to life" as a guided missile submarine. For 21 years, Michigan made strategic deterrent patrols as a ballistic missile submarine, until Navy requirements and nuclear treaty terms reduced the need for 18 Ohio-class submarines.

Four ballistic missile subs — Ohio, Michigan, Florida, and Georgia — were chosen for conversion to a guided missile platform. Michigans conversion was carried out by the Puget Sound Naval Shipyard between February 2004 and November 2006.
