A fire raged through the nuclear-powered Los Angeles class fast attack submarine USS Miami on Wednesday, 23rd of May, 2012, while sitting in a dry dock at the Portsmouth Naval Shipyard in Kittery, Maine. According to US Navy sources, the submarine’s nuclear reactor was not in operation at the time of the fire and no weapons were aboard. A civilian shipyard worker caused the fire, which quickly spread through the submarine’s forward compartments. It took the efforts of more than 100 firefighters to save her. The cost of the necessary facelifts and fixes was so high that the Navy eventually decided to retire the boat.  After 23 years of service, the Navy formally decommissioned USS Miami on March 28, 2014, during an indoor ceremony at Portsmouth Naval Shipyard in Kittery, Maine.
