The nuclear-powered Improved Los Angeles Class (SSN-688i) submarine USS Miami (SSN 755) was ordered in 1983 and built by General Dynamics Electric Boat. She was commissioned in 1990, is homeported in Groton, CT, and was the focus of Tom Clancy’s 1993 non-fiction book Submarine: A Guided Tour Inside a Nuclear Warship. In May 2012, a civilian shipyard worker in Portsmouth Naval Shipyard caused a fire, which quickly spread through its 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.
