USS Miami (SSN-755)

USS "Miami" (SSN-755) was a United States Navy attack submarine. She was the third vessel of the U.S. Navy to be named after Miami, Florida. "Miami" was the forty-fourth "Los Angeles"-class (688) submarine and the fifth Improved "Los Angeles"-class (688I) submarine to be built and commissioned. The contract to build her was awarded to the Electric Boat division of General Dynamics Corporation in Groton, Connecticut, on 28 November 1983 and her keel was laid down on 24 October 1986. She was launched on 12 November 1988 and commissioned on 30 June 1990 with Commander Thomas W. Mader in command.
On 1 March 2012, "Miami" pulled into the Portsmouth Naval Shipyard in Kittery, Maine, for a scheduled 20-month Engineered Overhaul (EOH) and system upgrades. On 23 May, a shipyard employee started a fire that spread to crew living, command and control, and torpedo spaces. Repairs were initially estimated to require three years and $450 million, a figure that was later revised to a range of $450 million to $700 million. 
On 6 August 2013, Navy officials said that due to budget cuts the vessel would not be repaired. The submarine was placed on the inactive list, then decommissioned on 28 March 2014.

1999.
"Miami" became the first submarine to conduct combat operations in two theaters since World War II (Operation Desert Fox and Operation Allied Force).
2012 fire.
At 5:41 p.m. EDT on 23 May 2012, fire crews were called with a report of a fire on "Miami" while being overhauled at the Portsmouth Naval Shipyard in Kittery, Maine. At the time, the submarine was on a scheduled 20-month maintenance cycle, indicating that she was undergoing an extensive overhaul called an "Engineering Overhaul". The national media reported that seven firefighters had been injured. One crew member suffered broken ribs when he fell through a hole left by removed deck plates during the fire. It took firefighters 12 hours to extinguish it.
Originally, the U.S. Navy reported that the fire started when an industrial vacuum cleaner used "to clean worksites on the sub after shipyard workers’ shifts" sucked up a heat source that ignited debris inside the vacuum. On 23 July 2012, however, civilian painter and sandblaster Casey J. Fury was indicted on two counts of arson after confessing to starting the fire. Fury admitted to setting it by igniting some rags on the top bunk in a berthing compartment. He claimed to have started it in order to get out of work early. On 15 March 2013, he was sentenced to more than 17 years in federal prison and ordered to pay $400 million in restitution.
The debate over whether to repair or scrap the submarine lasted more than a year. Within a month of the fire, Maine Senators Susan Collins and Olympia Snowe advocated repairing her. In July 2012, Navy leaders asked Congress to add $220 million to the operations and maintenance budget for emergent and unfunded ship repairs to help repair "Miami". In August, the Navy decided to repair the boat for an estimated total cost of $450 million. The repair cost was expected to be trimmed by using spare parts from the recently decommissioned and by repairing rather than replacing damaged hull sections, as had been done with another "Los Angeles"-class boat, . But both of these approaches proved unworkable with the newer "Miami." As well, a detailed assessment raised the estimated repair bill to $700 million.
On 6 August 2013, the U.S. Navy announced its intention to decommission "Miami", concluding the cost was more than it could afford in a time of budget cuts. The sub was officially decommissioned on 28 March 2014, to be disposed of via the nuclear Ship-Submarine Recycling Program.
