KITTERY, Maine - A nuclear powered submarine heavily damaged by a fire set by a shipyard worker has departed Portsmouth Naval Shipyard.
A Navy spokeswoman says workers have completed the inactivation of the USS Miami, which was towed from the shipyard on Friday. Two Navy ships are assisting in towing the sub to Puget Sound Naval Shipyard in Washington State, where it'll be cut up for scrap.
The fire in May 2012 turned into an inferno that required 12 hours and more than 100 firefighters to douse.
A former shipyard worker is serving a 17-year prison sentence for setting the blaze.
After the fire, the Navy intended to return the Los Angele-class attack submarine to the fleet after extensive repairs. But it decided to scrap the submarine when estimated repair costs grew.
