A shipyard worker who set fire to rags aboard a nuclear submarine because he wanted to go home was sentenced to a little more than 17 years in federal prison Friday for the blaze that transformed the vessel into a fiery furnace, injured seven people and caused $450 million in damage, according to AP. Casey James Fury also was ordered to pay $400 million in restitution. The judge imposed the sentence under a plea agreement that limited his time in prison to roughly 15 to 19 years for arson. The 25-year-old Fury pleaded guilty to setting the May 23 fire while the submarine was undergoing a 20-month dry dock overhaul at Portsmouth Naval Shipyard in Kittery. The civilian painter and sand blaster told authorities that he needed to go home because he was suffering from an anxiety attack and had no more vacation or sick leave. He said he never envisioned such extensive damage when he used a lighter to set fire to a plastic bag of rags that he left on a bunk in a state room. The blaze quickly grew into an inferno spewing superheated smoke that billowed from hatches. It took 12 hours for more than 100 firefighters to save the submarine. Seven people were hurt, the Navy has said. -- SPA 18:16 LOCAL TIME 15:16 GMT تغريد
