Navy Decommissions USS Miami at Portsmouth Naval Shipyard

The U.S. Navy decommissioned the USS Miami on March 28 in a ceremony at the Portsmouth Naval Shipyard.

The Los Angeles-class attack submarine, first commissioned in 1990, was affectionally known as "Big Gun" and had a storied service record. It was the first nuclear-powered submarine to transit the Suez Canal. In the late 1990s, it launched Tomahawk cruise missiles during Operation Desert Fox in Iraq and Operation Allied Force in Kosovo, according to the U.S. Navy.

The "Big Gun" moniker was bestowed after the submarine became the first sub since World War II to fire ordnance during combat in two different theaters, according to Navy chronicles of its service.

The submarine's end was precipitated by an act of arson, in which a civilian worker at the shipyard set fire inside it and caused an estimated $400 million in damage in May of 2012.
