(Associated Press) BOSTON -- The world's oldest commissioned warship will sail under its own power for just the second time in more than a century to commemorate the battle that won it the nickname "Old Ironsides."
The USS Constitution, which was first launched in 1797, will be tugged from its berth in Boston Harbor on Sunday to the main deepwater pathway into the harbor. It will then set out to open seas for a 10-minute cruise.
The short trip marks the day two centuries ago when the Constitution bested the British frigate HMS Guerriere in a fierce battle during the War of 1812.
