USS Constitution gets underway for her first turnaround cruise of 2012. The underway commemorated the 70th anniversary of the Battle of Midway and recognized members of the Wounded Warrior Project. Constitution is the world's oldest commissioned warship afloat. She defended the sea lanes against threat from 1797 to 1855, much like the mission of today's Navy.
