The dock landing ship USS Oak Hill (LSD-51) sails under the Francis Scott Key Bridge in support of Baltimore's Star-Spangled Spectacular. This event celebrates the bicentennial of the Battle of Baltimore, which provided the backdrop for Francis Scott Key's famous poem, "Defence of Fort McHenry," which later became America's national anthem. More than 30 ships from the U.S. and foreign nations, and the U.S. Navy's Blue Angels aircraft will be on display and open to the public.
