USS Constitution, ‘Old Ironsides’, will enter dry dock May 18 for a nearly three year restoration with most of the work being done below the waterline and the bow area. The timeline of events leading up to the ship’s dry docking can be found below. The ship will be moved into position on May 15, the dry dock flooded on May 17 then Constitution will enter the dry dock on May 18 at 10:20 p.m. Why is this important? USS Constitution is the only survivor of the U.S. Navy’s original six frigates. Her mission was to keep the sea lanes open for commerce, fight pirates, land Marines in trouble spots (…to the shores of Tripoli…), and prevent the slave trade. The U.S. Navy carries out similar missions today.
