The world’s oldest commissioned naval ship afloat, the USS Constitution was relaunched last Sunday after completing an extensive restoration at the Charlestown Navy Yard in Boston, Massachusetts.
NBC News reports that about every 20 years the ship enters dry dock for below-the-waterline repairs. This time, the restoration included replacing 100 hull planks and installing 2,200 new copper sheets.
This video by CBS Boston has more about the relaunching:
The ship earned her nickname “Old Ironsides” during the war of 1812, after she defeated the United Kingdom’s warship HMS Guerriere in a battle approximately 400 miles southeast of Halifax, Nova Scotia.
