From the July 24, 2017, USA Today "The USS Constitution -- 'Old Ironsides' -- is back afloat again" by Matthew Diebel.
The world's oldest commissioned warship, launched in 1797, is afloat again after a $12 million project which replaced most of its copper cladding with 2,200 sheets, repairing outside wooden planks and rebuilding its 42 gun carriages.
Refurbishing of the rigging and masts will be done before the ship reopens for visitors in August. The ship received its name from George Washington and won three major ship-to-ship victories in the War of 1812.
It remained on active duty until 1855. After that it became a training ship for the USNA then a touring national landmark. Since 1934 it has been based at Charleston Navy Yard in Boston.
