USS Constitution. Launched in Boston in 1797, the oldest commissioned warship afloat earned her nickname Old Ironsides during the War of 1812 when she fought the British frigate HMS Guerriere. During this historic battle, cannonballs fired at USS Constitution appeared to bounce off, causing one of her crew to remark that her sides were made of iron.
The USS Constitution is the traditional flagship of the US Navy. And it is still in commission and manned by a US Navy crew. USS Constellation CVN-64 was given the moniker of America s Flagship by President Ronald Reagan. It is currently decommissioned and has been replaced in the fleet by the USS Ronald Reagan CVN-76.
