USS CONSTITUTION. The Constitution--called Old Ironsides because cannonballs could not penetrate her tough oak sides--was one of the first of the original six frigates that made up the U.S. Navy. A 44-gun frigate built at the Edmond Hartt Shipyard, Boston, MA, in 1797.
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.
