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.
Celebration: The USS Constitution sets sail under her own power today for the first time since 1997 to commemorate the 200th anniversary of her victory over HMS Guerriere during the War of 1812.
