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.
Six frigates were built, and The USS Constitution, in particular, was designed to be bigger, faster, and more impenetrable than other ships of her day. Our first president, George Washington, had the honor of naming the ship and chose to name her after the U.S. Constitution.
