Mamoli USS Constitution Cross Section
U. S. S. CONSTITUTION, an American frigate with 54 guns, was launched on 21st October 1797. She had bigger dimensions, sails and equipment than the contemporary ships of the same class. Her strong construction earned her the name of Old Ironsides. The Congress of the United States authorized the construction of Constitution and of two other ships in order to strengthen the American Navy and to protect trade with Europe, which were too often endangered by the more and more numerous attacks of enemy units.
