The USS United States was a pioneering wooden-hulled, three-masted heavy frigate of the United States Navy, notable as the first ship of the U.S. Navy, launched on May 10, 1797. Designed by Joshua Humphreys, she was built at Humphrey's shipyard in Philadelphia, Pennsylvania. Her construction was characterized by a deep keel, a narrow beam, and a diagonal scantling framework, which conferred exceptional strength and allowed her to carry heavy armament—a necessity given her role as a capital ship in the young navy. The frigate measured approximately 1,582 tons burthen and was one of the larger, more heavily armed frigates of her period, typically mounting over 50 guns, including 24-pounder cannons, 42-pounder carronades, and an 18-pounder long gun, although her official rating was 44 guns. Launched in 1797, USS United States quickly became a symbol of American naval ambition, initially tasked with protecting merchant shipping during the Quasi-War with France. She was actively engaged in naval operations along the Atlantic and Caribbean, capturing French privateers such as Sans Pareil, Jalouse, and La Tartueffe, and participating in actions against French vessels and shore batteries. Her notable combat achievement was her victory over HMS Macedonian in 1812 during the War of 1812, where she dismasted and compelled the surrender of the British frigate, an event celebrated as a significant American naval victory. Throughout her long service life, USS United States served in various roles—blockade, convoy, and diplomatic missions—including her presence in the Mediterranean, Pacific, and along the Atlantic coast. She also carried prominent figures and was involved in early American naval encounters with British and Mediterranean forces. Her significance lies in her being the first of the original six frigates authorized by the Naval Act of 1794, embodying Humphreys' innovative design philosophy aimed at creating a navy capable of overpowering European frigates and defending American interests. Eventually, her service ended with her capture by Confederate forces in 1861, after which she was renamed CSS United States and used as a harbor defense vessel. She was scuttled and later raised by Union forces, but she was ultimately broken up in 1865, marking the end of her historic career as a symbol of early American naval enterprise.
