The USS Princeton was a pioneering screw steam warship of the United States Navy, launched on September 5, 1843, and constructed at the Philadelphia Navy Yard. Designed by the Swedish inventor John Ericsson, the vessel measured approximately 954 long tons (969 metric tons) and featured innovative engineering for its time. Its propulsion system consisted of two vibrating lever engines, built by Merrick & Towne, which powered a 14-foot (4.3-meter) six-bladed screw propeller. These engines were notable for being mounted below the waterline to minimize vulnerability to enemy fire. The ship's armament included twelve 42-pound (19 kg) carronades within its iron hull, along with a large, wrought-iron muzzle-loading long gun called the "Oregon gun." The Oregon gun was a 12-inch (300 mm) smoothbore cannon capable of firing a 225-pound (102 kg) projectile over 5 miles (8 km). It was constructed using a "built-up" method involving red-hot iron hoops, which increased its strength. However, a second, larger gun called "Peacemaker," designed to match the Oregon gun, was constructed and mounted in 1844. Unfortunately, during a demonstration cruise on February 28, 1844, while firing Peacemaker, the gun burst, killing six people, including Secretary of State Abel P. Upshur and Secretary of the Navy Thomas Walker Gilmer, and injuring others, including Captain Stockton and Senator Benton. This disaster, known as the Peacemaker explosion, significantly damaged the ship's reputation and led to the cessation of similar large gun projects. The USS Princeton served with the Home Squadron and later in the Mediterranean between 1845 and 1849. Following her active service, she was found to require extensive repairs and was ultimately broken up at the Boston Navy Yard in late 1849. The engine design pioneered on Princeton influenced subsequent ships, including the second USS Princeton built in 1851. The ship holds historical significance as the first vessel with submerged screw propellers powered by Ericsson's engines, and the Peacemaker disaster prompted advancements in naval artillery manufacturing. Her figurehead and the "Oregon gun" remain notable artifacts of early American naval innovation.
