The USS Missouri (1841) was a pioneering sidewheel steam frigate built for the United States Navy, representing one of the earliest efforts to modernize naval propulsion. Constructed at the New York Navy Yard, she was laid down circa 1840, launched on January 7, 1841, and commissioned in 1842. The vessel measured approximately 229 feet (70 meters) in length, with a beam of 40 feet (12 meters) and a mean draft of 19 feet (5.8 meters). Her hull was constructed from live oak, subdivided by four iron watertight bulkheads to enhance structural integrity and prevent hogging. To accommodate her engines, coal stores, and provisions, she was designed with an overall size comparable to the 120-gun USS Pennsylvania, making her one of the longest ships in the fleet at the time. Missouri was powered by inclined engines, a design chosen to investigate different propulsion methods. She featured four copper boilers driving two inclined, direct-acting engines with a 10-foot stroke and large cylinders, which turned her twin paddle wheels, each 28 feet tall and 11 feet wide, producing approximately 517 indicated horsepower and achieving speeds of 7 to 10 knots. Her propulsion system was designed by Charles Copeland and built at the West Point Foundry. Her armament comprised four 8-inch Paixhan guns on each broadside and two 10-inch bow-mounted pivot guns, all positioned on the open gun deck. The ship was rigged with a barque sail plan covering 19,000 square feet, although her sail efficiency was limited due to the engine and funnel placement. Her service history was marked by notable achievements, including conducting the U.S. Navy’s first steam-powered Atlantic crossing in 1843, from the U.S. East Coast to Egypt via Gibraltar. This voyage demonstrated the viability of steam propulsion for ocean-going warships and signified a shift toward modern naval technology. However, her career was marred by the catastrophic fire at Gibraltar harbor in 1843, caused by turpentine ignition, which led to her destruction after her magazine detonated. The loss prompted significant naval reforms, including the establishment of the U.S. Navy's Engineer Corps. Despite her tragic end, USS Missouri’s innovative design and pioneering steam-powered operations contributed to the gradual transition from sail to steam in the U.S. Navy, marking her as a vessel of maritime technological significance in mid-19th-century naval history.
