She was launched in 1863, laid up in 1878 and sold for breaking in 1884, having displayed serious limitations as a warship.
CSS Webb, a 655-ton side-wheel steam ram, was originally built in New York City in 1856 as the civilian steamship William H. Webb.

The Marietta-class monitors were a pair of ironclad river monitors laid down in the summer of 1862 for the United States Navy during the American Civil War. Construction was slow, partially for lack of labor, and the ships were not completed until December 1865, after the war was over. However the navy did not accept them until 1866 and immediately laid them up. They were sold in 1873 without ever having been commissioned.
HMS Vesuvius was initially a Steam Vessel second class designed by Sir William Symonds, Surveyor of the Navy, and built at Sheerness. She was commissioned and participated in the bombardment of Acre in 1840, during the Russian War she was in the Black Sea and the Sea of Azov in 1855. Her last overseas posting was in the West Indies. She was sold for breaking in June 1865.
