The third Ocean was originally ordered to be built as a wooden screw ship intended to carry 91 guns. However, the order was changed and she was eventually launched in 1863 as an ironclad[?] of 24 guns. In the late 1860s she served as flagship to the Commander in Chief of the China Station[?] and after an active life of only six years, was paid off in 1872.
