HMS Nankin was a fourth rate frigate of the Royal Navy. It was built by Oliver Lang [1] in Woolwich dockyard in 1850 and named after the city of Nanking (now named Nanjing). It could hold 500 men and 50 guns, including a variety of guns, ranging from 32-pounder to 68-pounder. For structural reasons, the navy decided that eight guns would be mounted on the gangways amidships, but this also meant that no spar-decked frigates mounted guns in its waists. [2] It was involved in the Second Opium War from 1856 to 1859, but was then moved back to Pembroke dock. It was sold in 1895. [3]
