HMS Pandora (N42)
 HMS Pandora was a British Parthian-class submarine commissioned in 1930 and lost in 1942 during the Second World War. This class was the first to be fitted with Mark VIII torpedoes. On 4 July 1940 she torpedoed and sank the French sloop Rigault de Genouilly off the Algerian coast. In an extension of the Lend-Lease program Pandora along with three other British and French submarines was overhauled at Portsmouth Naval Shipyard in the United States.
