HMSUnbeaten was aU-classsubmarine, of the second group of that class, built byVickers-Armstrongs,Barrow-in-Furness. She waslaid down on 22 November 1939 and wascommissioned on 10 November 1940. So far she has been the only ship of theRoyal Navy to bear the nameUnbeaten.
Unbeaten spent much of her career operating in theMediterranean, where she sank the Italian sailing vessel V 51 /Alfa, theVichy-French merchantPLM 20, theItalian submarine Guglielmotti and the German submarineU-374. She also claimed to have sunk two sailing vessels with gunfire on 15 July 1941 at Marsa Zuag roads, Libya, but Italian sources only confirm damage to one fishing vessel.[1]
Unbeaten also lightly damaged the Italian merchantVettor Pisani on 16 March 1942.[2] She also unsuccessfully attacked the Italian merchantSilvio Scaroni, the Italian troop transportEsperia and a large Italian troop transport, thought to be eitherOceania orNeptunia.[1]
After a refit in Chatham, and subsequent workup,Unbeaten was attached to the Third Submarine Flotilla in Scotland. Having sailed fromHoly Loch on her last patrol,Unbeaten completed Operation Bluestone, landing an agent in Spain nearBayona. She then completed her patrol in theBay of Biscay and was returning to the United Kingdom when she went missing. It is believed that she was probably attacked and sunk in error by aRoyal Air ForceWellington of No. 172 Squadron,Coastal Command in the Bay of Biscay on 11 November 1942. She was lost with all hands.[3]
