'''HMS ''Upstart'' (P65)''' was a [[Royal Navy]] [[British U class submarine|U-class]] [[submarine]] built by [[Vickers|Vickers-Armstrong]].  So far she has been the only ship of the Royal Navy to bear the name ''Upstart''. After the war, she was loaned to the [[Greek Navy]] and renamed '''''Amfitriti'''''.

==Career==

===Wartime===

''Upstart'' spent most of her wartime career operating off the south coast of France, where she sank the French fishing vessels ''Grotte de Bethlehem'' and ''Torpille'', the German auxiliary minelayer ''Niedersachsen'' (the former French ''Guyane'') and the German merchant ''Tolentino'' (the former French ''Saumur'').  She also launched failed attacks against the French merchant ''Medjerda'' and the Italian merchant ''Pascoli''.

===Greek service===

{{other ships|Greek submarine Amfitriti}}

''Upstart'' survived the war and was loaned to the [[Greek Navy]] in 1945, where she was renamed ''Amfitriti''.  She served with the Greek Navy for seven years, and was returned to the Royal Navy in 1952.  She was subsequently sunk as an ASDIC target off the [[Isle of Wight]] on 29 July 1959.
