HMS Proteus (N29)
HMS Proteus was a Parthian-class submarine designed and built by Vickers Shipbuilding and Engineering in Barrow-in-Furness for the Royal Navy, and was launched on 22 August 1929. Like other submarines in her class she served in China before the war.
Based at Alexandria Proteus engaged and sank 17 German and Italian merchant ships, troopships, tankers and torpedo boats during her service in the Mediterranean in the Second World War. Her attack on the troop transport ship Ithaka is thought to be the first radar guided submarine attack.
HMS Proteus was the longest surviving Parthian-class submarine and the only Parthian class submarine to survive the war.
Proteus had a total of nine commanders during the war.
