HMS P311 was a T-class submarine of the Royal Navy, the only boat of her class never to be given a name. She was to have received the name Tutankhamen but was lost before this was formally done. P311 was a Group 3 T-class boat built by Vickers-Armstrong at Barrow-in-Furness and commissioned on 5 March 1942 under the command of Lieutenant R.D. Cayley. She was one of only two T-class submarines completed without an Oerlikon 20 mm anti-aircraft gun, the other being HMS Trespasser.
Naming
The Prime Minister, Winston Churchill had minuted the Admiralty on 5 November 1942, 19 December and again on 27 December, saying that all submarines should have names. In the final minute, he provided a list of suggestions and insisted that all unnamed submarines be given names within a fortnight. P311 was to be assigned the name Tutankhamen, after the Egyptian king. She would have been the only vessel of the Royal Navy, before or since, to bear the name. She was lost in the Mediterranean between late December 1942 or early January 1943, before the new name could be formally assigned. She therefore never received the name Tutankhamen, and is officially designated as P311.[1]
Career
She joined the 10th Submarine Flotilla at Malta in November 1942, and was lost with all hands between 30 December 1942 and 8 January 1943 whilst en route to La Maddalena, Sardinia where she was to attack two Italian 8-inch gun cruisers using Chariot human torpedoes carried on the casing as part of Operation Principle. She was reported overdue on 8 January 1943 when she failed to return to base. It was assumed that she was mined.[2]
