Main Page | See live article | Alphabetical index The British submarine P.311 was the only Royal Navy T-Class submarine not to be given a name. She was to have received the name HMS Tutankhamen but was lost before this was formally done. 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. P.311 was a group 3 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 anti-aircraft gun, the other being HMS Trespasser. She joined the 10th Submarine Flotilla at Malta in November 1942, and was lost with all hands between 30 December and 8 January 1942 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. It was assumed that she was mined. This article is from Wikipedia. All text is available under the terms of the GNU Free Documentation License.
