German torpedo boat T11
The German torpedo boat "T11" was one of a dozen Type 35 torpedo boats built for the "Kriegsmarine" (German Navy) during the late 1930s. Completed in mid-1940, the boat was deployed in the English Channel later that year and returned to Germany in December. She then supported operations in the Baltic Sea after the start of Operation Barbarossa in June. "T11" was transferred to France at the end of the year and helped to escort a pair of battleships and a heavy cruiser through the Channel back to Germany in the Channel Dash in early 1942 . She then escorted German ships in Norwegian waters for several months and was placed in reserve when she returned to Germany. The boat spent all of 1943 and 1944 either refitting or assigned to the Torpedo School. "T11" returned to active duty at the beginning of 1945 and survived the war. The boat was allocated to the British after the war, but she was transferred to France in 1946. Unused by the French Navy, she was stricken from the Navy List in 1951 and subsequently scrapped. Design and description. The Type 35 was an unsuccessful attempt by the "Kriegsmarine" to  design a fast, ocean-going torpedo boat that did not exceed the displacement limit of the London Naval Treaty for ships that counted against the national tonnage limit. The boats had an overall length of and were long at the waterline. After the bow was rebuilt in 1941 to improve seaworthiness, the overall length increased to . The ships had a beam of , and a mean draft of at deep load and displaced at standard load and at deep load. Their crew numbered 119 officers and sailors. Their pair of geared steam turbine sets, each driving one propeller, were designed to  produce using steam from four high-pressure water-tube boilers which would propel the boats at . They carried enough fuel oil to give them a range of at . As built, the Type 35 class mounted a single SK C/32 gun on the stern. Anti-aircraft defense was provided by a single SK C/30 anti-aircraft gun superfiring over the 10.5 cm gun and a pair of C/30 guns on the bridge wings. They carried six above-water torpedo tubes in two triple mounts and could also carry 30 mines (or 60 if the weather was good). Many boats exchanged the  3.7 cm gun for another 2 cm gun, depth charges and minesweeping paravanes before completion. Late-war additions were limited to the installation of radar, radar detectors and additional AA guns, usually at the expense of the aft torpedo tube mount. Construction and career. "T11" was ordered on 29 June 1936 from DeSchiMAG, laid down at their Bremen shipyard on 1 July 1938 as yard number 938, launched on 1 March 1939 and commissioned on 24 May 1940. The boat was working up until July when she was transferred to the Skaggerak for convoy escort duties. On 18 September, "T11  was slightly damaged by bomb splinters when the Royal Air Force bombed Cherbourg, France. Several of her crew were wounded during the attack. She returned to Germany in December and was decommissioned for repairs that lasted until June 1941. The boat was recommissioned and assigned to the Baltic Sea where she escorted, together with her sister ships and , the light cruisers and as they supported German forces invading the Estonian islands of Ösel, Dagö and Muhu (Operation Beowulf) in mid-September. T11" and her sisters , , "T7", and "T8" were among the escorts for the Baltic Fleet, a temporary formation built  around the battleship , as it sortied into the Sea of Åland on 23–29 September, to forestall any attempt by the Soviet Red Banner Baltic Fleet to breakout from the Gulf of Finland. The boat was transferred to France around the beginning of 1942. As part of the preparations for the Channel Dash, the "Kriegsmarine" substituted a quadruple 2 cm mount for "T11"s aft torpedo tubes and added a 2 cm single mount at the bow to reinforce the boat's anti-aircraft suite. On the morning of 12 February 1942, the 2nd and 3rd Torpedo Boat Flotillas (with "T2", "T4 , T5", "T11", and , , , and respectively) rendezvoused with the battleships and and the heavy cruiser to escort them through the Channel to Germany. "T11"s torpedo tubes were replaced afterwards, although the quadruple mounting may have been moved to the aft superfiring position and she also may have kept her bow-chaser. She was transferred to Norway the following month and was one of the escorts for the badly damaged "Prinz Eugen" from Trondheim to Kiel on 16–18 May (Operation "Zauberflote" (Magic Flute)), together with "T12" and the destroyers and . "T11" returned to Germany that month and was placed in reserve until  the end of the year. The boat was recommissioned in January 1943 and was assigned to the Torpedo School in April. She began a refit in mid-1944 that lasted until December when she was assigned to the 3rd Torpedo Boat Flotilla in the Baltic. On 2 April 1945, "T11" was involved in a collision with the minesweeper "R 256" east of Bornholm Island, which was sunk by Soviet aircraft later that day. The torpedo boat was allocated to the British when the Allies divided the surviving ships of the "Kriegsmarine" amongst themselves in late 1945. The Royal Navy had no  interest in her and she was transferred to France in February 1946 and was renamed "Bir Hacheim" on 4 February. The boat was immediately placed in reserve until she was stricken on 8 October 1951 and subsequently scrapped.
