German torpedo boat T23

German torpedo boat T23 was a Type 1939 torpedo boat built for the Kriegsmarine during World War II. Completed in late 1942, she served primarily in the English Channel and the Bay of Biscay, engaging in minelaying operations, escort duties, and several naval battles against Allied forces. The vessel survived the war and was allocated to the French Navy as a war reparation, serving until the mid-1950s.

Design and description

The Type 1939 torpedo boat was a larger and more heavily armed design compared to earlier German torpedo boats, intended to function as a small destroyer. Displacing 1,294 tons at standard load and 1,754 tons at deep load, T23 had an overall length of 102.5 meters, a beam of 10 meters, and a draft of 3.22 meters. Her propulsion system consisted of two Wagner geared steam turbine sets, driving two shafts, which were fed by steam from four Wagner-brand water-tube boilers. This machinery was designed to generate 32,000 shaft horsepower for a top speed of 33.5 knots. The ship carried a maximum of 306 tonnes of fuel oil, giving her a range of 2,400 nautical miles at 19 knots. Her crew numbered 206 officers and sailors.

The ship's main armament consisted of four 10.5 cm SK C/32 naval guns in single mounts, protected by gun shields. Anti-aircraft defense was provided by four 3.7 cm 3.7 cm SK C/30 and six 2 cm 2 cm Flak 30/38/Flakvierling guns. She was also equipped with six 533-millimeter torpedo tubes in two triple mounts on the main deck, and could carry up to 30 naval mines. For anti-submarine warfare, she was fitted with four depth charge launchers.

Construction and career

T23 was ordered on 10 November 1939 from Schichau-Werke at their Elbing shipyard, laid down as yard number 1491. She was launched on 14 June 1942 and commissioned on 14 September 1942. After working up in the Baltic Sea, she was assigned to the 5th Torpedo Boat Flotilla operating from occupied France. Her early duties involved escorting German blockade runners, U-boats, and auxiliary cruisers through the western approaches, as well as conducting offensive minelaying sorties off the coast of Brittany and in the English Channel.

Service history

T23 saw extensive action in the English Channel and the Bay of Biscay. In early 1943, she participated in the Channel Dash aftermath operations, escorting critical vessels. On 28 December 1943, she was part of the German force that fought in the Battle of the Bay of Biscay, where she helped repel an attack by the British Light cruisers HMS ''Glasgow'' and HMS ''Enterprise'', contributing to the safe passage of a German blockade runner. Throughout 1944, her activities intensified following the Allied invasion of Normandy. She engaged in frequent skirmishes with Allied destroyers and motor torpedo boats, such as those from the Royal Canadian Navy, and conducted hazardous minelaying missions off Le Havre and Cherbourg.

One of her most significant engagements was the Battle of Sept-Îles on 22 October 1943, where the 4th and 5th Torpedo Boat Flotillas, including T23, successfully defended against a superior British force, damaging several enemy ships. Later, during the Normandy landings, T23 was involved in the failed German naval counter-attack on 6–7 June 1944, engaging Allied forces off the Sword Beach sector. She continued escort and patrol duties along the French coast as German forces retreated, participating in the evacuation of Channel ports in August 1944.

Fate

Following the German surrender in May 1945, T23 was found in Kiel and taken as a prize of war by the Allies. Under the terms of war reparations, she was allocated to the French Navy in January 1946. Renamed L'Alsacien, she was commissioned into French service on 4 February 1946. After a refit, she served as a destroyer escort and training vessel, based mainly in Brest. She was eventually deemed obsolete and was struck from the French Navy List on 8 March 1954. The ship was subsequently sold for scrap and broken up in Brest in 1955.
