Armament

The German torpedo boat T1 was the lead ship of her class of a dozen torpedo boats built for the Kriegsmarine (German Navy) during the late 1930s. Completed in late 1939, she was assigned to escort minelayers as they laid their minefields in the English Channel in September 1940. The boat participated in an abortive attempt to attack several convoys off the Scottish coast two months later. T1 ran aground in January 1941 and was under repair until July. The following month she was placed in reserve and was reactivated in June 1942 for duty with the Torpedo School. In April 1944 the boat returned to active duty and was assigned to the Baltic Sea area. She escorted a bombardment mission in January 1945 and was sunk during an air raid on 9 April while refitting.

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 600-long-ton (610 t) displacement limit of the London Naval Treaty because such small ships did not count against the national tonnage limit. [1] The boats had an overall length of 84.3 meters (276 ft 7 in) and were 82.2 meters (269 ft 8 in) long at the waterline. After the bow was rebuilt in 1941 to improve seaworthiness, the overall length increased to 87.1 meters (285 ft 9 in). [2] The ships had a beam of 8.62 meters (28 ft 3 in), and a mean draft of 2.83 meters (9 ft 3 in) at deep load and displaced 859 metric tons (845 long tons ) at standard load and 1,108 metric tons (1,091 long tons) at deep load. [3] Their crew numbered 119 officers and sailors. [4] Their pair of geared steam turbine sets, each driving one propeller, were designed to produce 31,000 shaft horsepower (23,000  kW ) using steam from four high-pressure water-tube boilers [2] which would propel the boats at 35 knots (65  km/h ; 40  mph ). They carried enough fuel oil to give them a range of 1,200 nautical miles (2,200 km; 1,400 mi) at 19 knots (35 km/h; 22 mph). [3]

As built, the Type 35 class mounted a single 10.5 cm (4.1 in) SK C/32 gun on the stern. Anti-aircraft defense was provided by a single 3.7 cm (1.5 in) SK C/30 anti-aircraft gun superfiring over the 10.5 cm gun and a pair of 2 cm (0.8 in) C/30 guns on the bridge wings. They carried six above-water 533 mm (21 in) 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. [5]

As late as April 1944, T1 had neither received radar nor had her anti-aircraft suite augmented. In mid-July the boat exchanged her rear torpedo mount for a 3.7 cm AA gun. No further information is available on any other modifications she might have received before her loss in 1945. [6]

Construction and career

T1 was ordered on 16 November 1935 from Schichau, laid down at their Elbing, East Prussia, shipyard on 14 November 1936 [7] as yard number 1380, [2] launched on 17 February 1938 and commissioned on 1 December 1939. Plagued with mechanical problems, the boat was working up until September 1940. [7] T1 escorted a minelaying mission in the English Channel on 6–7 September as part of the 1st Torpedo Boat Flotilla with her sister ships T2, T3, and the torpedo boat Kondor. Five days later, T1, the torpedo boat Seeadler, T2 and T3 were ordered to proceed to France. They were attacked enroute by a British light bomber that damaged T2 and forced her to return to Germany for repairs. T1's stay in France was brief and she was ordered to return home a few days later. By November the 1st and 2nd Torpedo Boat Flotillas had transferred to Stavanger, Norway. German aerial reconnaissance had located two coastal convoys in early November that the Kriegsmarine estimated would pass Kinnaird Head, Scotland, during the early morning of 7 November. Both flotillas, consisting of T1 and her sisters, T4, T6, T7, T8, T9 and T10, sailed on 6 November in an attempt to pass through a gap in the British minefields and intercept the convoys around 02:00 the following morning. The British had extended their minefields further north unbeknownst to the Germans and T6 struck a mine shortly after midnight and sank. T7 and T8 rescued the survivors and the operation was abandoned. T1 formed part of the escort for the commerce raider Kormoran through Norwegian waters in early December. [8]

T1 ran aground off Kristiansand on 22 January 1941 and temporary repairs were made at the shipyard in Horten; the ship was ordered to proceed for permanent repairs at Warnemünde once one engine could be operated, but the repairs were actually made in Gotenhafen and lasted until July. She was reduced to reserve on 15 August [9] that lasted through June 1942. That month, she was recommissioned and assigned to the Torpedo School. In November 1943 the boat began a long refit that lasted through March 1944. [2] [7] In April 1944, the four oldest of the sisters, including T1, were assigned to a training unit as they lacked radar and a reinforced anti-aircraft armament. This arrangement did not last long as the German situation in the east deteriorated and they began convoy escort duties throughout the Baltic a few months later. As of 14 August the 2nd Torpedo Boat Flotilla consisted of nine Type 35s, including T1. She was damaged by an attack by Soviet aircraft while docked in Libau, Latvia, on 9 October. [10] The ship escorted the heavy cruiser Prinz Eugen as the latter ship supported a German counterattack against advancing Soviet forces near Cranz, East Prussia, on 29–30 January 1945. T1 was refitting in Kiel as of March [11] and sank after being hit by two or three bombs during a Royal Air Force attack on Kiel on the night of 9 April with the loss of nine crewmen. Her wreck was demolished on 20 May 1946. [2] [7] [12]

Type 35 torpedo boat

The Type 35 torpedo boat was a class of a dozen torpedo boats built for Nazi Germany's Kriegsmarine in the late 1930s. Although the first boats were completed a few months after the start of World War II in September 1939, none of them were able to participate in the Norwegian Campaign of April–June 1940. They began escorting convoys and minelayers as they laid their minefields in the North Sea and English Channel in July. Most of the boats were transferred to Norway in November where they made an unsuccessful attempt to attack shipping along the Scottish coast that saw one boat sunk.

German destroyer <i>Z28</i> Warship

Z28 was one of fifteen Type 1936A destroyers built for the Kriegsmarine during World War II. Built as a flotilla leader with fewer guns than her sister ships, she was completed in 1941. The ship spent most of the first few years of her service in Norwegian waters, escorting convoys and laying minefields. Z28 ran aground in early 1943 and spent the rest of the year under repair. The ship briefly returned to Norway at the beginning of 1944, but was transferred to the Baltic shortly afterwards to support minelaying operations in the Gulf of Finland. That was her primary focus through July and then she began escorting German cruisers as they bombarded Soviet troops ashore in addition to German convoys evacuating people from Finland and the Baltic States.

Type 23 torpedo boat Ship class

The Type 23 torpedo boat was a group of six torpedo boats built for the Reichsmarine during the 1920s. As part of the renamed Kriegsmarine, the boats made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, they played a minor role in the Norwegian Campaign of 1940, Albatros being lost when she ran aground. The Type 23s spent the next several months escorting minelayers as they laid minefields and escorting ships before the ships were transferred to France around September. Möwe was torpedoed during this time and did not return to service until 1942. They started laying minefields themselves in September and continued to do so for the rest of the war.

German torpedo boat <i>Kondor</i>

Kondor was the fifth of six Type 23 torpedo boats built for the German Navy. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she played a minor role in the attack on Oslo, the capital of Norway, during the Norwegian Campaign of 1940. Kondor spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September. She started laying minefields herself that month and continued to do so for the rest of the war. The boat returned to France in 1942 and helped to escort blockade runners, commerce raiders and submarines through the English Channel and the Bay of Biscay. Damaged by a mine shortly before the Allied Invasion of Normandy in June 1944, Kondor was under repair on the day of the landings. Recognizing that she could not be repaired quickly, the boat was decommissioned later that month and was then further damaged by British bombers so that she was declared a constructive total loss.

German torpedo boat <i>Falke</i>

Falke was the sixth and last Type 23 torpedo boat built for the German Navy. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she played a minor role in the Norwegian Campaign of 1940. Falke spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September. She started laying minefields herself that month and continued to do so for the rest of the war. After a refit in early 1941, the boat was transferred to the Skaggerak where she was assigned escort duties. Falke returned to France in 1942 and was one of the escorts for the capital ships sailing from France to Germany through the English Channel in the Channel Dash. She helped to escort blockade runners, commerce raiders and submarines through the Channel and the Bay of Biscay for the next several years. The boat attacked Allied ships during the Invasion of Normandy in June 1944, but was sunk by British bombers that same month.

German torpedo boat <i>Jaguar</i>

Jaguar was the sixth and last Type 24 torpedo boat built for the German Navy during the 1920s. The boat made multiple non-intervention patrols during the Spanish Civil War in the late 1930s. During World War II, she played a minor role in the Norwegian Campaign of 1940. Jaguar spent the next several months escorting minelayers as they laid minefields and damaged heavy ships back to Germany before she was transferred to France around September. She started laying minefields herself that month and continued to do so for the rest of the war. After a refit in early 1941, the boat was transferred to the Skaggerak where she was assigned escort duties. Jaguar returned to France in 1942 and was one of the escorts for the capital ships sailing from France to Germany through the English Channel in the Channel Dash. She helped to escort blockade runners, commerce raiders and submarines through the Channel and the Bay of Biscay, as well as Norwegian waters, for the next several years. The boat attacked Allied ships during the Invasion of Normandy in June 1944, but was sunk by British bombers that same month.

German torpedo boat <i>T2</i> German torpedo boat of the Type 35 class (1935–1946)

The German torpedo boat T2 was one of a dozen Type 35 torpedo boats built for the Kriegsmarine during the late 1930s. Completed in 1939, she was not combat ready until mid-1940, when she spent several months escorting minelayers as they laid minefields. The boat returned to Germany after being damaged and supported operations in the Baltic Sea after the start of Operation Barbarossa in June 1941. T2 returned to France at the end of the year, escorting a commerce raider through the English Channel. She then escorted a pair of battleships and a heavy cruiser through the Channel back to Germany in early 1942 in the Channel Dash. The boat was placed in reserve upon her return and was transferred back to France in 1943, where she helped to escort blockade runners through the Bay of Biscay. In mid-1943, she returned to the Baltic and briefly served as flagship of a submarine flotilla before being assigned to the Torpedo School. T2 was sunk in an air raid in July 1944, but was refloated several months later. She was never repaired and eventually scrapped in 1946.

German torpedo boat <i>T3</i>

The German torpedo boat T3 was one of a dozen Type 35 torpedo boats built for the Kriegsmarine during the late 1930s. Completed in 1940, she was assigned to escort minelayers as they laid their minefields in the North Sea and English Channel in July. The boat was sunk in France by British bombers in September and was refloated the following year. T3 was assigned to the Torpedo School when her repairs were completed in 1943. She returned to active duty a year later and escorted German ships as they bombarded Soviet positions. The boat sank a Soviet submarine in early 1944 and she struck a mine in March 1945 and sank with heavy loss of life.

German torpedo boat <i>T4</i>

The German torpedo boat T4 was one of a dozen Type 35 torpedo boats built for the Kriegsmarine during the late 1930s.
