The 1941 fleet torpedo boat was a class of no longer fully built torpedo boats of the German Navy during World War II . The construction of 14 boats began in 1943 and 1944 in the Schichau shipyard in Elbing . Due to the lack of workers and materials caused by the war, none was completed before all work was stopped on January 22, 1945. Some of the boats were towed west in the face of the advancing Soviet troops.
concept
The type was a slightly enlarged modification of the 1939 fleet torpedo boats . Above all, the experience gained with the 1939 type in use had shown that its machine systems were undersized for boats of this size; the drive power has been increased accordingly.
As a further development of the fleet torpedo boats , the draft of a fleet torpedo boat 1941A was worked out. Another revised draft of the fleet torpedo boat in 1944 was commissioned from the Schichau shipyard in 1944.
construction
The first boat, the T 37 , was launched on April 29, 1944 and by January 1945 it was over 96% complete, in particular all boilers and turbines had already been installed. The sister boats T 38 to T-40, which were also launched in 1944, were up to 84% finished and when all work on the new torpedo boats was stopped at the Schichau shipyard, they could be towed west. From January 25 to 26, 1945, the T 37 , T 38 and T 39 were brought from Elbing to Danzig in the Schichau shipyard there. For T 37 and T 38 was under KTB of the destroyer leader on 28 January, the ongoing construction at Deschimag in Bremen provided.
- T 37 was included in the emergency program ordered by the OKM in March 1945 and brought from Danzig via Kiel and the Kiel Canal to Brake an der Unterweser , where it became US war booty on May 8, 1945. It is said to have been sunk in the Skagerrak on July 26, 1946 .
- T 38 should no longer be completed because a gearbox was not yet installed. Like T 39, it arrived in Kiel in mid-March 1945 . Both boats were taken over by the Royal Navy on May 8, 1945 and are said to have been sunk in the Skagerrak on May 10, 1945.
- T 40 aground on March 10 during the transfer in Gdansk Brösen and was there on March 23, 1945 depth charges exploded.
1944 or T 41 to T 45 to set keel ; During the conquest of Elbing they were in various stages of construction.
- The launch of the T 41 took place on September 12, 1944. In January 1945 the boat was 66% complete and could be towed to Danzig on January 26, 1945. It was likely scrapped after 1945.
- T 42 was launched on October 10, 1944 and was around 58% complete in January 1945; the unfinished boat was probably blown up in Elbing in March 1945.
- T 43 to T 45 were laid down in 1944 with hull numbers 1636 to 1638 (May 23, June 29 and August 7); all three were blown up when Elbing was evacuated in March 1945.
The construction contract for T 46 to T 48 was issued on June 16, 1943, and they were given construction numbers 1639 to 1641. The boats, which were only 20 to 25% complete, are said to have been blown up by February 13, 1945 at the latest when the shipyard was cleared.
T 49 to T 51 were commissioned on January 11, 1944, and the construction numbers 1717 to 1719. T 49 and T 50 were still laid on the keel, but remained in the shell construction stage; the hulls were also blown up by February 13, 1945. Construction of the T 51 never started.

technical description
hull
The design corresponded to that of the fleet torpedo boats in 1939. The hull was built in transverse rib and longitudinal band construction and was completely welded. The hull had an overall length of 106 m, in the construction waterline of 102 m. The maximum width was 10.7 m. The construction displacement was 1782 t, the type displacement was 1493 ts , the operational displacement was 2155 t.
drive
Like their predecessors, the boats were to be powered by a superheated steam turbine system. The four oil-fired Wagner superheated steam boilers and the two Wagner geared turbines were each set up in two separate boiler and turbine rooms. This corresponded to the power plant arrangement of the type 1939. The planned output was 40,000 WPS for the two screws with three blades each. The two spade oars stood in the stream of propellers. The maximum speed according to the construction should be 34 kn . A maximum of 582 t of heating oil should be carried. The driving range according to the design should be at 2800 nm at 19 kn.
crew
The crew should be 197 men.
Armament and weapons control system
The planned armament and its arrangement basically corresponded to that of the 1939 type. The main artillery armament was four 10.5 cm SK C / 32 na L / 45 cannons. One gun was in front of the bridge, one between the superstructures, the last two aft behind the superstructures, one of which was raised on a low superstructure on the boat center line. The single mounts were of the 10.5 cm MPL C / 32 ge type . With a maximum elevation angle of + 80 °, as an all-purpose weapon, it could fight sea, land and high-flying air targets. A total of 2400 rounds of ammunition were carried for the guns.
First of all, optical 3 m basic distance measuring devices of the type 3u , set up on the bridge structure, were to be used on T 37 to T 42, as with the predecessor type . After revising the construction plans, a basic device with an artillery control radio measuring device in a rotatable dome was designed for the T 40 to T 50 .
At the time of commissioning, the anti-aircraft armament for boats up to T 39 were six 3.7 cm anti-aircraft guns of the SK C / 30 L / 83 type in three three-axis stabilized double C / 30 mounts with 12,000 rounds of ammunition and eight 2 cm MWC anti-aircraft guns / 38 L / 65 in single mounts C / 44. From T 40 , the flak armament was to be reinforced as follows: six 3.7 cm flak of the type M 42 L / 69 in three double mounts M 42 and twelve 2 cm flak MWC / 38 L / 65 in three four-pack mounts C / 38 with protective shields.
Two swiveling 53.3 cm triple torpedo tube sets were also planned as armament. The armament with depth charges and up to 50 mines should correspond to that of the fleet torpedo boats in 1939.
