history
Development history
The fleet torpedo boat in 1944 was an office design which consists of the design of the fleet torpedo boat 1941 A was derived. The project was created in two variants of the fleet torpedo boat 1944 A and B , which differed only slightly. In the drafts for the fleet torpedo boat in 1944 , the typical German smooth-deck construction was deviated from, in order to achieve better seaworthiness and lower top-heaviness , the stern in the rear part of the hull was lower by one deck. So the aft turret could be built lower. The freeboard height was around 1.5 m higher than that of the torpedo boat in 1937 .

construction
On March 28, 1944, the F. Schichau shipyard in Elbing, West Prussia, was given orders to build nine boats. As is usual for smaller units in the Kriegsmarine, the boats were not given any names, only the IDs T 52 to T 60 . There, some building preparations were made, but without laying a boat on the keel and soon afterwards the building contracts were canceled again.

hull
The hull of a fleet torpedo boat in 1944 , divided into 12 watertight compartments and completely welded, would have had an overall length of 103 m, a maximum width of 10.1 m and a maximum draft of 3.7 m. The planned standard displacement should amount to 1,418 ts and the deployment displacement to 1,794 ts. It would have been made of shipbuilding steel ST 52 in transverse rib longitudinal band construction, with a double floor which would have taken up 70% of the total length .
drive
The design included two Wagner turbines with gear drives - in two separate turbine rooms - and four Wagner superheated steam boilers, with natural water circulation and oil-fired. It was planned to install an Illies system (named after the designer Dr. Ing.Kurt Illies), which was constructed in the Schichau shipyard. This IS system (Illies-Schichau system) should make it possible to reduce the operating pressure at a speed of 25 knots to 19 atü (19.6133 bar ) with correspondingly lower steam temperatures and thus fuel savings . In addition, the ancillary units previously operated with steam, such as pumps, etc. Ä. Driven with three-phase current to save their not inconsiderable steam consumption and to make the main drive system available. The design and installation of the boilers and turbine systems in a power plant arrangement was planned as on the fleet torpedo boats in 1939 and 1941 .
The approximate power of this propulsion system would have been 52,000 hp , which would have allowed a speed of 37 knots .
crew
A crew of 8 officers and 214 NCOs / crews (224 men) was planned.
Armament
artillery
As primary armament were four 10.5-cm-TK M44 with caliber length 47 in two double carriages M 44 are provided. This newly developed multi-purpose gun was to be placed on the boat center line, one in front of the bridge and one aft behind the superstructure. In order to standardize the light anti-aircraft armament - replacing the 2 cm Flak 38 and 3.7 cm SK C / 30 guns of the previous classes - ten 3 cm Flak M44 with caliber length 44 should be set up in five double M / 44 mounts. One carriage in front of the bridge, two in front of and one behind the last chimney and one at the end of the deckhouse.
Torpedoes
The planned torpedo armament would have consisted of two triple torpedo tube sets with a caliber of 53.3 cm that could be pivoted through 360 ° . These would have been in the center line of the boat, one set behind the front and one aft chimney, and fired type G7a torpedoes . The transport of reserve torpedoes in containers on the upper deck was not intended.
Others
The planned armament also included four depth charge launchers , six depth charge single bearings and rails on the aft deck for laying sea mines .
Fire control system
The fire control system should consist of the Flak control device M / 44 , which would have been installed in a rotating dome on the bridge structure. This flak control device, which is currently in development, was intended to combine optical distance measurement and radio measurement ( radar ) and replaced the 3 m basic distance measurement device 3u which had been installed on the previous classes .
Dinghies
As dinghies one had motor dinghy , a cutter and a dinghy provided.
