Type 1945 destroyer

The Type 1945 destroyers were a planned class of destroyers, for the Kriegsmarine, whose design was based upon that of the Type 1936D and E destroyers. Their plan involved a return to steam boilers, which had been replaced by diesel engines in all ships designs after the Type 1942 destroyers. No ships were ever built, as the end of the war was rapidly approaching.

Development
The Type 1945 destroyer was designed in 1945, based upon the design of the Type 1936D and E destroyers, the plans for which were later accidentally destroyed by fire. They were designed during a time when Germany was prioritizing construction of submarines, with little to no effort going into her surface fleet, making the odds of the Type 1945 destroyers, or any other type of ship which was designed after 1942, being constructed, near zero. However, the Konstruktionsamt (Construction Department) continued to create designs for surface ships until the end of the war.

Before the design was even created, Germany was restricting the use of her surface fleet; after the sinking of the German battleship Bismarck on 27 May 1941, heavy restrictions were placed upon surface ship commanders' tactical freedom. Around the time the design was created, after the sinking of the German battleship Tirpitz on 12 November 1944, most of Germany's surface ships were being pulled back entirely, to serve only in the Baltic Sea. From the spring of 1945 to near the end of the war, the Kriegsmarine was almost entirely focused upon resupplying and supporting garrisons along the Baltic Coast. Later on, in May, the Kriegsmarine embarked upon the task of evacuating hundreds of thousands of civilians and soldiers from the east, ahead of the Soviet forces which were rapidly pushing westward.

The Type 1945 destroyers were designed to be able to defend against submarines, light naval forces, and aircraft, particularly torpedo bombers. Their design differed greatly from previous ones in that it utilized steam turbines, rather than diesel engines. Overall, their design gave them 12% higher engine performance despite having lighter machinery, and a more powerful main armament with a shorter hull. The project never made it past the drawing board, and no ship of the class was ever ordered or laid down.

Characteristics
The ships of the Type 1945 destroyer class were to be 120 m long at the waterline and 125.5 m long o/a, have a beam of 12 m, a draught of 3.88 m, and displace 2700 t at standard load, 3,100 t at full load, and 3,700 t at deep load. They were to have a complement of 350, and carry two motor pinnaces, one torpedo cutter and a motor dinghy.

They were to be armed with eight 12.7 cm SK C/41 guns, placed in four twin turrets, with 1,440 rounds of ammunition, four 5.5 cm L/76.5 guns, with 5,000 rounds of ammunition, twelve 3 cm L/66.6 M-44 guns, with 24,000 rounds of ammunition, eight total 53.3 cm torpedo tubes, placed in quadruple tubes on her deck, with 16 torpedoes, and 100 mines. They were to have high-angle (anti-aircraft) director ship gun fire-control systems, placed on their fore and aft, which were to be fitted with radio direction finders.

They were to be propelled by two three-bladed propellers, two sets of Wagner turbines, four Wagner-Deschimag boilers feeding high-pressure superheated steam (at 70 atm and 400 C), intended to give her 80,000 shp, and a speed of 42.5 kn, 39.5 kn, or 37 kn, depending on if they were at standard load, full load, or deep load, respectively. They were to carry 800 t of oil, to give her a range of 3,600 nmi at 19 kn. The machinery was calculated to have a weight-power ratio of 12 kg/shp.
