The submarine class UE consisted of the mines suitable for use in the deep sea - submarine types UE I and UE II of the German Imperial Navy .

Type UE I

The type UE I was the first German submarine type with dry storage for mines.

history

Since the existing UC I mine submarine was only designed for use near the coast, the development of a new UE mine submarine was initiated as early as the end of 1914 . This should have a much greater range, weigh 600 to 700 t and carry 34 mines inside the boat, dry and accessible to the crew. With this type, too, great importance was attached to the shortest possible construction time. Therefore we used quickly procurable but the boat weight too weak 450 hp - diesel engines , as the generator drive for the unfinished battleships originally SMS Sachsen and SMS Württemberg the Bayern class were provided. In addition, a single-shell design was sought. The first four boats were ordered on January 6, 1915 from AG Vulkan Hamburg ( U 71 and U 72 ) and on January 9, 1915 from the Kaiserliche Werft Danzig ( U 73 and U 74 ). They were single-hulled boats with saddle tanks (comparable to those of Type VII from World War II ) and a displacement of approx. 800 t. In the stern of the boats there were two discharge pipes for mines. These ended in a large storage room for the mines. This moved the engine room into the middle of the boat. In front of this was the headquarters under the tower. The front third as were the crew accommodation and including the batteries room . Due to the weak diesel engines, the boats were very slow and turned out to be top-heavy. This led to frequent undercutting of the water surface in rough seas. In the jargon, the crews called the boats of the class, jokingly, roughly derogatory, grief children . They were armed with a bow torpedo tube on the port side (left) and a stern torpedo tube on the starboard side (right). Both pipes were outside the pressure hull and could therefore only be serviced and loaded when the boat was surfaced. They were only used for self-defense. For the surface combat there was a 8.8 cm cannon behind the tower on the quarterdeck. Later the boats were partially equipped with stronger 10.5 cm cannons. They could carry 34 mines and a total of four 50 cm torpedoes. On February 27, 1915, six more boats of this type were ordered from the Vulkan shipyard in Hamburg ( U 75 to U 80 ).

Type UE II

The U-Boot-Klasse UE II was a type of mine submarine of the Imperial German Navy. It is often referred to as a large mine submarine instead of Type UE II.

history

In the spring of 1916, the submarine inspection of the Reichsmarinamt initiated a number of new submarine developments, including the type UE II. There were two main reasons for this. The proven Type UC II was considered too small to reach and mine capacity for many tasks and the type UE I had major shortcomings in terms of seaworthiness and speed. It also proved to be very prone to failure. The construction of the two-hulled boat was mainly based on the fleet submarines Ms-Type U 115 - U 116 . Here almost the entire foredeck was taken over unchanged. In the stern, the pressure hull had to be designed elliptically to accommodate the large mine storage room. Here, too, as with type UE I, the mines were ejected from the storage room through two ejection tubes to the rear. Either 30 additional mines or 10 torpedoes could be carried in pressure-resistant storage boxes on the deck. In addition, the boats were armed with four bow torpedo tubes and a 15.0 cm cannon (with the exception of SM U 123 , which instead received two 10.5 cm UToF ). Ten units were ordered on May 27, 1916: U 117 to U 121 from AG Vulkan Hamburg , U 122 to U 126 from Blohm & Voss .
