STEN and its copies in service with Germany
The British STEN submachine gun was distinguished by its extreme simplicity of design and low cost of production. Thanks to this, the release of such weapons managed to establish not only in Great Britain, but also in other countries. Moreover, in 1944, even Hitler's Germany began to produce its own versions of the submachine gun. However, such an attempt to save money did not affect the general course of the war.
Trophy in service
In 1941, British factories mastered the production of the first model STEN submachine gun, and a few months later a modernized version appeared. In the shortest possible time, it was possible to re-equip its own army and begin preparations for new operations. Already in August, an unsuccessful raid on Dieppe took place, during which the British suffered heavy losses. As a result of this battle, the German military were able to first get acquainted with a number of enemy developments, incl. with a new simplified submachine gun.
From a certain time, Great Britain began to support the Resistance units in the occupied countries. Various cargoes were delivered to them by air, incl. armament. The cheap, simple and compact STEN, capable of using captured German cartridges, turned out to be a convenient novelty for the partisans.
However, not all "parcels" got to the Resistance. So, a significant part of the cargo for the French partisans was discovered by the Germans. The captured weapons were sent for storage to the Paris office of the RSHA. From there, trophies were shipped to various rear and police units, for which there were not enough German products. The STEN Mk I entered service under the designation MP-748(e) and the Mk II product received the designation MP-749(e).
Initially, German experts were skeptical about the British submachine gun, since the overly simplified design showed low performance. However, in the face of a lack of own weapons, we had to close our eyes to the shortcomings of trophies, and they became a real alternative to the scarce MP-38/40.
Product "Potsdam"
In the summer of 1944, after the Allied landings in Normandy and further advance deep into France, the number of captured weapons sharply decreased - in contrast to the needs of the German structures. Therefore, at the beginning of autumn, it was decided to launch its own production of a copy of the STEN Mk II product. Such a copy was named Gerät Potsdam ("Product" Potsdam ").
In September 1944 Mauser received a special order. She was supposed to copy a captured submachine gun and set up its production. In addition, it was required to develop two sets of technical documentation with different features. The first was intended to be transferred to large weapons factories with developed production capacities, and the second was planned to be distributed among small factories with limited capabilities.
The Potsdam submachine gun was an exact copy of the British STEN Mk II with minimal technological differences. This allowed us to get the desired features, although it led to some problems. First of all, Potsdam has retained all the shortcomings of its prototype. In addition, the copied weapon, despite the unification of the cartridge, could not use the standard German magazines from the MP-38/40. Cost was another issue. One submachine gun cost 1800 Reichmarks. For comparison, the StG-44 assault rifles in the series by that time cost less than 100 marks.
Some sources mention that all the smallest details were copied, right down to the marking. From this it is concluded that there are plans to use Gerät Potsdam in sabotage under false flag, etc. However, reliably known German-made submachine guns do not have the characteristic British brands. In addition, the only goal of the project was to produce the cheapest and simplest weapon possible.
The documentation was ready in mid-October, and immediately after that, an order for 10 thousand items appeared. By the end of November, 5300 submachine guns had been manufactured at the Mauser, and another 5100 units were produced in December. The ordered 10 thousand were shipped to the armies, and the fate of the remaining 400 Potsdam is still unknown. At the same time, the Hänel plant launched production of stores and by the end of the year produced almost 17 thousand units. Another 22,5 thousand stores were released in the first months of 1945.
Neumünster instead of Potsdam
On November 2, 1944, when production of Potsdam was just starting, Mauser received a new order. Now she had to rework the existing design towards further simplification and cost reduction. Upon the readiness of the project, he had to replace the predecessor in production. As before, it was planned to establish production at developed factories and small workshops.
In the documents, the new project was designated as Gerät Neumünster. Later, the incorrect designation MP-3008 became widespread. This index comes from the order number of November 2, which asked the development of weapons - "1-3-3008". Officially, this designation was never used.
In order to simplify the design, the barrel mount was redone. On STEN Mk II, it was secured in the receiver with a nut. The Neumünster used a bushing with pins instead. The receiver was extended for a new spring. The swivel magazine receiver, which also served as a protection for the ejection window, was made immovable and converted into a magazine from the MP-38/40. Its neck was now under the receiver, and the ejection window remained on the right. In connection with the transfer of the store, the shutter had to be redone. Trigger, controls, butt, etc. left unchanged.
The development and refinement of the Neumünster took only a few weeks. By the end of November, the submachine gun was ready for release at any German enterprise. Already on November 15, the first order appeared. The army wanted to get 1 million units. weapons with delivery before March, 250 thousand per month. At the end of November, an additional order for 50 thousand items for the newly created Volkssturm appeared.
However, the implementation of these orders encountered difficulties. The continued production of Potsdams, the shortage of materials and the general difficulties of that period led to the fact that the mass production of Gerät Neumünster on the Mauser could not be launched until the beginning of 1945. Up to 30 other organizations were involved in production, but they also did not succeed. In addition, various problems appeared during the tests, and the army began to plan the development of another model, devoid of the disadvantages of the Neumünster.
In limited quantities
By the beginning of 1945, customers revised their plans for the supply of Neumünster. Starting in January, the monthly production of submachine guns was assigned to only 10 thousand units. In the spring it was planned to double it, and in the summer to reach rates of up to 250 thousand per month and by the fall to release the desired 1 million items.
In the winter of 1944-45, the army had to deal with the issue of ammunition production. So that each of the million ordered submachine guns could have three equipped stores, 96 million rounds of ammunition were required. In this regard, in December there was a requirement to increase the production of 9x19 mm Luger cartridges by 150 million pieces. per month. As in the case of weapons, these requirements could not be met.
It is not known how many enterprises managed to establish the production of Neumünster submachine guns. The general release of such weapons also remains uncertain. According to various estimates, from December 1944 to April 1945, it was possible to collect from several hundred to 45-50 thousand units. Apparently, the actual number of weapons is closer to the minimum estimates. So, among the known copies, the largest serial number was found for a product from the Blohm & Voss plant - "232". It is unlikely that other enterprises were able to reach the four- and five-digit numbers.
Production was carried out at several enterprises with their own technological features. Known samples from different factories differ markedly from each other. So, some submachine guns received a receiver from a pipe, while others used a curved and welded sheet. The contours of the units and fittings were seriously different. For example, the aforementioned submachine gun "232" from Blohm & Voss had a full-fledged wooden handle instead of a protrusion on the butt. Samples with a wooden butt are also known.
Objectives and Outcomes
In 1944, Hitlerite Germany faced the problem of a shortage of small arms and began looking for alternatives to the models available in the series. One of the solutions to this problem was the copying of the most simple design of a foreign model. However, this did not allow meeting all the customer's requirements - Gerät Potsdam and Gerät Neumünster could not be produced in large quantities, and their cost was unacceptably high.
The reasons for this are quite simple. The STEN submachine gun was created by the British industry, taking into account the available resources and production capabilities. By optimizing the design and manufacturing techniques, it was possible to reduce the costs of materials, labor and money to a minimum. Germany, copying STEN, was forced to start production from scratch and could not use the backlog on its own samples.
All this led to obvious difficulties, the struggle with which required a lot of effort, time and money. Moreover, all these problems arose in the most difficult period for Germany, when its defeat was already a matter of time - and any unjustified spending worsened the situation. It should be recalled that in 1944-45. other models of simplified and cheaper weapons were also developed, none of which helped to avoid defeat.
The program of copying a captured submachine gun ended in a real failure. With unacceptably high costs, no more than 10-15 thousand units were manufactured in a few months. weapons that could no longer influence the course of the war. Meanwhile, the UK and other countries were releasing tens of thousands of STEN submachine guns every month, supplying the army with weapons and avoiding unnecessary spending.
