Nibelungenwerk

The Nibelungenwerk was built in four stages.

• The first stage was mostly focused on construction with a start-up workshop set up at Steyr-Daimler-Puch's main factory in Steyr for tank spare parts in mid-1940.[1]
• The second stage included supply contracts for parts production were awarded beginning on 23 December 1940, including the production of 5,400 wheels for the Krupp-Gruson-Werke in Magdeburg-Buckau.
• In 1942, with the completion of the third stage of expansion, series production of the Panzer IV began, along with assembly of the Tiger I.
• With the last expansion stage in 1943, production capacity was increased.

Eventually, the factory consisted of a total of nine halls. Seven halls were 120 meters long and 60 meters wide and made of reinforced concrete. The other two halls were of steel construction and were 120 meters long and 120 meters wide. In order to maintain production even after bombing raids, the factory was supplied with electricity, compressed air, heat and water through an underground system. The factory was also connected to two railway lines, with each hall having its own siding.

In the late autumn of 1941, the workforce stood at 4,800 people, mainly from Austria and Germany. During the course of the war, many Austrian and German workers were conscripted and replaced by foreign prisoners of war. In numerical order these were French, Italians, Greeks, Yugoslavs, Russians and, finally, 600 concentration camp inmates. The number of workers at the end of 1944 amounted to about 8,500 people. Due to the growing shortage of skilled workers and the time-consuming training and instruction of foreign workers, relatively large-scale concessions were made to the increasingly important foreign workers. Thus, in addition to the toleration of a brothel in the camp settlement, the skilled workers were allowed holidays, which after the successful Allied invasion of Normandy had the consequence that many Frenchmen did not return. In August 1944, an external camp of the Mauthausen-Gusen concentration camp complex was built on the site, in which 1,500 prisoners were accommodated and used for forced labour.

Of the total of 8,500 Panzer IVs produced, nearly 4,800 were produced in the Nibelungenwerk.

After completion of the four expansion stages, the plant was the largest tank factory under Axis control. In addition to the Panzer IV, 576 self-propelled guns (Sturmgeschütz IV and Jagdpanzer IV) were produced and the factory also converted the Porsche version of the Tiger I to the Elefant.

The Nibelungenwerk was the only German tank factory which had a well-structured assembly line, with main and secondary lines. The production lines consisted of simple load-carriers, which were coupled with rods and moved forward with a cable. The production station times varied between four minutes, for the wheel suspension, to several hours, for the final assembly. As only a third of the required individual parts were manufactured in-house, the production line was dependent on undisturbed supply logistics, and on October 17, 1944, the plant was badly damaged in an air raid. As a result, almost all the production had to be outsourced.

Nevertheless, of 3,125 Panzer IVs produced in 1944, 2,845 were produced in the Nibelungenwerk. At the end of 1944 production of the Jagdtiger began. The conversion of the production took place without any problems, since the cranes and other technical equipment were over-specified. In the last days of the war, 65 Panther tanks and Tigers were repaired.

On May 8, 1945, American troops of Major General Stanley Eric Reinhart's 259th Infantry Regiment occupied the city liberating the Nibelungenwerk's French and Soviet prisoners of war and Czech forced labourers.

After the Red Army occupied the factory on May 9, 1945, production continued on a small scale, so that some Panzer IVs could be made available for the victory parade in Moscow.
