Panzer IV - Production

Production

The Panzer IV was originally intended to be used only on a limited scale, so initially Krupp was its sole manufacturer. Prior to the Polish campaign, only 262 Panzer IVs were produced: 35 Ausf. A; 42 Ausf. B; 140 Ausf. C; and 45 Ausf. D. After the invasion of Poland, and with the decision to adopt the tank as the mainstay of Germany's armored divisions, production was extended to the Nibelungenwerke factory (managed by Steyr-Daimler-Puch) in the Austrian city of St. Valentin. Production increased as the Ausf. E was introduced, with 223 tanks delivered to the German army. By 1941, 462 Panzer IV Ausf. Fs had been assembled, and the up-gunned Ausf. F2 was entering production. The yearly production total had more than quadrupled since the start of the war.

As the later Panzer IV models emerged, a third factory, Vomag (located in the city of Plauen), began assembly. In 1941 an average of 39 tanks per month were built, and this rose to 83 in 1942, 252 in 1943, and 300 in 1944. However, in December 1943, Krupp's factory was diverted to manufacture the Sturmgeschütz IV, and in the spring of 1944 the Vomag factory began production of the Jagdpanzer IV, leaving the Nibelungenwerke as the only plant still assembling the Panzer IV. With the slow collapse of German industry under pressure from Allied air and ground offensives — in October 1944 the Nibelungenwerke factory was severely damaged during a bombing raid — by March and April 1945 production had fallen to pre-1942 levels, with only around 55 tanks per month coming off the assembly lines.
