Sturmgeschutz IV PSC Conversion

PSC StuG III Superstructure and PzIV hull

PSC StuG III Superstructure and Pz IV hull

 

The success of the Sturmgeschutz III led to a demand for more hulls than could be produced from Alkett, the existing manufacturer of the Pz III chassis. The G variant was by far the commonest, in excess of 8,000 being produced from December 1942 until the end of the war.¹

Krupp were called in, as manufacturers of the Pz IV chassis, and the simple expedient of adding the StuG III superstructure to the Pz IV was adopted. An extended box was necessary to accomodate the drivers position on the PzIV hull, but little else needed to be done. Production only started in November 1943, when the Alkett factory suffered severe bomb damage.

The StuG IV did not suffer from the nose heaviness of the Jagdpanzer IV, an ostensibly better design on paper that earned the nickname of “Guderian’s Duck”² from its habit of nosediving into anything soft or wet. Roughly equal numbers were produced of each design: 1,141 StuG IVs compared to 1,208 Jagdpanzer IVs.

My conversion was a simple cut-and-shunt of a PSC StuG III top onto a Pz IV hull. The driver’s box came from scrap plastic and card. Nothing much to it really.

With the old 2-part PSC tracks, the method of assembly that works for me is to stick the top half of the track to the idler assembly, then stick it to the tank hull. Once everything is dry, the bottom half goes on fairly easily. Finally the front and back wheels go on.

Full marks to PSC for doing a StuG III rather than a JgdPz IV, and for adding the new one-piece tracks in retrospect to existing boxes of (PzIV) kits. I’ve remarked before on PSC’s generosity of spirit in this respect, after all, the costs of doing it are relatively small.. Now I’m waiting eagerly for the SU-76.

  1. https://en.wikipedia.org/wiki/German_armored_fighting_vehicle_production_during_World_War_II gives total war production of Stug III A-E of 825 and F-G 8,593; of which only 366 were Fs (https://en.wikipedia.org/wiki/Sturmgesch%C3%BCtz_III). Aditionally 1,217 StuH 42s were produced with the 10.5cm Howitzer.
  2. This was rather unfair, as Guderian had opposed their production in the first place – but Hitler liked them, so they went ahead.
