The StuG started development before the war and was in full production by 1940. Designated an Assault Gun it was designed round a Panzer III chassis but no turret, this gave it an extremely low profile. It's role was to support infantry as they followed close behind the panzer assaults. But the Assault gun soon proved to be very versatile, in Russia they were often called upon to provide an anti-tank role.
The StuG would be produced throughout the war. The bombing of the factory in 1943 forced a change in design to a Panzer IV Chassis as production was moved to a different facility. To deal with the better armour that the Germans were now facing it was found the StuG with its larger crew compartment could accommodate the 75mm Pak40 allowing it to pack enough punch to knock out the new Soviet T34s.
The StuG became the most produced armoured fighting vehicle of the war!
In this episode I'm talking to John Phillips and we're talking StuG, Jon owns one and currently in the process of restoring it.
