Panzerkampfwagen IV with 8.8cm Pak 43
Drawing from Panzerkampfwagen IV and Its Variants
As allied armor (especially Soviet) became more resistant to
armor piercing ammunition, and as the war was becoming increasingly
a defensive one for the Germans, tank destroyers with more powerful
armaments were sought. Towards this end, Krupp attempted to mount
the 8.8cm Pak 43/3 L/71 on a Panzer IV Ausf. J chassis. This gun was
essentially the same as the one found on the Jagdpanther and Tiger II, and
represented one of the best anti-tank guns produced during World War II.
Calculations apparently showed that the vehicle's weight exceeded the
tolerance of the suspension, and the "Panzerjaeger IV mit 8.8cm Pak 43/3
L/71" remained a paper project.
