History
The Jagdpanther was preceded by two attempts at mounting an 8.8 cm gun as a self-propelled anti-tank weapon; Ferdinand - also known as Panzerjäger Tiger (P) - These used the ninety-one leftover Porsche-built VK 45.01 (P) chassis from the Tiger tank competition it lost to Henschel in 1942, and the Nashorn on the Geschützwagen III/IV (which used a combination of the Panzer III and Panzer IV components) chassis. Ferdinand proved to be too heavy, and Nashorn lightly armoured and under-powered.
