began looking at ways to improve the design for a future version. Based on the latest Allied tank designs, however, it was clear that simply increasing the armor on the VK 45.01 (P) would not be enough for the tank to remain competitive. It needed to have both more weight and more maneuverability. What initially began as a single vehicle, entitled "Typ 180" grew into a series of five different vehicles, requiring the development of two hull configurations: the Hinten with its turret at the back (as shown in the picture on top) and the Vorne with its turret on the front. Both an electric and a hydraulic drive system, and four different engines. The overall project came to be known as ''VK 45.02 (P).''
