Germany’s first attempt at creating a heavy tank was the Neubau-Fahrzeug (literally, “New Construction Vehicle”), although the design was in fact too ponderous for the blitzkrieg tactics that were being developed. Nevertheless, a total of five vehicles were made, and three of them saw combat in Norway in 1940. The multi-turreted Neubau-Fahrzeug was conceived in 1933, with the main armaments being a 7.5cm KwK L/24 gun and coaxial 3.7cm KwK L/45 gun. There were two other turrets fitted front and rear with machine guns. While the Neubau-Fahrzeug offered good propaganda value, the vehicle operated by a six-man crew wasn’t truly effective in combat. Three tanks fought in a specially created Panzerabteilung in Norway, although one was demolished after getting stuck in a swamp. By 1942, all these heavy tanks had been scrapped.
