Comparing: Pz.Kpfw. III Ausf. K vs. M7

This tank was developed on the basis of the later Pz.Kpfw.III Ausf. J chassis, combining it with the Pz.Kpfw.IV Ausf. F2 turret and a 75-mm gun. The first design plans were completed by the end of December 1941. Manufacturing began, but the vehicle proved overly complex and production was soon canceled. A total of 50 vehicles were completed and used as command vehicles. They featured 50-mm guns; the 75-mm guns were never mounted.

Development started in 1941. Initially, the vehicle was developed as a light tank; however, as the model gradually received extra armor and armaments, it was reclassified as a medium tank. Production of the M7 started by the fall of 1942. However, since the M7 was inferior to the mass-produced M4 Sherman in all parameters except speed and dimensions, the production was stopped. A total of 7 vehicles were produced.
