7.5 cm Pak 40

In 1939 the German High Command learned of the development of new, heavier and better armoured Soviet tanks, which led to a requirement for a new anti-tank gun capable of stopping them. Rheinmetall-Borsig and Krupp presented their designs and finally Rheinmetall’s was chosen, basically, because the new 75mm gun was a larger version of the 50mm Pak-38, which would greatly speed up development and production. Of course, there were differences between the two guns, not only in caliber, but mainly in the materials used in their manufacture. The new gun was homologated in 1940 under designation “7.5 cm Panzerabwehrkanone 40“, although it would be known worldwide as the “7.5 cm Pak 40“.
