The Panzer IV G was to be the first tank installed with the 7.5cm KwK40 L/43 gun in 1942. However, the Wehrmacht needed to urgently counteract the thicker armor of the T-34 and KV-1 so this gun was also fitted to some Ausf. F tanks (where it was known as the F2). A total of 175 F2 tanks were produced from March to July 1942.
