The Panzer IV was intended to carry a gun that could be used in support of infantry or other tanks, and was initially armed with a short-barreled 75 mm howitzer to fire high explosive (HE) fragmentation shells. In 1941 an average of 39 Panzer IV model tanks per month were built, and this rose to 83 in 1942, 252 in 1943, and 300 in 1944.
