Panzerkampfwagen I Ausf F (PzKpfw IF)
Originally given the prototype designation VK1801, the final attempt to design a new Panzer I tank was the Ausf F, a 21 ton heavily armored infantry assault tank. Strictly designed to mount the maximum armor protection possible, 80 mm frontal plate was provided with 50 mm on the side and rear and 25 mm top and bottom, although with negligible slope. The suspension and powerplant of the Ausf C were used, but with a simpler transmission with only 4 forward gears plus reverse. Length was increased to 4.38 m and width to 2.64 m to accommodate wider tracks to lessen ground pressure while height was only lightly greater at 2.05 m. Performance suffered with speed reduced to 25 km/h and range to 150 km. A pair of MG34 coaxial machine guns provided the armament. While invulnerable to most antitank weapons of its time, its low speed and weak armament limited it to expressly anti-infantry operations. Only thirty were produced by Krauss-Maffei from April through December 1942, and most served on the Eastern Front.
