Old Meets New

The Panzer I Ausf F was the last development of the tiny Panzer I series. Following the 1939 Polish campaign the Germans decided they needed a well-armored infantry support tank. In September 1939 work started on designing a new heavily armored infantry assault tank based on the Panzer I. This new 21-ton tanks was originally given the prototype designation VK1801, but was later officially designated Panzer I ausf F.

It varied from early Panzer I design with increased armoured and new suspension. The design brief called for the tank to mount the maximum armour protection possible. 

It has 80mm frontal armour, 50mm on the side and rear, and 25mm top and bottom. However, the armour had little or no slope. Interleaved wheels with torsion bar suspension and wide tracks were used to disperse the increase in weight. It was powered by a Maybach HL 45P engine giving a top speed of 25 kph and a range of up to 150 km.
