When WWII broke out in 1939, Germany relied heavily on the 3.7cm PaK 36 antitank gun. However, this puny weapon was no match for armored vehicles like the French Char B1 or British Matilda II. One solution was to mount the more powerful Skoda 4.7cm PaK(t) gun on the chassis of the Panzer I Ausf. B. This had a double advantage – a more capable antitank weapon was created, and it permitted an extended use of obsolete Panzer I tank chassis. Called the Panzerjäger I, this new vehicle was Germany’s first of many tank destroyer designs. Between March 1940 and February 1941, 202 such Panzerjäger I vehicles were converted in time for service in the Battle of France, in North Africa, and in the invasion of Russia. By the end of 1943, the Panzerjäger I had been phased out. The Skoda 4.7cm PaK(t) gun was mounted in an open-topped Panzer I fighting compartment with its original gun shield still affixed.
