L/48 was designed in 1941, manufactured by Alkett based on the existing fully tracked PzKpfw III and was in use from 1942 to 1945. The vehicle was powered by Maybach 'HL120 TRM' petrol powerplant producing 300 HP which could drive the vehicle on roads at up to 25 mph with a range of about 88 miles before refuelling. Its cross country performance was good providing a max speed of about 13 mph and a range of about 35 miles. It was armed with 2 light machine guns. Its main armament consisted of a 7.5cm StuK 39/40 L/48 which could penetrate 112 mm of flat plate at 800 metres Designed as an infantry support vehicle in 1936, it was to utilise the PzKpfw III chassis in a vehicle with a very low profile.

An explosion within 6 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 16 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 1 mm of the tank armour including the roof.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
