General Details Specifications Operational Date(s) 1943 - 1945 Ordnance classification SdKfz 124 Quantity Produced 676 Weight 11 tonne Crew 5 M.G's small 1 M.G's large(>10mm) n/a Length 4.81 mtr Width 2.28 mtr Height 2.30 mtr Engine Details/Performance Max Road Speed 25 mph Max Cross Country Speed 12 mph Range Road 138 miles Range Cross Country 55 miles Fuel Type Petrol Fuel Capacity unknown Horse Power 140 hp Power/Weight 12 hp/tonne General Information The 10.5cm le.F.H 18/2 Gw II(A,B,C,F) was designed in 1942, manufactured by FAMO based on the existing fully tracked PzKpfw II and was in use from 1943 to 1945. The vehicle was powered by Maybach 'HL62TR' petrol powerplant producing 140 HP which could drive the vehicle on roads at up to 25 mph with a range of about 138 miles before refuelling. Its cross country performance was good providing a max speed of about 12 mph and a range of about 55 miles. It was armed with 1 light machine gun. Its main armament consisted of a 10.5cm le.F.H 18/2 L/26 which could penetrate 114 mm of flat plate at 800 metres Slightly lengthened Panzer II chassis with the engine moved forward with a number of redesigns over the Panzer II. This was a very successful design and was used in most theatres of war.

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.
