General Information
The Semovente da 75/46 su scafo di carro M43 based on the existing fully tracked M13/40 and was in use from 1943.

The vehicle was powered by FIAT-SPA '15TB M-15 diesel V8' diesel powerplant producing 170 HP which could drive the vehicle on roads at up to 22 mph with a range of about 112 miles before refuelling. Its cross country performance was good providing a max speed of about 12 mph and a range of about 44 miles.

It was armed with 1 light machine gun. Its main armament consisted of an Cannone contracarro da 75/46 which could penetrate 119 mm of flat plate at 400 metres

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.
