The Semovente da 105/25 su scafo di carro M43 was a Self Propelled Anti Tank vehicle designed in 1942, manufactured by Fiat-Ansaldo, it was based on the fully tracked M13/40 chassis and was in use from 1943 to 1945. It was commonly called a Bassotto - Dachshund.

It was commonly called a Bassotto - Dachshund. The vehicle was powered by FIAT-SPA '15TB M42' petrol powerplant producing 192 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. Its main armament consisted of an Cannone contracarro da 105/25 which could penetrate 62.3 mm of flat plate at 400 metres. The Semovente 105/25 was a self propelled gun based on a widened M15/42 chassis. The vehicle was powered by a Fiat diesel engine of 192hp the front drive sprockets took the track under eight road wheels on two bogies, round the rear idler and back via three return rollers.

This allows direct comparison between all nations' guns. Original national test figures would be higher for some nations due to different criteria: German: 1.00? (baseline - strictest) British: 1.02? (slightly looser) American: 1.05? (50% mass through plate) Soviet: 1.10? (75% mass through plate) For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents, and a German gun showing 120mm would be published as 120mm in German documents. The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful. National Testing Standards German: 1.00? - Complete penetration, fuze functions (strictest) British: 1.02? - Complete penetration American: 1.05? - 50% of shell mass through plate Soviet: 1.10? - 75% of shell mass through plate All database figures are normalized to German standard for direct comparison. Multiply by the factor above to see original national test figures.

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.
