The vehicle was powered by FIAT-SPA 'SPA petrol' petrol powerplant producing 250 HP which could drive the vehicle on roads at up to 20 mph with a range of about 0 miles before refuelling. Its cross country performance was good providing a max speed of about 11 mph and a range of about 0 miles.
Its main armament consisted of an Cannone contracarro da 149/40 M35 which could penetrate 388 mm of flat plate at 200 metres
The Semovente 149/40 was a self propelled gun redesigned from the P40 chassis.
The vehicle was powered by a Fiat petrol engine of 240hp the front drive sprockets took the track under eight road wheels on two bogies, round the rear idler and back via three return rollers.
The gun was a 149mm L/40 howitzer mounted in a box shaped superstructure. | |

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.
