The vehicle was powered by Ceirano '50C' petrol powerplant producing 53 HP which could drive the vehicle on roads at up to 15 mph with a range of about 150 miles before refuelling. Its cross country performance was poor providing a max speed of about 3 mph and a range of about 30 miles.
Its main armament consisted of an Autocannone da 75/27 which could penetrate 78 mm of flat plate at 400 metres
This vehicle was a marriage of the Autocannone da 75/27 Anti Aircraft gun and the Ceirano 50 CMA truck, hence providing mobile AA and A/T support. | |

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.
