Italy Autocannone da 75/27 CK (Ceirano 50 CMA)

Tweet The Autocannone da 75/27 CK (Ceirano 50 CMA) was designed in 1926, manufactured by Arsenale Costruzioni Artiglierie of Naples based on the existing 4 x 2 drive Ceirano 50 CMA truck and was in use from 1927 to 1943.

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 93 mm of flat plate at 100 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.
