Manufactured 1932 - Present Calibre 40mm Length L/56 Rate of Fire 120 rpm   No ammunition details available Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) Penetration(mm@30°) 0 Penetration(mm@0°) Hit Probability(%)

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.
