Manufactured 1943 - 1960 Calibre 57mm Length L/50   Shot, AP, Mks 1 to 7 (AP Armor Piercing) 57mm 2.86Kg 853M/Sec Quoted Penetration 68mm@915m Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.12 0.24 0.5 1.09 1.78 2.61 3.61 4.86 Penetration(mm@30°) 90 83 74 63 53 44 35 28 Penetration(mm@0°) 105 96 86 73 62 51 41 33 Hit Probability(%) 98 98 98 98 77 41 22 8 Shell, HE, Mk 10T (HE High Explosive) 57mm 3Kg 820M/Sec ≈0.45Kg explosive Maximum Range not shown as gun elevation is limited Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.12 0.25 0.52 1.14 1.85 2.71 3.76 5.06 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.12 0.25 0.52 1.14 1.85 2.71 3.76 5.06 Hit Probability(%) 98 98 98 96 74 39 22 6 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 3 mtr Burst radius Infantry in open 66% kill 6 mtr Burst radius Infantry in open 33% kill 17 mtr  Armour Penetration inc roof at 1 mtr 1 mm An explosion within 3 mtr of infantry in the open will cause 99% casualties - lethal. An explosion within 6 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 17 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 1 mm of the tank armour including the roof.

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.
