Weapon Details 85 mm ZiS-S-53 M1939 L/55 (Tank Gun) History Developed from the 85 mm air defense gun M1939 (52-K) this was the heavier tank gun used in vehicles such as the T34/85 Manufactured 1939 - 1945 Calibre 85mm Length L/55 Rate of Fire 10 rpm   Ammunition Details Name/Id Calibre Weight MVelocity Explosive Content 85mm/L52 (D-5T) (AP Armor Piercing) 85mm 9.2Kg 792M/Sec Quoted Penetration 125mm @ 500mtr/30° ( ≈ 144mm/0°) Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.13 0.26 0.53 1.12 1.76 2.49 3.3 4.22 Penetration(mm@30°) 156 146 135 120 107 94 82 71 Penetration(mm@0°) 181 169 156 139 124 109 95 83 Hit Probability(%) 98 98 98 96 77 48 25 15 85mm/L52 (D-5T) (APCR Armor Piercing Composite Rigid) 85mm 5.3Kg 1050M/Sec Quoted Penetration 136mm @ 500mtr/30° ( ≈ 157mm/0°) Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.1 0.2 0.4 0.86 1.38 1.98 2.67 3.48 Penetration(mm@30°) 144 133 120 104 90 77 64 52 Penetration(mm@0°) 167 154 139 121 104 89 74 61 Hit Probability(%) 98 98 98 98 90 69 41 25 85mm/L52 (D-5T) HE (HE High Explosive) 85mm 9.54Kg 793M/Sec 0.741Kg explosive Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.13 0.26 0.54 1.14 1.83 2.62 3.53 4.61 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.13 0.26 0.54 1.14 1.83 2.62 3.53 4.61 Hit Probability(%) 98 98 98 96 74 41 22 8 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 2 mtr Burst radius Infantry in open 66% kill 5 mtr Burst radius Infantry in open 33% kill 14 mtr  Armour Penetration inc roof at 1 mtr 2 mm An explosion within 2 mtr of infantry in the open will cause 99% casualties - lethal. An explosion within 5 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 14 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 2 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.
