Belgium Canon de 47 antichars SA-FRC

Showing the details of the shells used(where known)   Tweet Weapon Details Canon de 47 antichars SA-FRC (Anti Tank Gun) History Well designed but heavy weapon, provided better penetration than the British 2pdr giving 47mm/30° @ 300 metres. Because of its weight it required vehicle help to reposition. Manufactured 1931 - 1939 Calibre 47mm Length L/34   AP (AP Armor Piercing) 47mm 1.5Kg 720M/Sec Quoted Penetration 47mm @ 300mtr/30° ( ≈ 54mm/0°) Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.14 0.29 0.61 1.34 2.24 3.37 4.84 6.82 Penetration(mm@30°) 58 53 47 39 32 25 20 15 Penetration(mm@0°) 68 62 55 46 38 30 24 18 Hit Probability(%) 98 98 98 90 57 25 8 3 HE (HE High Explosive) 47mm 1.5Kg 450M/Sec ≈0.225Kg explosive Maximum Range not shown as gun elevation is limited Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.23 0.46 0.97 2.14 3.59 5.39 7.75 10.91 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.23 0.46 0.97 2.14 3.59 5.39 7.75 10.91 Hit Probability(%) 98 98 98 60 22 6 2 0 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 15 mtr  Armour Penetration inc roof at 1 mtr 0 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 15 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 not cause any significant armour damage.

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.
