Germany 12.8cm Flak 40 12.8cm Flugabwehrkanone 40 (translates as Anti Aircraft Gun)

Showing the details of the shells used(where known)   Tweet Weapon Details 12.8cm Flak 40 12.8cm Flugabwehrkanone 40 (translates as Anti Aircraft Gun) History An enlarged 10.5cm Flak 40 which were mostly in fixed positions, however a few of the mobile transporters were manufactured, but at 15 metres long these were looked on as a waste of resources. Manufacturer Rheinmetal-Borsig Manufactured 1942 - 1945 Calibre 128mm Length L/53 12.8cm Sprgr Patr L/4.5 (HE High Explosive) 128mm 26.02Kg 880M/Sec 3.400Kg explosive Maximum Range 14800 Mtr Range(Mtr) 1000 2000 3000 4000 5000 6000 7000 8000 Flight Time(Secs) 1.23 2.69 4.45 6.61 9.32 12.83 17.56 24.24 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.11 0.23 0.47 0.97 1.5 2.08 2.69 3.36 Hit Probability(%) 98 98 98 98 88 64 41 25 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 4 mtr Burst radius Infantry in open 66% kill 9 mtr Burst radius Infantry in open 33% kill 23 mtr  Armour Penetration inc roof at 1 mtr 10 mm An explosion within 4 mtr of infantry in the open will cause 99% casualties - lethal. An explosion within 9 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 23 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 10 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.
