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.

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.
