 |
| | History | |
|---|
| | As the war progressed there was an increasing requirement to have harder hitting anti tank guns with higher velocity shells, this required an increase in length of the standard 75mm Pak 39/40 from L/48 to L/60.
The 7.5cm Kwk 42 was a version provided for tanks, specifically the Panther and was semi automatic with electric firing. |

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.
