WW II Ballistics Tank Gun Penetration - Germany

The following is my choice of German gun penetration data.  Penetration in this case is known as the Naval Ballistic Limit Penetration criteria (NBL) or in the case of British data 'The Thickness against Critical Velocity for Perforation'.  Either criteria is based on a 50% probability of a successful penetration. A successful penetration for the US is one where more than 50% of the shell mass (excluding windscreen) passes through the armor.  For British it is at least 20% of the shell mass passes through the armor 'as a free missile'.  The criteria statistically are almost the same.   Tests of German guns that produced firing graphs or curves were generally carried out under the British system. Firing tables were made from these graphs and distributed to various boards. Some of these tables were sent to Aberdeen and are thus called Aberdeen data.

Czech pre-war 37mm and 47mm AP caps were elongated and rather large. In some ways this acted like a ballistic cap and had better ballistics than German 37mm and 50mm shells.
