WW2 Tank Gun comparison
I thought it would be interesting to compare the performance, potency energy of the premier high velocity tank guns of the west in WW2 in depth detail, so here we go.
8.8cm KwK43 L/71
Projectile weight: 10.4 kg (APCBC)
Sectional Density: 1.910
Muzzle Velocity: 1000 m/s
Total Kinetic Energy: 5200 KJ
Kinetic Energy pr. cm^2: 85.49 KJ
7.5cm KwK42 L/70
Projectile weight: 6.8 kg (APCBC)
Sectional Density: 1.719
Muzzle Velocity: 936 m/s
Total Kinetic Energy: 2979 KJ
Kinetic Energy pr. cm^2: 67.43 KJ
7.62cm 17pdr
Projectile weight: 7.7 kg (AP)
Sectional Density: 1.886
Muzzle Velocity: 883 m/s
Total Kinetic Energy: 3001 KJ
Kinetic Energy pr. cm^2: 65.8 KJ
9.0cm M3 L/53
Projectile Weight: 10.94 kg (APBC)
Sectional Density: 1.921
Muzzle Velocity: 853 m/s
Total Kinetic Energy: 3980 KJ
Kinetic Energy pr. cm^2: 62.56 KJ
8.8cm KwK36 L/56

7.6cm M1 L/55
Projectile weight: 7.0 kg (APCBC)
Sectional Density: 1.724
Muzzle Velocity: 792 m/s
Total Kinetic Energy: 2195 KJ
Kinetic Energy pr. cm^2: 48.38 KJ
7.5cm KwK40 L/48
Projectile weight: 6.8 kg (APCBC)
Sectional Density: 1.719
Muzzle Velocity: 790 m/s
Total Kinetic Energy: 2122 KJ
Kinetic Energy pr. cm^2: 48.03 KJ
The best performers in terms of their size compared to their potency energy are clearly the 8.8cm KwK43, 7.5cm KwK42 7.62cm 17pdr, these three also feature the best penetrative performance of all the guns above which is also proportionate to their KE pr. cm^2.
Next I'll post the Aberdeen test results for each gun against 240 BHN RHA armour.
Well, the good thing about the 12.8 was that it held its energy better over large distances. With the arrival of the IS series, the 8.8 was insufficient over large distances. Plus, the 12.8 was better at destroying fortifications, again over large distances. As such the JagdTiger was excellent if used in the right way: for long range engagements, never close combat.
Those anyone have any background information on the German 10.5 cm tank cannon? It was to be used with the latest Tiger IIs and E-75s, perhaps also with the JagdPanther II.
Do you think it also had two piece rounds?

Absolutely Freebird, I'll post it as soon as I get home.
You know I have to ask, are you Schwarzpanzer mr. Tempest ??
As for your gun comparison, there are so many inaccuracies in it that it can't be used at all. For one the German 128mm L/55 KwK/PaK44 fired a 28.3 kg APCBC projectile at 845 m/s, making it superior to all other AT guns fielded during the war. Next is the 10.5cm regular solid AP projectile, it weighes 15.56 kg.
Besides this the Germans were working on a 155mm AT gun even more powerful than the 128mm PaK44, to be used on the E-100 design which was near completion during the end of the war.
