Armour penetration figures needed

[Der Teddy Bar]

I am after the armour penetration in millimetres for SHIII’s small calibre weapons, such as the 20mm Oerlikon, 40mm Bofors, 2 pounder, 3” etc


Thanks in advance

Second World War

During WWII, projectiles used highly alloyed steels containing nickel-chromium-molybdenum, although in Germany this had to be changed to a silicon-manganese-chromium based alloy when those grades became scarce. The latter alloy, although able to be hardened to the same level, was more brittle and had a tendency to shatter on striking highly sloped armour. The shattered shot lowered penetration, or resulted in total penetration failure, for APHE projectiles this could result in premature detonation of the HE filling. Highly advanced and precise methods of differentially hardening the projectile were developed during this period, especially but the German armament industry. The resulting projectiles gradual change from high hardness (low toughness) at the head, to a tough (less hard) rear and were much less likely to fail on impact.

<cut middle section>

Early WWII era uncapped AP projectiles were able to penetrate about 2 times their calibre at close range (100 m). At longer ranges (500-1000 m) this dropped 1.5-1.1 calibres due to the poor ballistic shaped and higher drag of the smaller diameter early projectiles. Later in the conflict APCBC fired at close range (100 m) from large calibre guns (75-128mm) were able to penetrate a much greater thickness of armour in relation to their calibre (2.5 times) and also a greater thickness (2-1.75 times) at longer ranges (1500-2000 m).

Sfinx,
Thanks. I found the British section :D
