rexford Posted October 28, 2001 Share Posted October 28, 2001 Analysis of published data strongly suggests that German APC and APCBC projectiles during the early war period were inferior to later ammunition. 88mm APCBC (9.54 kg) fired by Flak units 130mm penetration at 0 degrees and 0m to mid-1942 152mm by later war rounds 14.5% less penetration for early war APCBC 50mm L42 AP and APC rounds 70mm penetration at 0 degrees and 0m for AP 72mm penetration for APC 14.8% less penetration for AP when absence of caps is factored in (50mm AP has smaller HE burster than APC) 37mm L45 AP 51mm penetration at 0m and 0 degrees if combat round used in tests 64mm in DeMarre estimate from 75mm L48 adjusted for caps 20.0% less penetration 75mm L24 APCBC 50mm penetration at 0m and 0 degrees 53mm in DeMarre estimate from 75mm L48 5.7% decrease in penetration The early war 88mm APCBC and 50mm AP rounds appear to have about 15% less penetration due to metal characteristics Early war 37mm AP appears to have 20% less penetration due to less effective metal and a large HE burster (1.9% of total weight is HE filler, 0.2% of 75mm L48 APCBC is HE filler) 75mm L24 APCBC appears to have about 6% less penetration due to large HE burster (1.7% of total weight is HE filler, compared to 0.2% in 75mm L48 APCBC). The above data suggests that early war German ammo for 88mm, 50mm and 37mm guns was 15% less effective due to metal type, and large HE bursters reduced penetration by about 5%.

Jeff Duquette Posted October 28, 2001 Share Posted October 28, 2001 Great information as usual Rexford. By the way where can we get a copy of: WW II BALLISTICS: Armor and Gunnery, by L. Bird and R. Livingston Link to comment Share on other sites More sharing options...
