Isn't that British O.B. partial penetration criteria, not US Naval Limit? So the armor would likely be M.Q. not 237 BHN armor.Yoozername wrote:The "various" appears to be, left to right, 7,5cm Pzgr 39@ 2400M/s, 7,5cm Pzgr39 @2800M/s, Pak 41 (squeeze gun), 50mm Pak AP, KWK 50mm Pzgr 40, 88mm Flak 36 APCBC, and a 7,62 cm Pak 36 firing Pzgr 40.whelm wrote:

I would expect them to be using standard US test Armor and it says 50% success criteria. Very interesting to compare with other data.
Late 42 or sometime in 43 I believe they switched from an 80% chance to a 50% chance in testing/calculations.Mobius wrote:These are great. But I'll have to look up the British/Canadian definition of perforation.
