ID:0047652 28/Aug/16 Fix ammunition of Brummbär (150mm J.Gr.39 HL/A)



the penetration values of the Jgr. 39 HL/A were reduced from 250mm (@90°) to 160mm (@90°) short time ago. Were ever the 250mm value came from, 160mm is still the wrong penetration value and should be fixed. That's how they look at the moment in game (German language but you get the idea):

J.Gr.39 HLA.jpg


160mm is the value you find in German documentations often, but the German army always considered values measured with an 30°/60° angle. The real value @90° should be 185mm therefor.


See this documents as a proof:


First sentence translated "Penetration values refer to firing at an angle a = 60°."



Underlined sentence translated: "Penetration value: 160mm thick armourplate with 15cm Jgr. 39 HL/A"



This source is considering an 90° angle, therfor the value of the 15cm Jgr. 39 HL/A also known as 150L11 HEAT is 185mm.



Look at the third bar from right.



You can read at the top, that the considered angle is 30° (/60°).
