Oerlikon 20mm HVAP-T is Useless (And We found the Round That can Fix It!)

[KillaKiwi]

The Marder A1 is 7.7 and used HVAP till the 90s.

Most vehicles using the 20mm Oerlikon are 4.7 - 6.7, The Bmp is abit over that-

Well, for the most part they are just SPAAs.

The AMX-10P, R3 T20 FA-HS, U-SH 204 GK, Wiesel 1A4 are all armoured reconisence/Fighting vehicles

TPK 6.41, Ystervark are SPAA platforms

The 20mm HVAP is a complete disaster. I’m using the French truck with two 20mm cannons, and it’s incapable of destroying even other SPAAs with 8mm armor, as many of the bullets don’t penetrate.

20mm DM43 Penetration

I have started using the Marder A1 and the poor penetration of the 20mm barrel seemed quite strange to me, especially using tungsten carbide bullets and being bullets from the 60s. First I asked a colleague who has created a suggestion to change the horrible formula for calculating penetrations for a better one, and in the calculation of the 20mm DM43 ammunition it gave a penetration of 91mm at 0º and 0 meters, then I found some images on several sites. In this image there are several penetra…

Updated the post to include completed bug reports by me and @AspectOfTheRAGE

@karnitin75

The U-SH 204GK currently lacks access to APHEI and APHEI-T

TPK 6.41 - Lacking Oerlikon PSA & PLA Type APHEI/-T

R3 T20 FA-HS - Lacking Oerlikon PSA & PLA Type APHEI/-T

The TPK is highly bipolar. Either you cannot kill an SPAA with 10mm of armour or you roll up to a jumbo and kill it through the side. No inbetween

They just need to tweak the post-pen damage of HVAP in general.

The big problem with HVAP is not the post-pen. It’s the fact that using it is a shatterfest pretty much.
I will add to this I once expended the whole AMX-30 20mm coax belt into the side of a Begleitpanzer from point blank and the guy survived because the HVAP shattered on about 80% of the hits.
