Oerlikon 204 GK
Oerlikon KAD
20 mm Rh202
All of these have the horrendus Oerlikon HVAP-T (DM43 for Rh202)
So far the only saviour from these horrid glass rounds were to either avoid playing these vehicles against ground vehicles using the 20mm:
U-SH 204 GK // R3 T20 FA-HS // TPK 6.41 // Ystervark // Marder A1-
As these vehicles lack the “DM63” APDS rounds, and only have the Shattermatic HVAP-T rounds.
But i found a sollution for the vehicles that suffers from the lack of an actual round that can deal with Light targets decently effectively!!! Its a AP-HEI with 40mm pen w 2.4g HE filler (for reference the L3/33 CC has 1g)
Current complete Bug reports:
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

Bug reports on all vehicles affected will show up the moment they are made!
It’s not APHE it’s HEAP. Explode before penetration not after(I think.)
anyways 20mm APHE wouldn’t exactly pen the most and so I think it’s fine
I too was thinking about suggesting the round. Both with and w/o tracer would be nice.

No need for a new round. They just need to tweak the post-pen damage of HVAP in general.
Why not have both lol, That way you can actually be a nousence to other light tanks the round doesent have enough pen to pen any heavier / medium tanks at the br, And its not as much filler or pen as the 35mm Oerlikon

No its a APHE, Also we are working on a Rework post for the HVAP since irl the round can pen a 10mm plate at 40~ degrees
The difference is 22 g for the 35mm Oerlikon vs 5.4 g So its not much at all its just to get a more solid AP munition and not the bouncy asf HVAP untill they can finally fix the HVAP, That for some reason works great on the M53/59 in the USSR TT
Suspicious how that works huh
For the APHEI-T

HVAP-T

nobady want to have a new AP-HE round. (Gajin wanted to fix APHE, but we players said no, so i dont want to have a downtier APHE autocannon)
Once again the pen isnt near the 35mm Oerlikon neither is the explosive filler, The game has been traumatised by the 35mm This is a way lower filler amount and penetration, But it gives you a okay round to deal with M18s or Other lighter armoured Vehicles,
APHE? I just need to aim perfectly on the cupula, and im dead. No matter how big the round is, APHE is APHE
The mentioned round penetrates 40-50mm it cant penetrate the cupola of any tanks at its tier.
And again the filler is alike that of the L3 20mm APHE, its not much, you are mostly relying on the AP aspect of the round, and at least its not HVAP,

The penetration calculation is for the AP-T (HVAP) btw.
PSA/PLA (APHEI/APHEI-T) would be like this;

based on;
Just for the record, KAA is the newer designation for Type 204GK - they’re the same cannon.
Some extra info on the AP-T (HVAP);
HLA is a bit different from PKLH but not by much…
(HLA = Hartkern, Leuchtspur, A-Serie // Hardcore, Tracer, A-Series [i.e. 20mm])
HLA is also a bit newer as PKLH as it uses the “new” Oerlikon naming schene.
~15mm at 60° (from the vertical) at 800m is insane compared to how low it is in WT.
Which can’t even penetrate that much at point blank range.
In WT it’s practically worse than using solid shot.
So instead of having a better round Gaijin made any vehicle using it much worse.
With the correct implemenation, 20mm HVAP would be quite capable and you can actually destroy BMPs instead of tickling them.

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