IS-6 - Should it get BR-471D

With the BR-471B shell now only having 199mm of pen flat at 10m the IS-6 can only pen the Tiger 2H turret reliably from 350m.

 

Giving the IS-6 BR-417D would be historical as the tank was designed early and then late 1944, the same as the IS-3 and IS-4 which have BR-417D. This would allow the IS-6 to be able to reliably kill Tiger 2Hs from the front again.

I can only find info on BR471B being from early 1945, is there any document that says that the is6 was equiped with or tested with BR471D?

Hmm that is what I'm looking for. It's really difficult to find any information about ammunition types for WW2 era tank guns, especially Soviet.

 

I don't even think tanks having the D shell is chosen by historical use. Considering the IS-3 in game has the D shell but it isn't the IS-3m judging by the name and lack of fuel tanks that can be dropped. 

 

Even if it didn't have it, honestly from a balance perspective being stuck with a long reload and only 199mm of pen at 7.3 sucks.

Why? It's not like the Tiger II will be able to easily destroy an IS-6 from more than 350m hitting that tiny spot on the turret...

At the time the IS-6 prototype existed the only rounds available were the BR-471 and BR-471B.

The BR-471D was only available in the mid 50s.

What the IS-6 lacks in penetration it makes up for it with mobility and better RoF compared to the IS-3.

Also, not only does the BR-471B penetrate front from 400m, it will also penetrate the side if the turret is just slightly angled.

 

If historical accurate neither 122mm AP or APBC round would be able to penetrate more than 165mm of ductile armor, making the Tiger II completely immune against both 100mm and 122mm WW2 ammunition from the front.

With that the Tiger II could go head to head against the IS-3 and the Tiger armed with the 105mm gun would even be able to penetrate the IS-3s front armor.

Only the 122mm BR-471D round should be able to penetrate the turret of the Tiger II but it would have barely enough penetration to penetrate the turret of the T29/30/34.

 

Without BR-471D it would look like this:

IS-2 1944 <<<< IS-3 < IS-6 < Tiger II H < T34 = 105 Tiger II

 

With BR-471D it would look like this:

Tiger II H < IS-3 < IS-6 < T34 = 105 Tiger II
