WI: Tiger tank with 105mm gun

[Vjacheslav Malyshev]

The IS3's gun was actually picked primarily for use against heavy fortifications rather than anti-tank use. The weapon picked had inferior AT performance but carried much more HE.

At the time the 122mm could pentrate the Panther a greater range than the 100mm could. The 100mm penetration was only marginally better against flat armor at the time.

I think a lot of things could kill the early, stepped-hull JS-2. The straight-nosed one is a different story. I think the L/71 could do it with difficulty.

If the war is going well enough for the Nazis and they don't get nuked, then we get to see the JS-3 put into action which was specifically designed to be 100% immune to all German tank guns (well, I'm not sure about the 12,8) at any distance. Of course the JS-3 had some severe technical issues and there were serious problems with the weld seams (but where have we seen before the phenomenon of uber-tanks being pushed into service despite these exact problems? ).

The IS-3 is frontally immune to the German 105mm.
