Re: 150mm KwK 44 L/38 and 170mm KwK 44 L/71
 

Another thing to keep in mind with these kind of exercises is this is in the realm of Alternate History or Fantasy if you will. So in order for these beasties to arise, other things would be happening as well. Just in gun technology alone there would advances in metalurgy, ammuntion, optics and stabalization. Put in this context some of these Nazi Nightmares one could suppose might have come to life.

As for the monster guns 12.8cm and above, the thing I find most impracticial is having to load separate warhead and charge loads. For a Battle Tank single round makes more sense in terms of speed of loading, storage within the vehicle and safety. This is why I chose to only create 10cm & 10.5cm Guns.

170mm gun looking a bit like this perhaps..

Weapon size for that one (175mm) is 12.

In my attempts at creating a workable post 40s German Army I too came across the concept of the 170/175mm gun. As far as I remember it was meant to be mounted on tank destroyers. The Krokodil (PzJaeger variant of the E-100).

The base values for the gun are as follows:

Weap. 170mm KWK 44.
WC: 7
ACC: 17
WS: 12
HE Pen.: 4
HE K.: 25
AP Pen.: 35
AP K.: 0
Sab. Pen.: 0}
Sab. Rng.: 0}
HEAT Pen.: 0}
Wpn. Rng.: 140

As my timeline is a little longer I thought it unnecessary to alot any Sabot or Heat rounds to the weapon. These figures are what I call the "base figures" as they remain constant (with perhaps some tinkering with the range of the weapon) throughout. The only significant changes occuring to the Sabot and HEAT capabilities of the weapon. Armour Piercing being phased out of course.

Now the question is what does one do if they want to project these weapons into the 60s, 70s, 80s and 90s?

If anyone needs any data on projected 110mm, 128mm and 150mm guns, I have that too.
