So i’ve contracted the silly and now I want to suggest the mörser gerät 40 (not really don’t add this please) a series of 7 vehicles could maybe make them possible with the new multi vehicle system (they are not possible)
SPG with the 60cm gun
Anticipating thewar, the German Army recognized the need to overcome numerous heavily fortified positions, many of which were reinforced with concrete and buried underground. tis led to the creation of our fellow right here by Rheinmetall which the first units delivered from november 1940 to august 1941.
This guy had 600mm barrel with a range of around 6km which could change with the use of heavier or lighter rounds.
But this was undesirable since it left crews exposed to enemy counterbattery fire, so it was ordered in February 1941 to extend the range as much as possible, how could this be done?
by a longer barrel and a smaller caliber and because designing and producing an entire new chassis was expensive they decided at Rheinmetall that they would just change the gun
to a 54cm barrel.

SPG with the 54cm gun
Even after the highly problematic design of the 54cm mortar and after being cancelled, the firing trials were finished and the current leader which I don’t know if it can be mentioned here ordered the production of the first 3 planned vehicles, which vehicles I, IV and V were adapted for the 54cm gun but never used it due to lack of ammunition.
I end the history section here since im lazy.
So let’s say the Gaijin higher ups get hit with the biggest famine ever, need money ASAP and decide to turn to this thing, which by the way I think it’s impossible to add due to:
I don’t know how would they program 18 gunners but ok.
You guys are free to discuss what BR would this thing go to and maybe if some of you are crazy enough I can try to make a suggestion for this. But let’s be honest this would the worst vehicle in the game since no way it goes to 1.0 and even there it would become a building sized CAS magnet.
