What was the craziest German Design during World War 2?

There is an extraordinary, incredible book, presently unfortunately no longer available called "Our Tank is Fight" that gives a diverting take a gander at each German clear-cut advantage. At one time, the Germans arranged a circling space station.

I was going to utilize the Natter as my recommendation for the craziest weapon structure yet it has just been picked twice.

Along these lines, I will designate the V3 weapon. This was a huge gun manufactured underground intended to fling immensely substantial shells at England. It was planned so that poles worked at an edge to the primary barrel would be terminated with high explosives at the right time to drive the shot quicker and further. It depended on an old hypothesis from the 1850s sent by the creator of the cruiser.
