Hitler's supertank, which failed (Photo)

And part of the projects that were accomplished was a complete failure. Such was the case of the mega tank called “Gustav”, which began to be built after France's invasion in 1941.

There was a four - story machine weighing 1350 tons, and from its mammoth ball, it was able to shoot up to 4,500 pounds [4,500 kg] of shells.

The original goal was to hit Great Britain from the French, Belgian, and Dutch coasts but never realized. In the spring of 1942, it was only tested in the battle of Sevastopol in Crime, where it fired 300 shells on the city, destroying it almost completely.

Large resources were needed to activate the machine, but a staff of 2,000 were needed. “Gustav” moved onto the tracks, but it wasn't a train, and for the construction of the railway infrastructure specifically for it, it needed more sforco and expenses.

It was the enormous cost of moving and active in battle but also the size of the tank, which made it an easy target for the enemy aviation, forced the Nazis to give up this tank and focus more on other weapons.
