Why doesn't the Military build super Heavy Tanks?

Answer 1

The main reason for building the super heavy tanks was immunity from enemy fire. A super heavy tank would have featured thick armor that would be impenetrable to most WWII weapons. Being able to move around on the battlefield without fearing enemy fire would have been quite an advantage, but unfortunately it wasn't possible to be immune from everything. Enemy aircraft would surely target a super heavy tank on the battlefield, since it would be a big and easy target. Escape would be impossible for most super heavy tanks, since they would to slow to move away from the enemy fire.

Today, enemy fire is much more powerful than during WWII. It is easy to imagine how rockets or missiles could destroy a super heavy tank much easier than a group of smaller tanks.

The lack of defenses against air strikes weren't the only problem with the super heavy tanks. The construction of such a monster would require enormous amounts of raw materials - something that was in short supply during WWII and probably used better elsewhere.

Another problem would be the transportation of a super heavy tank. Most of them were too big to be transported by train, so they would have to rely on their own ability to move forward. Problem was that most of them were extremely slow, so they might not reach the battlefield before it was too late.

In addition, the super heavy tanks were often so heavy that they would destroy normal roads. They would therefore have to drive through fields and so on, which meant even slower movement than were possible on normal roads.
