Incredibly impractical, might be possible.
If it's going to be impervious to tank cannon, it's going to need incredibly thick armor, equivalent to better than a meter of steel. Everywhere. As
you might guess, that adds up pretty quick. If you want it to be impervious to even regular sized bombs, it will need to have armor equivalent to
SEVERAL meters of steel. Same if you want it to be protected against powerful IEDs and mines, which are quite adept at killing low, tracked
If it's nuclear powered, it will have to worry about heat dissipation. Nuclear vessels use the ocean for easy cooling. A nuclear tank would require a
huge radiator, which can't be all that well armored, since it needs good airflow. It's weapons will need to be under a degree of armor, since it
will draw fire like nothing else, and if all it's guns get blown off, it's not going to do much.
Such a vehicle will HAVE to be tracked. the ground pressure will be enormous. There's no way it'd be able to float in water, given the thickness of
armor compared to it's size. It would need to drive across the bottoms of rivers.
It should have multiple sets of treads, because it's definitely going to end up losing a few, and you won't be able to put them back on without huge
support vehicles or at a base. I recommend multiple tread pairs on articulated suspension arms, so that it can cross rougher terrain, but the weight
and size might be excessive. Each tread should be powered by one or more individual electric motors, so the overall vehicle can be all-electric.
it will probably carry VLS missiles, but I'm not sure what kind of main gun such a thing should have. Several conventional tank guns would be
cheaper, and would still be capable of killing enemy tanks out to a few kilometers. Custom built huge naval-style guns might be excessive. not that I
have anything against excessive firepower, it's just that you'd not be able to carry as many shells. Railguns might be available by the time someone
would build such a monstrosity, and nuclear power lends itself well for an all-electric vehicle.
It will need anti-aircraft protection, and anti-missile systems, because it's a target large enough to use anti-shipping missiles on. It will take a
ridiculous amount of point defense to be remotely viable.
All told, it's a bad idea. If your enemy gets just five tanks for one of these, he'll just drive around it with his greater mobility and # with all
your support stuff and industry. If you're on the offensive, he'll just lay mines big enough to kill it. Huge piles of high explosives are always
far, far cheaper than huge tanks. As huge as it is, it's movements will be limited by the terrain, and therefore predictable.
Likewise, unless you get to the point where lasers make it impossible to have combat aircraft, it will be a bomb magnet. Bombs and missiles can be
scaled up much easier than tanks can. Point defense is key.
Having many units is always better, because you can perform many tasks at once. A huge tank just lets you flatten things in your line of sight. Your
enemy can easily just note it's position and avoid it. Or they could blow off all it's treads, and leave it. Then you'd have to send another one to
drag it back, because no recovery vehicle save for one built specifically for the task could drag such a huge vehicle. For the cost of a few tanks,
they could effectively divert a large portion of your forces for hours.
