[Full tile operational perimeters redacted]


Unit sensor systems
Primary sensor set:
Full range standard video; thermal imaging; electromagnetic imaging. All primary sensors are mounted in stereoscopic configuration and providing zoom functionality, allowing range calculations without external equipment.
Weapon sighting optics:
Stereoscopic standard video and thermal imaging zoom capable independent sighting units mounted to primary and secondary weapons.
Body sensors:

If I'm reading it right, this tank's main gun is a 170mm Coil-assisted Rocket launcher.  It needs more venting system along the length, probably some cooling vanes (like the things on a computer processor) to dump the waste heat from the rocket, as well as vent the fumes.
Also, the turret rotation should be more limited.  Even accounting for the rocket carrying most of the weight of the shell, the recoil on this thing is going to be immense (A 105mm M1A1 main cannon can kick the 65 ton tank up on its rear tracks.  At 75 tons, the recoil will flip this tank over).

Coming from an engineering student (and serious geek), I think the tank could use some more armor to weigh down the front, and along with the barrel venting, a recoil suppression system would be useful.

Stylistically though, it is a beautiful tank.

Thanks for taking the time to leave some critique, I highly value the input.
The main gun is indeed a hybrid coilgun with a self-propelled projectile. The projectile itself, however has a fused ignition for its propulsion unit, which causes it to fire after it has cleared the end of the barrel. The design provides the majority of initial force through the coilgun, while the projectile's propulsion system is intended to flatten its ballistic trajectory in flight.
While the recoil of the main gun would indeed be titanic, the vehicle is designed with several factors to help mitigate and withstand it. The barrel of the cannon itself is fitted with sealed mercury filled chambers, which help absorb the initial recoil of firing. As well as this, the tank's body and suspension aid in withstanding each firing, as the adaptive suspension system can adjust the tension and ride height of the track base in preparation for firing, as well as the low profile of the vehicle's hull, which lowers the axis of motion on which the gun recoils.
The recoil would still be quite intense, even with such measures, and firing the gun with the turret at a 90 degree angle to the body could very well lift the body on that side off the ground, if not fully overturn the vehicle. The turret rotation is a full 360 degrees due to the fact that the vehicle is controlled by an A.I. system, as opposed to a fallible human operating team who could cause the vehicle to overturn in the heat of battle.

As to weight distribution, the vehicle does rest more heavily on its front than a traditional tank, as the area which would normally contain the driver's compartment and open crew area in lower section of the turret ring are instead filled with the unit's central computation core (turret ring) and systems power generator (hull area forward of turret ring.) 

I'm glad that you liked the visual design, as I am still working on the project, and will be uploading an updated version in the near(ish?) future with a range of visual updates.

Being a Robotics nut IRL, I have to add then, I love this tank.

I also like that you actually considered how heavy things like the AI core would be, and what that would do to the weight distribution.

I'm happy to see that my technical involvement with my projects isn't entirely in vain. I too have a great love for robotics and robotics related technologies, which I feel has very much carried over to my work.

Also, the central processing unit wouldn't be very heavy, compared to the rest of the systems. The onboard processing system is actually fairly basic, as the vehicle is designed to be operated by a remote A.I. core, thus making the vehicle itself more easily disposable in a tactical situation. The Auxiliary Power Unit (APU) would be where the majority of the front weight would be, given that it is a single unit identical to the two main drive engines, but used to produce power exclusively for the electromagnetically driven weapons and other electrically powered systems of the vehicle.

So a land based ROV.  They actually do that on mine-plow vehicles already.  Normal tank crews can fit in there too, but if your is entirely robot operated, it would be unnecessary to include a crew compartment.

Out of curiosity though, where is it driven from then?

The ATLAS is designed as a heavy infantry support unit in an orbitally deployed military operations structure. The idea is that mechanized infantry and armor units are dropped from orbit via dropships and landed directly in or near the targeted combat zone. The actual controlling unit for the ATLAS would remain in orbit, out of harm's way, connected to the vehicle via a quantum entanglement transceiver system.
The actual control unit itself is referred to as an Independent Virtual Entity (IVE), and consists of a self-aware core linked to a large network of quantum bit processor number engines, which allow a single IVE unit to command hundreds, if not thousands, of units on the battlefield (infantry or armor.)
The military system into which the ATLAS fits is intended to be a rapid-deployment strike force, overwhelming enemy forces with massive waves of perfectly coordinated unmanned units.

I suppose it would count as a UGV, by modern terminology.

Do you have signal bounce UAVs in the line somewhere?  Otherwise the signal's going to get scrambled on its way down from orbit.  Same reason modern UAV and UGVs operated from home-base ping off EWACS equipped aircraft.

The IVE would have to be fairly large to control hundreds of units, even accounting for compacting the components.  Probably around the size of two or three UAV control modules today (about 3 40ft ISO containers), if not larger.  It would have to stay spacebourne, as landing the modules, plus the transmitters, would be insanely costly, and difficult.

The communications are handled via quantum entanglement. If you're not familiar with the theory (it's pretty popular in contemporary sci-fi, as well as being a theoretically possible system), it is basically the process of entangling two quantum bits in such a way that when one is affected the other also reacts, regardless of its position in space relative to its twin. At least that's what I understand; quantum mechanics are insane.

The actual IVE core itself is roughly 200 feet across, and is built into its host ship (generally in the most armored/well protected section.) The IVEs themselves are networked throughout the fleet, as well as to other secure locations, allowing them to transfer into any core and operate the systems linked to it.

The actual fleet in which these units operate is designed to be a nomadic, independant state, entirely unconnected with a home-planet and able to gather and process natural resources quickly.
All of these units and systems fit into my original science fiction universe, which is a pretty far-forward fiction focused on a large, varied environment full of a great number of different races and species.
