UAC Defenses

At each colony there is at least 10 Orbital Defense Platforms, which Ceres and eris having the most, at least 150 or so at Ceres, and Eris having 50. There are also orbital shipyards, orbital defense hangers, som of Kevin's defenses also.

At Tribute and New Carthage there is an multi-AI controlled network of 12.7cm point defense guns around cities, bases, coasts, and other locations.

At Mars, there are 12.7cm point defense guns, bunkers for a possible Sith attack, and turrets that are able to be raised out of the ground to defend factories if their locations are compromised.

Each colony has a form of safe bunker, with Tribute, New Carthage, and Viery (Mars) having the main ones incase Earth falls.

Around each colony are warp detection systems (also scattered around the UAC controlled asteroid belt) and warp disruptors.

If there is anything I missed I will add it in

At Tenelapis, there are numerous point defense guns, airbases, and exits to underground bases on the outer crust.

Caelmare has a few 12.7cm point defense guns around the main base
