Variant 1 ships are equipped with a forward magnetic accelerator cannon and 374 Proton Cannons, which were replaced in later variants, as well as several other armaments which survived future upgrades. Variant 1 ships were constructed until early 11 NE by Kira's Kingdom, and until early 12 NE by the New Kingdom Alliance.
In early 11 NE, the Mars-Class was upgraded to Variant 2, with the most notable changes being the replacement of the forward MAC with a high-mass Neutron Cannon, the replacement of the Proton Cannons with more effective Neutron Cannons, and the replacement of the fusion reactor with a Metatron Reactor. Variant 2 ships were constructed until mid 12 NE.
Variant 3 added several newly-developed technologies, including the multi-purpose Spacetime Manipulation System and the Morris-Thorne Drive. Variant 3 is the current production model, and all remaining Variant 1 & 2 ships are in the process of being upgraded to Variant 3 standards.
