The SSAK-77 Magnetic Accelerator Cannon, or MAC, is an extremely powerful United Nations Space Command Navy weapon system. It is capable of projecting a six hundred tonne composite round at a high velocity.


The SSAK-77B variant is a larger version of the standard SSAK-77, requiring an oversized external fusion reactor and laser inducer in order to discharge.


The SSAK-79 cannon, often called the Super Magnetic Accelerator Cannon, is a massive weapon capable of projecting at six thousand tonne round at velocities approaching forty percent c.
