The main propulsion engines of a spacecraft usually operate in two modes:

  • Interlunar mode, providing high propellant economy for the extended burns during interlunar travel, serving both as propulsion and artificial gravity.
  • RCS support mode, sacrificing efficiency to provide high thrust for in-ring operations.

The Z-Axial Pinch Fusion Torch (ZAP Drive) works differently than the other engines. When firing, it requires 150 MJ of power to ignite but is self-sufficient once fusion has started. Extended capacitor arrays are recommended to prevent overdraw. Fusion fuel lasts for 30 minutes of thrust and can only be viewed using the EIME HUD.
