K37s start with the RA-TNTRL-K37 engine, which is really sort of fine.  Your main torch influences your transit reserve, and having a more efficient torch significantly reduces it, letting you spend more propelling eating rocks.  Unfortunately, the only one with better exhaust velocity is the BWM, which has an annoying one second startup time.  The NPMP is really where its at, but that thing expensive. 


the pinch fusion torch works different than everything else. it uses a huge spike of electricity to start, and then no electricity after that. but that'll set off all your warning alarms every time you use it. annoying.

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.
