Reactor fuel

Early accessCitadel is still in development. Numbers and rules on this page can change between patches. Last checked October 2026.

Reactor fuel is the clock on a run. Every hull carries 1,800 units and burns one a second, which is 30 minutes.

• Fuel burns only in a Breach. It does not burn in a hub or in the tutorial.
• At zero the ship starts taking damage: 1 a second at first, rising by 0.55 a second for every second it stays empty.
• Fuel refills for free while the ship is tethered to the pad's refit terminal in a hub. A full refill takes 12.5 seconds.
• Fuel does not depend on the fit. No module changes it.
