Service is 0.1% of the total value of the fleet in metal and minerals. They are written off evenly within a day from all colonies and asteroids in proportion to their production level. If the amortization exceeds production, the amortization accumulates.
Fleet costs are calculated at the time the statistics are updated, taking into account the player's entire fleet: in flight, on planets, asteroids, etc., except for special production units, which support themselves (Metal Harvester, Mineral Harvester, Gas Harvester, Planetoid, Red Droid, Blue Droid, Green Droid, Distiller, Planetary Ripper). Amortization is not assigned up to 25 000 points.
Amortization can be reduced by hiring an officer Emperor, elder Psionicist, mutants Mantrid, Chuchkhe, and Warden.
