Fleet Movement

Fleet movement is instant — a single transaction with no transit time. The fleet’s location updates immediately.
Fleet moves with player between planets
Exploration: new planet created, fleet moves to new planet, old planet released
One planet ownership at a time
Planet completion: When a planet’s ore depletes, all fleets are automatically sent away (peace deal)
Fleet movement validation does not block moves based on fleet-away state
Fleets can move to already-populated planets

Fleet Return Conditions

Fleets stay “away” until one of these triggers:

Explicit move — The player issues fleet-move to return home
Command Ship destroyed — If the fleet’s Command Ship is destroyed, the fleet auto-returns
Planet completed — If the defending planet’s owner depletes all ore and explores a new planet, visiting fleets are sent away

Fleets do not auto-return on a timer. For raids, you have until one of the above triggers to complete the raid PoW and submit planet-raid-complete.
