Expedition slots determine how many expedition missions you can run at the same time. Inter-War calculates them separately from normal fleet slots.
How does it work?
The formula is max(1, Expedition Technology + Commander bonus + exploration-resort bonus). Commander adds +1 expedition slot and the relevant resort can increase the result further.
Key rule
An expedition slot does not replace a normal fleet slot—the mission still uses the normal dispatch system and must also fit within the overall active-fleet limit.
Practical meaning
If you run expeditions frequently, improving Expedition Technology and keeping the relevant bonuses active increases the number of simultaneous expeditions.
How should you use this in practice?
The “How many expedition slots do I have and what determines them” mechanic is best evaluated on your actual account rather than in isolation. Before making a decision, check the current technology, building or Officer level, active bonuses and the state of the relevant planet or fleet. The server resolves the action from the real game state at execution time.
Common mistake
A common mistake with “How many expedition slots do I have and what determines them” is focusing on only one number. The final result can also depend on other technologies, bonuses, limits, queues or fleet composition. For a major investment or mission, compare the result after changing one factor first, then scale the decision once you know what actually changes.
