Space Fleet Expansion

Space Fleet Expansion is a progression item that increases the number of space combat ships Icarus can operate. It is tied to the Corvette stage of space combat and improves Icarus’s fleet capacity in two different ways depending on the level: some levels add more slots to a single fleet, while later levels add more fleets instead.

The effect changes by level:

• Initial state: 4 fleet slots, 1 fleet, 4 total slots, available when Corvette is unlocked
• Level 1: fleet slots increase by 4, for a total of 8
• Level 2: fleet slots increase by 4, for a total of 12
• Level 3: fleet count increases by 1, for a total of 2 fleets and 24 total slots
• Level 4: fleet count increases by 1, for a total of 3 fleets and 36 total slots
• Level 5: fleet count increases by 1, for a total of 4 fleets and 48 total slots
• Level 6: fleet count increases by 2, for a total of 6 fleets and 72 total slots
• Level 7: fleet count increases by 2, for a total of 8 fleets and 96 total slots

Because the upgrade alternates between expanding a fleet’s internal slot count and increasing the number of fleets, its value depends on how you want to organize your space forces. Early levels are best for making one fleet stronger, while later levels scale overall capacity more aggressively by letting Icarus command more fleets at once.

In practice, this means Space Fleet Expansion is one of the core enablers of larger space combat deployments. If you are trying to field a single concentrated strike force, the early slot-increase levels are especially useful. If you are building a broader multi-fleet setup, the later levels provide the larger jump in total capacity.
