Clans

Clan defence support

Send your ships to defend a clanmate without giving them away. Learn support capacity, research, recall and the host’s Dominion calculation.

How it works

The host must enable Accept clan support. Your ships stay yours and use the host’s separate support area, equal to that planet’s Hangar capacity. Until home, they also occupy your own Hangar room and a flight bay.

Support fights alongside the host using its own research. A supported planet cannot tactically retreat. If a support fleet does not meet the attack’s tier conditions, it may return without entering combat when the raid arrives.

The sender can recall support in transit or while stationed. The host can send it home; disabling support also returns stationed fleets. Both legs’ fuel is paid at launch and not refunded by recall. The stay has a maximum duration and can end earlier near season close.

Your next decision

Support protects the planet but puts allied ships at risk. Only the host’s Dominion changes on the defending side; supporters do not receive their own score change from that defence.

The combined armed-unit value relative to the host’s own value sets a capped score factor. It increases the host’s loss exposure and reduces gain for the host’s own exchange. Permanent support losses enter separately at resource value. Joint-attacker counts also affect the result, so use the report’s final calculation.
