War Eligibility of a corporation or alliance determines the ability of a corporation or alliance to be involved in formal wars. If a corporation or alliance is war eligible it will be able to declare wars, have wars declared against it, and join existing wars as an ally of the defender. If a corporation or alliance is not war eligible, it will not be able to declare wars or have a war declared against it.
The current status of a corporation's War Eligibility can be verified within the Attributes tab of the corporations information window.
As soon as a corporation owns a structure, the corporation becomes eligible for wars.
The following player owned structures will count towards War Eligibility:
- All Upwell Structures (including Upwell FLEX structures)
- Starbase Control Towers
- Player-owned Customs Offices and their Gantries
- Sovereignty Structures of any kind (such as Infrastructure Hubs and Territorial Control Units)
Alliances become War Eligible as soon as one member corporation owns any of the above structures, and as usual, all member corporations of the alliance will be involved in any war the alliance gets embroiled with.
Losing War Eligibility during active wars
If either the attacker or defender of an existing war loses their war eligibility due to their final structure having been destroyed, unanchored (by completing decommission) or transferred off to new owners (where possible), the war will end 24 hours later. If one side of a war loses their last structure during the 24-hour warm up period before a new war allows legal combat, the war will end 24 hours after the end of the warm up period (so combat will be legal for 24 hours total).
The only exception to this is if a war was declared mutual. In that case, it will continue even if one or both sides lose their structures in space as long as the war remains mutual.
