Defensive and economy-support ships that keep a fleet alive longer.
Expansion supports a durable, sustainable fleet. Its unlocks help you absorb damage and amplify your other ships rather than dealing the damage themselves.
| Tier | Unlocks |
|---|---|
| Tier 2 | Shield Bearer (tanky medium warship) |
| Tier 3 | Energy Relay (support — damage boost) |
A few Expansion nodes go a long way for survivability. Shield Bearers let your fragile damage dealers live longer, and an Energy Relay raises your whole fleet's output. Good complement to a Domination-heavy military path.
Ten branches, 65 nodes. Research unlocks advanced warships and structures.
The primary military branch — unlocks most warships and the Fleet Hangar level-5 upgrade.
Advanced and elite warships, including the endgame Ascendant.
The branches behind support craft, disruption, and siege/elite weapons.
