Sensor Phalanx

The Sensor Phalanx is a long-range sensor array built on a moon. It can spy on fleet movements around planets in neighbouring systems — without sending Espionage Probes.

Each phalanx scan consumes deuterium. The cost depends on the distance to the scanned planet.
Capabilities
- Reveals all incoming and outgoing fleet movements around the target planet
- Shows fleet composition, cargo, speed, arrival time, and mission type
- Cannot be blocked by the target player
- Works through Shield Domes
Experienced players assume they are being phalanxed when flying slow fleets. They either:
- Fly at 100% speed to minimise the window
- Use the Jump Gate to teleport fleets between moons
- Vary fleet-save timings
Tips
A level 3 Phalanx covers 8 systems on each side — enough to monitor most nearby activity. Level 5 (24 systems) covers most practical raiding ranges.
Use your own phalanx to check if an attacker is incoming before your fleet lands. Knowing their timing lets you recall or adjust.
Place a Phalanx and a Jump Gate on the same moon. Spot a target, jump your fleet to the closest moon, launch immediately.
