The Sensor Phalanx, only buildable on a moon, is one of the most useful buildings in the game. Using the Phalanx you can scan a planet for 5,000 deuterium. Fleets in flight towards the planet will be shown, together with their composition of ships and time of arrival (note that you don't see resources that fleets are carrying). This allows a player to send their fleet on an attack that is timed to arrive a few seconds after the target fleet gets back, leaving not enough time for it to be saved again. Note that moons cannot be scanned with a Sensor Phalanx due to their lack of atmosphere.
Sensor Phalanxes are also useful when attacking another player. When attacking another player, the person being attacked can see the attacking fleet coming in. Often, the person being attacked will "ninja" the attacker: move a sizable fleet to the target so that it arrives seconds before the attacking fleet, destroying it, and turning the attacker's fleet into debris. A Sensor Phalanx can be used by the attacker to see if the target is moving a fleet in an attempt to "ninja" the attacking fleet, and the attacker can then decide to call off the attack if need be.
Before moving your fleet to a new area, it is important to be aware of nearby moons. You can find out the ranges of other phalanxes by probing their moons. It should be noted that when another player sensor phalanxes you, there is no in-game message or any message at all notifying you. The only way you could tell that you have been sensor phalanxed is if you see an attacking fleet coming at you within seconds of your own fleet's return. Sensor phalanxes give information on the fleet's origin, size, where it is heading, how long it will take to get there, and when it will get back. If you only see a fleet that has already completed its mission, you won't be able to see the composition of the fleet. In this sense, it is possible to avoid sensor phalanxes by stationing your fleet on a moon, and then fleetsaving from the moon (e.g., to a debris field). As stated above, moons cannot be scanned; therefore, if a player has at least two moons, a fleetsave from one moon to another moon is the safest possible fleetsave and cannot be detected in any way.
After the Lifeforms update, the Sensor Phalanx can now see the speed of the slowest ship in each fleet.

What a Sensor Phalanx Can See[]
If you scan the target planet of the fleet
- Attacking fleets (ACS too)
- Trading fleets
- Fleets on deployment mission
- Spying fleets
- Fleets with the mission hold (ACS)
If you scan the home planet of the fleet
- Fleets coming home from any mission (except Recalled deployment)
- Fleets on a hold or expedition mission
What a Sensor Phalanx Cannot See[]
If you scan the target planet:
- Fleets heading to the planet's DF from moon
- Fleets heading to the planet's moon
- Harvesting fleets launched from or returning to a moon
- Deployment missions from a planet to another planet THAT HAVE BEEN RECALLED
- (Note: This is the only fleetsaving method from a planet without a moon that cannot be seen, but it has to be recalled before reaching the target before it drops off from the Phalanx scan)
In short, you will see when a fleet is arriving at the target planet, whether that fleet is deployed to the target, attacking the target, or some mission from the target that will return the fleet to the target. The key is that a fleet will be making a stop at the target planet, whether it is the target of a mission or the origin of a round trip mission.
Range Formula[]
Phalanx range
This range is the number of Solar Systems on both sides of your moon's coordinates that can be scanned.
(Note : With level 1 sensor phalanx, only the solar system containing the moon with the sensor on it can be scanned.)
