Active sensors improve detection but reveal the emitting ship's location. That tradeoff changes when the sensor platform is uncrewed and can operate away from the convoy it protects. A radar or sonar emitter placed off-axis could complicate an enemy's approach, draw attention, and extend the defended area even if the platform itself becomes a target.

An uncrewed escort positioned away from a convoy could radiate radar or active sonar and force an opponent to react without exposing sailors.
