General Atomics Aeronautical Systems tested its 'MQ-9B SeaGuardian' maritime patrol drone, featuring the new Expanded Sonobuoy Dispensing System (ESDS) designed to drop and deploy sonobuoys for anti-submarine operations.
The rollout was demonstrated in recent flight tests and introduced ESDS as a payload enhancement for long-endurance unmanned patrols. The ESDS pod doubles sonobuoy payload compared with previous configurations and enables deployment of Multi-static Active Coherent (MAC) sonobuoys, which coordinate active sonar pings across multiple sensors. The configuration increased the SeaGuardian’s capacity to sustain deep-ocean search patterns and to create wider temporary sensor networks.
For naval operators, the SeaGuardian with ESDS extends persistent ASW coverage without adding crewed flight hours, improving area surveillance and response. This capability reflects a trend toward using long-endurance unmanned platforms to assume routine maritime monitoring tasks.
