General Atomics Pushes Unmanned Sub-Hunting Forward with Successful MQ-9B SeaGuardian Test

General Atomics Aeronautical Systems, Inc. (GA-ASI) has taken a significant step in anti-submarine warfare (ASW) by successfully testing advanced air-dropped sonar technology on its MQ-9B SeaGuardian. In a groundbreaking series of tests conducted from January 20-30, 2025, the unmanned aerial vehicle (UAV) demonstrated its ability to deploy and operate cutting-edge sonobuoys, solidifying its role as a cost-effective alternative to traditional manned ASW platforms.

This latest achievement involved the MQ-9B deploying pre-production Sonobuoy Dispensing System (SDS) pods, allowing the UAV to track and analyze submerged targets with high precision. Using Directional Frequency Analysis and Recording (DIFAR), Directional Command Activated Sonobuoy System (DICASS), and Bathythermograph sonobuoys, the SeaGuardian was able to gather critical underwater intelligence while performing real-time acoustic data processing.

GA-ASI President David R. Alexander highlighted the test as a major milestone, emphasizing that it proves unmanned aircraft can conduct persistent ASW operations. He noted that the successful deployment of the SDS pods opens new possibilities for the MQ-9B SeaGuardian’s future role in distributed maritime operations.

The Naval Air Warfare Center Aircraft Division (NAWCAD) AIRWorks played a vital role in overseeing the development of this capability. This collaboration builds upon GA-ASI’s previous ASW demonstrations, including the Rim of the Pacific (RIMPAC) exercise in July 2024, where the MQ-9B first showcased its potential in naval operations.

By integrating high-end ASW capabilities into the MQ-9B at a lower cost than conventional manned systems, GA-ASI is positioning the SeaGuardian as a game-changer for naval forces worldwide. The success of these tests is expected to drive further interest from military customers looking to enhance their maritime surveillance and undersea warfare capabilities.
