General Atomics Aeronautical Systems, Inc. (GA-ASI) has taken a significant step in the realm of anti-submarine warfare with its MQ-9B SeaGuardian drone. Between January 20 and 30, 2025, the company conducted a series of successful tests where new anti-submarine sensors were deployed, demonstrating that this unmanned platform is capable of effective detection and tracking of submerged targets.
The SeaGuardian’s capabilities in anti-submarine warfare have been expanded through the integration of modules from the Sonobuoy Dispensing System (SDS). These new modules include DIFAR, DICASS, and Bathythermograph sonobuoys, which allow for the collection of acoustic and thermal data. The incorporation of this technology has significantly improved the system’s effectiveness, enabling it to identify and track submarines more accurately.
David R. Alexander, president of GA-ASI, highlighted that these tests mark a “major leap forward in unmanned capabilities,” opening up new possibilities for maritime operations in the undersea domain. This innovation could be key to strengthening defense and monitoring strategies in international waters.
An outstanding aspect of the development of this project has been GA-ASI’s ability to correlate the sonobuoy ejection speed with strain and deformation data. This advancement promises a highly reliable launch model for future operational deployments. Collaboration with the Naval Air Warfare Center Aircraft Division (NAWCAD) AIRWorks has been crucial in overseeing and supporting these development initiatives.
In the face of growing demand for advanced maritime capabilities, GA-ASI expects increased interest in the MQ-9B SeaGuardian, especially since it offers a more cost-effective alternative compared to traditional manned maritime surveillance platforms. This could transform the way underwater monitoring operations are carried out in the future.
