The MQ-9B SeaGuardian has taken another step forward in its evolution for anti-submarine warfare missions after being showcased with four sonobuoy launch pods during CANSEC 2026 in Canada.
The new configuration represents a significant expansion of the unmanned aircraft’s capabilities, which had previously been seen operating with only two pods. In addition, the drone was also equipped with a central maritime radar pod, further enhancing its naval surveillance capabilities.
With four SDS pods installed, the SeaGuardian can carry up to 40 standard U.S. Navy sonobuoys or 80 units of the smaller model, significantly increasing its ability to detect and track submarines. The platform has already conducted tests with various types of sonobuoys, including active and passive systems as well as advanced underwater sensors, making it one of the leading contenders for unmanned anti-submarine operations.
General Atomics highlights that the combination of sonobuoy launchers and the onboard monitoring and control system enables continuous surveillance of strategic maritime areas. The company states that the aircraft can track submerged targets for extended periods while maintaining full maritime situational awareness, reducing operational costs and risks to human crews.
The advancement comes alongside the expansion of the MQ-9B’s role into airborne early warning missions following tests conducted in partnership with Saab. Despite losses recorded in high-intensity combat environments, U.S. military officials continue to emphasize the platform’s strategic value. Operating alongside P-8A Poseidon aircraft and MH-60R helicopters, the SeaGuardian can expand submarine search coverage and free manned assets for other operational tasks.
