The Japan Maritime Self-Defense Force (JMSDF) has taken a decisive step into the future of maritime defence, selecting General Atomics Aeronautical Systems, Inc.’s (GA-ASI) SeaGuardian Remotely Piloted Aircraft (RPA) systems for its Long Endurance Unmanned Aerial Vehicle program. The selection, announced in December 2024, follows over 1.5 years of rigorous testing and evaluation by the JMSDF. The service began its trial operation project with the SeaGuardian in April 2023, putting the system through its paces to assess its suitability for Japan’s challenging maritime environment. This move mirrors a similar decision by the Japan Coast Guard (JCG). On Aug. 15, the JCG signed a contract for the purchase of two SeaGuardian RPAs from GA-ASI, with delivery expected in 2025. This follows the JCG’s ongoing Company-Owned, Contractor-Operated agreement with GA-ASI, which began in April 2022 and has seen SeaGuardians actively supporting a range of JCG missions.
The SeaGuardian is no ordinary drone. This Medium-altitude, Long-endurance (MALE) RPA system boasts an impressive capability to remain aloft for over 24 hours, depending on its configuration. But it’s the system’s sophisticated sensor package that truly sets it apart. The SeaGuardian is equipped with two cutting-edge multi-mode maritime surface-search radars, each featuring Inverse Synthetic Aperture Radar (ISAR) imaging, allowing for detailed target identification. An Automatic Identification System (AIS) receiver further enhances its ability to track and classify vessels, while a high-definition full-motion video sensor with optical and infrared cameras provides persistent surveillance capabilities, day and night. Rounding out the sensor suite are electronic intelligence receivers, enabling the SeaGuardian to gather critical signals intelligence data. This potent combination of sensors enables the SeaGuardian to detect, identify, and track surface vessels across thousands of square nautical miles in real-time.
The JMSDF’s trial operation project was designed to rigorously assess the SeaGuardian’s capabilities and determine its potential role in Japan’s maritime defence strategy. A key objective was to evaluate the system’s adaptability to manned-unmanned teaming concepts, a critical aspect of modern naval operations. The trials also focused on the SeaGuardian’s ability to reduce manpower requirements, potentially freeing up personnel for other critical tasks. Critically, the JMSDF tested the SeaGuardian’s ability to perform missions traditionally conducted by manned aircraft, demonstrating the system’s potential to act as a true force multiplier. Data collected during these trials was shared with the Japan Coast Guard, highlighting the interoperability and potential for collaboration between the two agencies. The JMSDF’s decision to formally select the SeaGuardian after this comprehensive trial period underscores the system’s proven capabilities and its potential to reshape Japan’s maritime security posture.
This rigorous testing is further bolstered by the JCG’s real-world experience with the SeaGuardian system. The JCG has deployed SeaGuardians in a variety of missions, including search and rescue, disaster response, and maritime surveillance. Notably, the system has proven its effectiveness during high-profile events such as the 7.6 magnitude earthquake near the Noto Peninsula of Ishikawa Prefecture and the 2023 G-7 Summit in Hiroshima. This combination of rigorous trials and successful real-world deployments highlights the SeaGuardian’s value as a robust and versatile asset for maritime security.
GA-ASI has further bolstered Japan’s maritime domain awareness by providing its Optix+ software suite. Optix+ serves as the brains behind the SeaGuardian’s operations, gathering a wealth of information from various sources, including the RPA’s onboard sensors. This data is then fused and presented to operators in a comprehensive and intuitive display, providing a clear and actionable picture of the maritime environment. Optix+ facilitates real-time intelligence, surveillance, and reconnaissance (ISR) data sharing, enabling seamless coordination between different units and agencies. Perhaps most importantly, Optix+ automatically correlates data from multiple sources, allowing for the rapid detection of anomalous activities at sea. This capability is crucial in a region facing a range of maritime security challenges.
The JMSDF’s selection of the SeaGuardian is a watershed moment for Japan’s maritime defence. It represents a significant investment in unmanned systems and signifies a commitment to leveraging cutting-edge technology to enhance maritime security. This move not only provides the JMSDF with a powerful new tool for maritime surveillance but also paves the way for greater integration of unmanned systems across Japan’s defence forces. Coupled with the JCG’s commitment to the SeaGuardian system, Japan is clearly positioning itself at the forefront of unmanned maritime capabilities in the region.
