Key facts
- The Japan Coast Guard is testing Yanmar's uncrewed gas detection boat, named "Albatross."
- The boat is designed to detect hazardous gases and dangerous substances after maritime accidents.
- Testing will focus on rapid deployment, accuracy of the detection equipment, and remote control system capabilities.
- The Japan Coast Guard has also contracted for two GA-ASI SeaGuardian Remotely Piloted Aircraft (RPA) systems, expected in 2025.
- The SeaGuardian RPAs will be used for maritime surveillance, search and rescue, and disaster response.
The Japan Coast Guard is advancing its capabilities in maritime safety and surveillance through the testing of autonomous vessels and aircraft. Near Yokohama, the service is evaluating Yanmar's uncrewed gas detection boat, named "Albatross," which is designed to safely identify hazardous substances following marine accidents. This initiative aims to reduce risks for human crews and improve the efficiency of detection operations.
The "Albatross" boat measures 3.8 meters in length, 1.9 meters in width, and has a gross tonnage of 0.3 tons, capable of speeds exceeding 5 knots. Testing will encompass rapid deployment from land transport, the precision of its hazardous substance detection equipment, and the functionality of its remote control system. This development is part of a broader effort to enhance maritime safety and response capabilities.
In parallel, the Japan Coast Guard has contracted for two SeaGuardian Remotely Piloted Aircraft (RPA) systems from General Atomics Aeronautical Systems, Inc. (GA-ASI), with deliveries scheduled for 2025. These medium-altitude, long-endurance aircraft can operate for over 24 hours and are equipped with advanced surveillance technology, including maritime surface-search radars and electro-optic/infrared cameras. The SeaGuardians will support missions such as maritime surveillance, search and rescue operations, and disaster response, building on previous successful deployments, including during the Noto Peninsula earthquake and the 2023 G-7 Summit.
