Japan to Deploy Underwater Drones for Submarine Detection

Japan plans to introduce a fleet of autonomous underwater drones equipped with advanced sonar and detection systems to enhance its ability to monitor submarine movements across key maritime zones, according to defence officials. The deployment represents a significant upgrade to the country's undersea surveillance infrastructure amid rising strategic tensions in the region.

The underwater unmanned vehicles would operate in Japanese territorial waters and exclusive economic zones, providing real-time intelligence on foreign submarine activities. Defence planners say the technology will improve detection capabilities while reducing the operational burden on manned naval assets currently tasked with submarine surveillance missions.

The move comes as Japan faces increasing scrutiny over Chinese and Russian submarine operations near its coastlines. Tokyo has repeatedly expressed alarm over unidentified submarines transiting through the Tsushima Strait and other strategic waterways, citing security concerns that have prompted expanded naval patrols and enhanced monitoring systems.

Japanese defence officials indicate the drone programme will be integrated into the country's broader maritime security strategy, complementing existing naval vessels and aircraft. The initiative is expected to enhance situational awareness while contributing to regional stability through improved transparency of undersea activities.
