Joint operation eyed of unmanned surveillance aircraft

e Japan Coast Guard and the Maritime Self-Defense Force have begun planning joint operation of an unmanned patrol aircra as early as scal 2023 to enhance maritime surveillance, government sources have said.

With Chinese and Russian vessels active in the seas around Japan, the JCG and MSDF plan to conduct surveillance more e ectively by sharing data obtained from an unmanned aircra that the JCG has begun operating. e joint operation is set to be a pillar of the organizations’ e orts to enhance cooperation with each other.

e aircra to be jointly operated is a SeaGuardian, produced by General Atomics, an American company. e unmanned aircra boasts superior surveillance capabilities, as it is equipped with devices such as nighttime infrared cameras and sensors, and it will be tasked with conducting searches a er maritime accidents and issuing warnings to suspicious ships, among other missions.

e aircra is 11.7 meters long, with a wing span of 24 meters. It is said to be able to y for more than 24 hours at a time, allowing it to navigate at least once around the perimeter of Japan’s exclusive economic zone before landing.

e JCG started operating its SeaGuardian on Oct. 19, using the MSDF’s Hachinohe Air Base in Hachinohe, Aomori Prefecture, for the drone’s home base. e two organizations plan to quickly establish a three-drone system and deploy at least one of the aircra in the Nansei region extending from the southern edge of Kyushu to near Taiwan.

Currently, images received from the aircra are provided to the MSDF a er they have been processed to a certain extent, but such data will be shared in real time from scal 2023.

Once aircra operations have been veri ed, joint operation will begin, with the MSDF carrying out test ights when the drone is not being used by the JCG.

e Self-Defense Forces have introduced Global Hawk unmanned aircra designed mainly to patrol xed targets, but have not started operating the aircra . e SDF does not possess unmanned

aircra to patrol wide swathes of the sea. e MSDF is considering procuring its own SeaGuardian if the joint operation shows positive results.

In the East China Sea, the Chinese military frequently ies unmanned aircra . e Air Self-Defense Force scrambles ghter jets to confront these drones, which are much cheaper to operate, and it has been argued that such a response is not cost-e ective.

Consequently, the SDF plans to explore use of the MSDF’s unmanned

aircra to monitor aircra and vessels in cases where there is low risk of intrusion into Japan’s air space or territorial waters. An idea has also surfaced to station a drone at air base on Tokyo’s Iwoto Island in the village of Ogasawara to enhance surveillance functions for the Paci c Ocean.

Cooperation between the JCG and the MSDF has become a key point in the government’s discussions on how to drastically enhance the nation’s defense capabilities.

In waters around the Senkaku Islands of Okinawa Prefecture, the JCG, as a Japanese law enforcement unit, has been confronting China Coast Guard vessels. However, it is essential to have a system that allows for the MSDF to take over seamlessly if there is an incident that escalates beyond what the JCG can handle. To this end, the government plans to study coordination between the two organizations in emergencies, in addition to promoting general cooperation between the two. (Nov. 8)
