TL;DR
Kawasaki Heavy Industries is partnering with Airbus to develop anti-submarine drones for Japan. The project will retrofit Airbus’s Eurodrone with Kawasaki’s maritime surveillance systems. The development aims to enhance Japan’s naval capabilities.
Kawasaki Heavy Industries and Airbus have announced a partnership to develop anti-submarine drones intended for Japan’s defense forces. The collaboration will focus on outfitting Airbus’s Eurodrone with Kawasaki’s maritime surveillance and anti-submarine systems. This initiative marks a significant step in Japan’s efforts to modernize its naval capabilities and enhance maritime security.
The partnership was revealed on June 26, 2026, with Kawasaki agreeing to supply anti-submarine technology to Airbus for integration into the Eurodrone platform. The modified Eurodrone will be equipped with Kawasaki’s maritime surveillance systems, designed to detect and track submarines in Japan’s surrounding waters. The project aims to develop operational prototypes that can be proposed to Japan’s defense ministry for future deployment.
According to officials from Kawasaki and Airbus, the collaboration leverages Kawasaki’s expertise in maritime systems and Airbus’s experience in drone and aerospace technology. The project is part of Japan’s broader strategy to bolster its undersea defense capabilities amid regional tensions and increasing submarine activity by neighboring countries.
This collaboration signifies Japan’s focus on advancing its maritime surveillance and anti-submarine warfare capabilities amid regional security challenges. The development of dedicated anti-submarine drones could provide Japan with more flexible, rapid-response assets to monitor and counter submarine threats, which are increasingly sophisticated. The partnership also highlights ongoing international cooperation in defense technology, with potential export implications for the region.

Japan’s Growing Need for Advanced Undersea Warfare Tools
Japan has been seeking to modernize its naval forces in response to regional tensions, particularly with China and North Korea. Historically reliant on traditional submarines and surface ships, Japan is now exploring drone technology as a force multiplier. The Eurodrone, developed by Airbus, is a long-range, intelligence-gathering UAV used by European countries. Kawasaki’s involvement marks a move to adapt this platform for maritime surveillance and anti-submarine roles, reflecting Japan’s strategic priorities since increasing submarine incursments in the region.
The partnership builds on existing efforts by Japan and its allies to develop unmanned systems capable of operating in contested environments, filling gaps in surveillance and reconnaissance capabilities. The project also aligns with Japan’s recent defense policy updates emphasizing technological innovation and regional security cooperation.
“This collaboration will enhance Japan’s maritime domain awareness and provide a new tool for anti-submarine warfare.”
