Israeli Defense Firms Vie for Unmanned Submarine Market

Israeli defense industries are aggressively entering the growing global market for unmanned underwater vehicles (UUVs), driven by increasing demand from navies worldwide for autonomous systems. Elbit Systems announced it will showcase its new capabilities in this sector at the Euronaval 2026 exhibition in Paris, following its acquisition of Canadian firm ISE.

ISE, based near Vancouver, Canada, brings over 50 years of experience in underwater robotics, having developed and produced autonomous and remotely operated underwater vehicles. The company has supplied more than 250 such systems to over 20 countries. While the acquisition's financial scope is not substantial for Elbit, it signifies a strategic push into the unmanned underwater warfare domain.

The newly acquired capabilities include UUVs designed for intelligence gathering, mine detection, anti-submarine warfare, and protecting strategic maritime infrastructure. These autonomous systems can operate without human crews, equipped with various sensors like sonar for seabed scanning, threat identification, and monitoring suspicious activity around ports, underwater cables, and energy infrastructure. Elbit plans to integrate these underwater assets with its existing "Seagull" family of unmanned surface vessels to enable coordinated operations and data sharing.

Elbit Systems is not alone in this field. Israel Aerospace Industries (IAI) has already developed the "Blue Whale" unmanned submarine, which was delivered to the German Navy in February as part of a deal worth tens of millions of dollars. This marked the first autonomous underwater vehicle acquisition by the German Navy. Greece is also reportedly considering leasing three such submarines to bolster its maritime capabilities against Turkey.

The demand for UUVs is escalating due to concerns over potential damage to underwater cables, gas pipelines, and energy infrastructure. These vehicles are crucial for tasks like mine clearance and reconnaissance in dangerous areas, reducing the need to risk human crews. The importance of UUVs has been highlighted by recent events, including a U.S. Navy operation in the Strait of Hormuz involving UUVs for mine clearance and reports of the U.S. Navy expanding contracts for AI to identify Iranian mines. Conversely, the U.S. military has also intercepted and destroyed Houthi UUVs and components in Yemen.
