Saab has confirmed development of a large uncrewed underwater drone, reinforcing the defense sector’s shift toward autonomy in naval operations. The vehicle is envisioned as a modular, endurance-focused system, capable of conducting multiple mission types from intelligence gathering to anti-submarine warfare support. Saab’s engineers are prioritizing flexibility, allowing the platform to integrate new payloads such as advanced sonar, surveillance sensors, or communication relays. A major driver behind the initiative is the growing vulnerability of undersea infrastructure, particularly internet cables and energy pipelines, which adversaries have increasingly targeted. NATO has placed significant emphasis on strengthening protection in this area, with Saab’s project aligning closely with alliance priorities. The drone’s development also comes as Sweden enhances its NATO role, highlighting its contribution to collective defense. Industry experts see the program as a step toward enabling persistent maritime surveillance at reduced costs compared to submarines. Saab has not disclosed exact specifications but has signaled a focus on stealth and operating depth. Analysts believe this system will allow navies to monitor contested waters continuously and discreetly, ensuring better detection of hostile activity. Saab’s move cements its role as a leading European innovator in uncrewed maritime technologies, signaling that large underwater drones will be indispensable for the future balance of naval power.
