Swedish defense group Saab has begun developing a new large underwater drone, part of a growing focus on uncrewed maritime systems. The drone is intended to enhance undersea surveillance, reconnaissance, and potentially anti-submarine operations for naval forces. Saab officials describe it as a modular, long-endurance system designed to operate autonomously in deep waters for extended periods. It will be capable of carrying diverse payloads, including sonar packages, surveillance equipment, or electronic warfare systems, depending on mission needs. The drone’s design focuses on stealth, endurance, and adaptability, with features allowing navies to tailor capabilities without requiring entirely new platforms. Saab highlights that such vehicles will be vital in monitoring undersea infrastructure, such as pipelines and communication cables, increasingly vulnerable to sabotage and espionage. NATO and partner nations have been investing in similar platforms, reflecting the recognition that undersea dominance extends beyond traditional submarines. Saab’s initiative complements Sweden’s naval modernization and integration into NATO. Analysts point out that as nations compete for control of critical sea lanes, large drones can fill capability gaps by performing persistent monitoring at a lower cost than manned submarines. Saab has not disclosed specific performance metrics, but industry observers expect the drone to match or exceed existing platforms in range, endurance, and modularity. The project places Saab among key players advancing Europe’s underwater autonomy sector.
