Gabler Unveils Submarine-Launched Uncrewed Surface Vessels at DWT 2025

At the 27th DWT Naval Workshop in Dobbin-Linstow, Germany, Gabler, a renowned German defense company specializing in submarine technologies, introduced its innovative uncrewed surface vessels (USVs) designed for torpedo tube launch (TTL). This announcement marks a significant advancement in naval autonomy and stealth operations.

Strategic Collaboration with FLANQ

Gabler has partnered with FLANQ, a European leader in autonomous maritime platforms, to co-develop these cutting-edge USVs. The collaboration aims to deliver versatile, cost-effective platforms for Intelligence, Surveillance, and Reconnaissance (ISR) missions, as well as single-use tactical operations. This partnership ensures the integration of advanced technologies and rapid development timelines, meeting the operational needs of European and NATO naval forces.

Key Features of the USVs

The newly unveiled USVs, named Ranger and Raider, share a common design optimized for TTL deployment:

• Dimensions and Build: Both vessels are approximately 4.5 meters in length, with a hull rated for depths up to 300 meters. They feature a folding mast and keel, allowing for compact storage and stealthy deployment from standard submarine torpedo tubes.

• Power and Payload: Equipped with electric drivetrains, both models offer multiple payload bays to accommodate various mission-specific equipment.

Ranger: Reusable ISR Platform

The Ranger is designed for extended ISR missions. It is equipped with a comprehensive sensor suite that provides real-time surveillance and reconnaissance capabilities. This allows submarines to deploy and recover the USV discreetly, maintaining stealth and operational advantage in contested waters. The reusable nature of the Ranger enhances operational flexibility and cost-effectiveness.

Raider: Single-Use Tactical Strike

The Raider is tailored for single-use tactical missions. It carries a user-supplied effector payload in its forward compartment, enabling naval forces to neutralize high-value targets without exposing themselves to direct threats. The expendable design of the Raider makes it ideal for precision strikes in high-risk environments.

Enhanced Operational Capabilities

Both USVs are fully compatible with standard submarine torpedo tubes, facilitating covert deployment without the need for diver assistance. This capability is crucial for operations in denied, contested, or high-threat environments where traditional surface or aerial naval assets may be compromised. The integration of these USVs into naval operations enhances situational awareness and extends the reach of submarines, providing a significant strategic advantage.

Forward-Looking Developments

The partnership between Gabler and FLANQ reflects a broader strategic shift toward uncrewed-first capabilities in naval warfare. By enabling submarines to deploy low-cost, mass-producible USVs for a wide range of missions—from littoral surveillance to deep-sea reconnaissance—this initiative delivers domain advantage without compromising stealth. The development of these USVs underscores the commitment to strengthening European and allied undersea defense capabilities at pace and cost.

As naval threats evolve and maritime zones become more complex, the introduction of submarine-launched USVs represents a significant leap forward in naval autonomy and operational flexibility. The Ranger and Raider platforms are poised to play a pivotal role in shaping the future of naval operations, providing unmatched versatility in complex and contested environments.

The unveiling of these USVs at DWT 2025 highlights the ongoing advancements in naval technology and the increasing emphasis on autonomous systems in modern warfare. With continued development and integration, these platforms are set to enhance the capabilities of European and NATO naval forces, ensuring they remain at the forefront of maritime defense.
