MARLIN Unmanned Marine Vehicle Tested with New Systems

Unveiling Next-Generation Maritime Surveillance: How MARLIN and KATFISH Transform Underwater Threat Detection

In an era where maritime security faces increasingly complex challenges, innovative technologies like the MARLIN Unmanned Marine Vehicle and the KATFISH towed sonar system are redefining underwater threat detection and surveillance. These cutting-edge systems, developed through strategic partnerships such as between ASELSAN and Sefine Shipyard, are setting new standards in autonomous naval operations, offering faster, more accurate identification of underwater hazards such as mines, unmanned underwater vehicles, and critical infrastructure vulnerabilities.

MarLIN and KATFISH: A Synergistic Approach to Underwater Security

MarLIN (Maritime Laser Integrated Network) is an advanced autonomous underwater vehicle (AUV), equipped with state-of-the-art sensors and navigation systems designed to operate seamlessly in complex marine environments. When integrated with KATFISH, a highly modular, towable sonar system developed by Kraken Robotics, the combination creates a powerful underwater reconnaissance platform capable of rapid deployment and high-resolution data collection.

This integration enhances real-time detection and classification capabilities, providing naval operators with critical intelligence faster than traditional, manual surveys. Thanks to the autonomous navigation features of MarLIN and the high-definition sonar imaging of KATFISH, navies can now identify potential threats with unprecedented precision—covering large areas in significantly reduced timeframes.

Operational Highlights from Recent Tests

Recent successful tests off the coast of Istanbul demonstrated how the combined MARLIN and KATFISH systems excel in detecting and classifying underwater objects. During these trials, Kraken’s KATFISH system, with its 3×3 cm resolution at distances of up to 200 meters, transmitted real-time data to command centers via the SEFİNE System Software (SİSAM). This software enables operators to remotely classify targets during ongoing missions, drastically reducing the latency faced with conventional methods.

• Fast Detection: Rapid identification of simulated mine-like objects and underwater structures.
• Real-time Data Transmission: Live high-resolution imaging allows for immediate action.
• Autonomous Navigation: MarLIN’s smart routing enables comprehensive coverage without human intervention.

Bernard Mills, Vice President of Kraken Robotics Defense Group, emphasized the strategic importance: “Integrating KATFISH with MarLIN can vastly improve how navies approach underwater threat detection—making operations more efficient, safer, and more effective.”

Global Deployments and Future Prospects

The UK Royal Navy already piloted these advanced systems in the ARCIMS (Autonomous Riverine and Coastal Infantry Marine System) program during demonstrations near Portland. These tests highlighted the system’s ability to operate at depths up to 300 meters, mapping underwater environments with high precision and relaying data through satellite links for immediate analysis.

Why This Innovation Matters in Modern Naval Warfare

Traditional mine-hunting and underwater reconnaissance operations rely heavily on manual, labor-intensive procedures that often delay critical decisions. With MARLIN and KATFISH, naval forces gain a decisive edge by automating these processes, which translates into:

• Increased operational speed — faster surveys cover more ground than ever before.
• Enhanced safety — reducing human exposure in dangerous environments.
• Higher accuracy — minimizes false positives and ensures precise targeting.
• Adaptability — systems can be quickly reconfigured for diverse missions involving search, rescue, and infrastructure inspection.

Step-by-Step: How These Systems Improve Maritime Security

1. Deployment: Autonomous underwater vehicles (like MarLIN) are launched from ships or shore stations.
2. Navigation: Through AI-powered algorithms, the AUVs navigate complex terrains, avoiding obstacles autonomously.
3. Data Collection: High-resolution sonars like KATFISH scan the seabed, identifying anomalies with exceptional detail.
4. Data Transmission: Real-time, encrypted data streams relay images and classifications directly to command centers.
5. Analysis and Response: Operators interpret the data swiftly, initiating countermeasures or further investigation as needed.

Conclusion

The integration of MARLIN and KATFISH marks a pivotal advancement in maritime defense technology, providing navies worldwide with sophisticated tools to detect and neutralize underwater threats efficiently. As these systems mature, expect broader deployment across allied navies, enhancing global maritime security and demonstrating the transformative power of autonomous underwater systems in modern warfare.
