Subsea and Seabed Warefare

Advanced Subsea Capabiliti​es for Seabed Warfare and Infrastructure Protection​ ​

Subsea and Seabed Warfare (SSW) is a critical mission area focused on monitoring, protecting, and controlling activity on and near the ocean floor. As undersea cables, pipelines, sensor networks, and other seabed infrastructure become increasingly vital and contested naval forces require persistent subsea surveillance, high‑resolution seabed mapping, and reliable unmanned systems. Teledyne Marine delivers proven subsea technologies that support infrastructure protection, ISR, mine warfare, and reconnaissance in complex maritime operating environments.

SSW missions center on assuring access to critical seabed assets while enabling the detection, classification, and response to threats in contested waters. Teledyne Marine supports these missions through integrated surveys, sensing, and unmanned systems that help operators develop a clear operational picture and make informed decisions below the surface.

Teledyne Marine systems support the following SSW Missions:

• Seabed Infrastructure Protection
  Monitoring and assessing undersea cables, pipelines, and seabed installations through high‑resolution mapping, environmental sensing, and repeatable survey operations.
• Seabed Surveillance and ISR  
  Enabling subsea surveillance and intelligence, surveillance, and reconnaissance (ISR) through unmanned platforms, sensors, and data collection that improve situational awareness near the ocean floor.
• Mine Warfare (MCM and Seabed Survey)  
  Supporting mine countermeasure missions with accurate seabed characterization, route survey, object detection, and classification in complex underwater environments.
• Seabed Mapping and Reconnaissance  
  Delivering high‑resolution bathymetry and seabed mapping to identify terrain features, anomalies, and changes critical to seabed warfare planning and operations.
• Environmental Characterization for Undersea Operations  
  Providing long‑term monitoring of currents and seabed‑adjacent conditions to inform subsea operations, ISR, and infrastructure protection activities.
• Seabed Sensor and System Deployment Support  
  Supporting site characterization, deployment surveys, and data collection associated with fixed or semi‑persistent seabed sensor networks and undersea systems.​​​



Teledyne Marine systems have been demonstrated in real-world maritime defense exercises and operationally relevant environments supporting subsea and seabed warfare, harbor protection, underwater threat detection, anti-submarine warfare, mine countermeasures, and critical underwater infrastructure protection.​​

Solutions ​

Unmanned Underwater Vehicles ​

• Gavia AUV – provides defense operators with a proven, rapidly deployable autonomous platform for seabed reconnaissance, infrastructure protection, and underwater intelligence collection. Its modular design, operational flexibility, and low-logistics footprint make it an ideal solution for Subsea and Seabed Warfare missions where timely, high-resolution situational awareness is critical.
• Osprey AUV – delivers the flexibility, endurance, and advanced sensing capabilities required for today's evolving maritime defense missions. Built upon Teledyne Gavia's proven modular architecture, Osprey combines extended endurance and configurable payload options to support intelligence gathering, mine countermeasures, anti-submarine warfare, critical undersea infrastructure monitoring, and seabed reconnaissance.
• SeaRaptor AUV – provides defense operators with a powerful deep-water autonomous platform for seabed reconnaissance, infrastructure protection, and underwater intelligence collection. Combining abyssal-depth capability with advanced sonar and imaging systems, SeaRaptor delivers the detailed seabed awareness required for modern Subsea and Seabed Warfare operations.
