IN Brief:
- Kongsberg has signed a contract with an unnamed international customer for critical infrastructure protection technologies.
- The project will focus primarily on underwater surveillance and protection.
- The requirement reflects rising demand for sensor, inspection, monitoring, and response systems around seabed infrastructure.
Kongsberg has secured a new international contract to deliver technologies for critical infrastructure protection, with the project focused primarily on underwater surveillance and protection.
The customer and contract value have not been disclosed, but the capability area is clear. Critical infrastructure now includes assets that are difficult to monitor, expensive to repair, and politically sensitive to disrupt: subsea telecoms cables, energy connections, offshore oil and gas installations, ports, transportation networks, and seabed infrastructure linked to national resilience. Protecting them requires maritime sensors, underwater vehicles, data processing, communications, and response planning.
The contract sits at the intersection of sea defence and cyber-physical national security. Subsea infrastructure can be threatened by sabotage, accidents, natural events, and cyber attacks on the systems that monitor or operate it. Protection is therefore a systems problem rather than a patrol problem. Operators need to know what is happening underwater, understand whether behaviour is normal or hostile, and move from detection to inspection or response quickly enough to reduce disruption.
The industrial requirements are substantial. Underwater surveillance systems require sonar, seabed sensors, autonomous underwater vehicles, remotely operated systems, navigation tools, acoustic communications, data fusion software, and ruggedised electronics. Many of those components must operate in harsh environments with limited access for maintenance. Reliability is not a secondary attribute in subsea protection. It is the foundation of the capability.
Subsea security has gained sharper political attention since incidents involving pipelines, cables, and maritime infrastructure exposed how vulnerable modern economies are below the waterline. Military and civil infrastructure are now intertwined. A cable outage can affect finance, government, and defence communications. Damage to energy infrastructure can create political and economic pressure without a conventional military strike. That ambiguity is driving investment in monitoring and attribution.
Maritime industrial work is already moving into less visible areas of support and resilience. Dockside additive manufacturing for submarine spares, explored through Clyde-based 3D printing work, shows how maintenance and recovery capacity are becoming part of undersea readiness. Kongsberg’s contract belongs to the same shift. Maritime capability is no longer limited to ships and submarines. It includes the industrial systems that maintain, sense, secure, and recover infrastructure across the maritime domain.
A modern underwater protection system has to combine persistent coverage with deployable inspection. Fixed sensors can provide warning, but they cannot examine every anomaly. Autonomous or remotely operated vehicles can inspect assets, but they need tasking, launch support, data links, and trained operators. Air, surface, and underwater assets then need to share enough information to support decisions. Software architecture becomes as important as hardware.
The contract also highlights a market opportunity for companies able to bridge commercial ocean technology and defence requirements. Offshore energy, seabed survey, hydrography, and maritime robotics have built a deep base of commercial expertise. Defence customers now want those tools hardened for security missions, integrated with command systems, and protected against cyber interference. Suppliers that can move between those worlds will have an advantage.
For Kongsberg, critical infrastructure protection aligns with existing capabilities across maritime systems, underwater technology, sensors, discovery, and defence integration. The challenge will be scaling from individual projects to a repeatable protection architecture. Every customer’s infrastructure is different. Water depth, seabed conditions, traffic patterns, legal jurisdiction, threat profile, and response authority all vary. Industrial success will depend on modular systems that can be configured without turning every contract into a bespoke engineering programme.
Cybersecurity should not be separated from the maritime layer. Underwater sensors and autonomous vehicles produce data that has to be trusted. Monitoring systems need secure communications, protected software, resilient timing, and controlled access. A compromised sensor network could be blinded, spoofed, or used to create false confidence. In infrastructure protection, data integrity is part of physical security.
Kongsberg’s order points to a defence market beginning to treat the seabed as a monitored, contested, and industrialised environment. Countries and infrastructure operators are moving from awareness of the threat to funded systems that can detect, inspect, and support response. Companies able to manufacture reliable underwater sensors, vehicles, and data systems will shape the next phase of maritime security.
