Naval & Maritime defence companies in Norway

Builds autonomous navigation systems and uncrewed surface vessels for maritime surveying, oceanographic research and defence operations.

The Otter

A compact 62 kg electric catamaran USV for sheltered and coastal waters, with up to 20 hours endurance and 30 kg payload capacity. Powered by four battery packs and two electric thrusters for zero-emission operations, it can be assembled by one person and transported in a cargo van. Used for bathymetric surveying, harbour security, scientific data collection and environmental monitoring in rivers and inland waterways.

The Mariner X

An open-ocean USV engineered for deep-water and harsh offshore environments, including Arctic and floating wind farm operations. At 9 metres and 5 tonnes it carries 1,200 kg of payload with 25 days of fuel endurance and a modular back deck for deploying AUVs, sonars and launch-and-recovery systems. Deployed by offshore operators including Argeo for long-range seabed mapping.

Comrod Communication Group develops tactical antennas, masts, naval antenna systems, mission systems and power solutions for defence and maritime communications.

Bergen-based manufacturer of electric ROV systems ranging from inspection-class units to heavy work-class vehicles rated to 7,000 metres, with over-the-horizon control via Starlink and Kongsberg Maritime Broadband Radio. Has delivered ROV systems to defence customers for more than 25 years.

Designs and manufactures professional underwater ROVs in Norway for defence, inspection, aquaculture and marine research, serving customers in 40+ countries.

Builds snake-like all-terrain autonomous underwater vehicles whose flexible body operates close to seabeds, slopes, ice and harbour structures where conventional AUVs cannot reach. The S-Series platform delivers high-resolution sonar and 3D photogrammetry for change and threat detection on critical subsea infrastructure.

Develops AI-enabled technologies for real-time multimodal underwater communication and submarine detection, specializing in magneto-inductive wireless communication systems to protect critical underwater infrastructure.

Hydroacoustics and sonar specialist supplying NATO navies with anti-submarine warfare training systems, torpedo countermeasures, sonar test and calibration kit and radar surveillance. Sonar3 is the company's latest signal-processing platform, developed with FFI for both manned and unmanned naval systems.

Develops software and hardware solutions for autonomous robotic systems operating in marine environments, specializing in mission-critical applications that require high degrees of self-dependence and robustness.

Builds inductive contactless slip rings that transfer power and data magnetically across air gaps for robotics, defence platforms and underwater drones, eliminating the wear and debris of traditional brush-based slip rings. Selected for NATO DIANA's 2026 cohort to adapt its underwater wireless charging technology for NATO defence needs.

Water Linked develops underwater sensors, DVLs, 3D sonar, acoustic positioning and modems for underwater robotics, public authorities, defence and subsea operations.
