IN Brief:
- Kongsberg Maritime has unveiled Arctic Hunter, a proposed 56-metre uncrewed vessel for the Royal Navy's Type 92 requirement.
- The design targets missions lasting up to 60 days, using a commercial Arctic hull with remote control and autonomous functions.
- Thales UK would supply sonar and communications, with construction proposed at Balaena Maritime's Birkenhead yard.
Norwegian marine technology company Kongsberg Maritime has unveiled Arctic Hunter, a proposed 56-metre uncrewed surface vessel designed to provide persistent anti-submarine surveillance for the Royal Navy’s emerging Type 92 programme.
The concept combines an established commercial Arctic vessel design with remote operating technology, autonomous functions, and military equipment supplied through a proposed partnership with Thales UK and Balaena Maritime. Kongsberg presented the design on 9 November ahead of the Atlantic Future Forum in Oslo, identifying construction in Birkenhead as its preferred industrial approach if the proposal is selected.
Arctic Hunter is designed for missions lasting up to 60 days and would operate from a forward support base inside the Arctic Circle. This proposed operating arrangement would reduce the need for repeated long-distance transits from British ports, allowing vessels to spend more of their available endurance undertaking surveillance tasks in northern waters. The company has not confirmed the final operating location or the support infrastructure that a Royal Navy programme would require.
The vessel is based on an existing commercial fishing vessel design developed for Arctic conditions. Commercial ships operating in the High North must withstand demanding sea states, low temperatures, and extended periods away from major ports. Kongsberg intends to adapt an established hull for uncrewed operation and military sensing, using existing maritime engineering as the foundation for the proposed naval platform.
Adapting a commercial hull does not remove the requirements associated with installing specialised equipment. The vessel’s structural arrangement, propulsion system, electrical capacity, and machinery spaces must accommodate remote operation and additional military systems. Engineering changes may also be necessary to control noise generated by the vessel itself, particularly when its mission relies on detecting acoustic signals from other objects underwater.
Thales UK would provide the submarine-hunting sonar and secure military communications equipment. The specific sonar model and complete installation configuration have not been disclosed. Kongsberg’s proposal centres on adding persistent sensing capacity to a wider naval surveillance network rather than equipping the vessel with a disclosed offensive weapons system.
Anti-submarine sensing depends on the relationship between sonar equipment, the surrounding water, and the platform carrying the sensors. Acoustic measurements can be affected by sea conditions, water temperature, salinity, background noise, and interference generated by the vessel’s machinery. A suitable installation must account for these factors while allowing collected information to be processed and transmitted to the personnel or other systems responsible for interpreting it.
Arctic Hunter would employ Kongsberg’s remote and autonomous technologies to undertake maritime operations without a conventional onboard crew. The company has previously developed uncrewed vessel systems that have received approvals involving classification society DNV and the Norwegian Maritime Authority. Those approvals relate to established technology and operating arrangements, rather than certification of the proposed Arctic Hunter military configuration.
Remote operation still requires personnel, communications infrastructure, and defined procedures for supervising the platform. A shore-based control centre can monitor vessel condition and movement while authorised operators manage selected functions. Autonomous systems may conduct tasks without continuous manual input, but the degree of independence must be established for each function and operating situation. Kongsberg has not disclosed the complete control architecture proposed for Type 92.
Maintaining an uncrewed vessel at sea for extended periods also places demands on machinery reliability and onboard monitoring. Propulsion and electrical equipment must operate without routine intervention by a crew aboard the ship, while faults need to be identified and managed through the available control and support arrangements. The proposed 60-day mission endurance is therefore a design objective requiring further evidence through platform development and testing.
The Arctic Hunter design includes substantial deck space and payload capacity intended to accommodate additional or alternative mission systems. Such flexibility could allow the vessel to be adapted as sensing and communications technology changes. Different payloads would nevertheless require verification of their structural, electrical, and control interfaces, and might affect the vessel’s operating characteristics or endurance.
Kongsberg proposes using commercial shipbuilding capacity to manufacture the hull before specialist military equipment is integrated. Balaena Maritime would provide construction capability at its Birkenhead yard, while Thales UK would contribute the sonar and communications systems. The companies intend to formalise their technology collaboration through agreements associated with the Atlantic Future Forum.
The proposed industrial arrangement could separate basic vessel construction from military systems integration, allowing established shipbuilding processes to support a specialist naval platform. Its delivery timetable remains conditional on the Royal Navy selecting the design and awarding the necessary contracts. Kongsberg has indicated that vessels could be available before the end of the decade, but no production quantity or contractual delivery date has been confirmed.
Type 92 forms part of the Royal Navy’s wider hybrid fleet plans, which envisage uncrewed platforms operating alongside conventional ships, submarines, and aircraft. Persistent surface-based sensing could supplement the surveillance undertaken by crewed anti-submarine warfare assets, providing additional information from positions distributed across a maritime area. The practical contribution would depend on the eventual sensor configuration and its integration with the wider naval network.
The proposal also aligns with UK-Norwegian cooperation on maritime security in the High North, including the Lunna House agreement supporting the development of autonomous capabilities. Kongsberg has identified potential applications among other NATO and Joint Expeditionary Force nations, although it has not announced orders from those customers for Arctic Hunter.
The next industrial steps involve formalising the proposed technology partnerships and pursuing the Type 92 requirement. Detailed design work, military systems integration, testing, and acceptance would follow any procurement decision. Arctic Hunter remains a proposed platform rather than a contracted or operational Royal Navy vessel.
