Kongsberg Doubles Norway’s Eyes at Sea: N3X Constellation Grows to Six Satellites
Kongsberg will deploy three additional N3X maritime surveillance satellites in early 2027, doubling its constellation to six. The Norwegian company said the expansion answers increased operational requirements from the Norwegian Armed Forces.
The additional capacity is intended to raise revisit rates and provide near real-time coverage of maritime areas, while widening the flow of surveillance data to Norwegian agencies and international partners.
Finding ships that do not want to be found
Each spacecraft carries an Automatic Identification System receiver together with passive radio-frequency sensors. That pairing addresses the central problem of maritime domain awareness. Commercial vessels are required to broadcast identity, position and course over AIS — until sanctions evasion, illegal fishing, smuggling or military activity gives them a reason to switch the transponder off or spoof it.
Passive RF listening closes the gap by picking up radar and communications emissions that continue regardless of AIS status. Operators can therefore detect dark vessels, identify spoofing and flag unusual behaviour. Beyond the armed forces, the Norwegian Coastal Administration, the Directorate of Fisheries and Norwegian Customs all draw on the data.
Three satellites made the case for six
The programme builds on three N3X satellites launched in 2025 and still operating. Kongsberg said their performance provided the basis for expansion.
Colonel John-Arild Bodding, commander of the Norwegian Armed Forces Space Operations Centre, said the results from the first three satellites confirmed the value of space-based maritime surveillance as a component of situational awareness, and that a larger constellation would improve coverage, responsiveness and the ability to monitor activity of interest.
Kongsberg chief executive Eirik Lie said rapidly deploying secure space-based capabilities is more critical than ever, pointing to the company’s ability to deliver satellites, ground infrastructure and data services as an integrated package.
A vertically integrated Norwegian stack
Satellite platforms come from Kongsberg NanoAvionics, ground services and operations from KSAT, with Kongsberg handling system integration and secure data delivery. The company owns every satellite in the constellation and runs N3X as a dual-use system, selling data to government and commercial customers while offering surplus capacity to allied nations. Kongsberg says capacity remains available for allies and partners seeking maritime domain awareness data.
Why the High North needs the coverage
Norway’s area of interest extends well past its territorial waters, across the Barents Sea, the Norwegian Sea and into the Arctic — the surveillance responsibility of NATO’s northern flank. Russian Northern Fleet basing on the Kola Peninsula, submarine transit routes and recent incidents involving undersea cables and pipelines have all raised the premium on persistent watch.
Space-based sensing offers what aircraft and patrol vessels cannot: wide-area, persistent coverage that is harder for an adversary to interfere with. Doubling from three satellites to six roughly doubles how often a given stretch of ocean is seen each day — which, in practice, is what turns detection into tracking.
