Norway's Kongsberg Gruppen has won an international contract to install sonar and sensor systems designed to protect subsea critical infrastructure, the company said in early July 2026, in a deal that lands as governments and offshore operators ramp up spending on undersea security.
Sonar, Cameras And C-Scope Data Fusion
The system fuses active and passive sonar, cameras and data-processing software to detect and classify threats around high-value assets - including offshore oil and gas platforms, subsea communication cables, energy grids, ports and pipelines. At its heart is Kongsberg's C-Scope command system, which integrates multiple sonars and can extend to aerial and surface sensors for a common operating picture of a protected zone.
Divers And Small Submersibles In The Threat Set
Kongsberg says the systems can spot divers or small submersibles at ranges of several kilometres. The customer's identity and contract value have not been disclosed, but the Norwegian group described the project as commercially significant and centred on underwater surveillance and protection, with optional integration of aerial and surface sensors as it rolls out.
A Post-Nord Stream Market
Since the 2022 Nord Stream sabotage, European and NATO governments have pushed hard on subsea infrastructure protection, and Kongsberg has been positioning its autonomous underwater vehicles, sonar arrays and mission-control software for exactly this segment. Just last month, the group closed its acquisition of Zone 5 Technologies to expand its missile portfolio, and this run of deals has kept it in the frame across defence-industry procurement discussions in Europe and Asia.
Kongsberg's underwater bet dovetails with a wider defence surge: NATO allies just launched the HALO mega-constellation for sovereign satellite links, while the Pentagon signed multi-year FAMM cruise-missile deals with Anduril, CoAspire and Zone 5.
