Submarine data cables carry 99% of all intercontinental internet traffic. They also carry phone calls, financial transactions, and the data flows that underpin the modern European economy. Yet for years, this infrastructure has been treated as an invisible given—until a series of incidents across the Baltic Sea made its vulnerability impossible to ignore.
In February 2026, the European Commission responded with its most concrete action yet: €347 million in new funding, a Cable Security Toolbox, and a formal list of priority cable projects across the continent.
Why now? The threat landscape has changed
Between 2023 and 2025, a surge of submarine cable disruptions affected several EU member states—Germany, Finland, Lithuania, Sweden, and Latvia among them. Some incidents were attributed to accidents; others raised serious concerns about deliberate sabotage.
The EU had already signalled its concern a year earlier with a Joint Communication on cable security. By October 2025, a dedicated Cable Expert Group published a comprehensive EU risk assessment on submarine cable infrastructures, identifying specific threats, vulnerabilities, and dependencies. The February 2026 announcement translates that assessment into action.
The Cable Security Toolbox: a structured response
The toolbox is a coordinated framework developed jointly by the European Commission and member states through the Submarine Cable Infrastructure Expert Group. It sets out six strategic measures and four technical and support measures designed to improve cable security at every stage—before, during, and after an incident.
The framework covers the full resilience cycle: prevention, detection, response, recovery, and deterrence. It is intended to give member states and cable operators a common approach to risk, replacing fragmented national responses with coordinated EU-level action.
Cable Projects of European Interest (CPEIs)
Alongside the toolbox, the Commission published a list of 13 Cable Projects of European Interest. These are priority cable routes and systems identified as strategically important for EU connectivity and resilience over the next 15 years.
The CPEI designation guides public funding decisions and signals to investors and operators where EU support will be concentrated. Projects on the list will be eligible for dedicated funding calls in 2026 and 2027, totalling €267 million under the CEF Digital programme.
How the €347 million will be spent
The Commission amended the CEF Digital multiannual Work Programme (2024–2027) to redirect €347 million towards submarine cable projects. The funding is structured around three main areas:
- Cable repair capacity: two calls worth €60 million in 2026 to finance adaptable repair modules pre-positioned at ports or shipyards across EU sea basins, starting with the Baltic.
- SMART cable systems: a €20 million call for sensors and monitoring components integrated directly into submarine telecom infrastructure to gather real-time oceanographic and seismic data.
- CPEI funding: two calls in 2026 and 2027 totalling €267 million to support the construction and reinforcement of priority cable routes.
The repair module call is open exclusively to public bodies with an emergency response mandate—civil protection agencies, coast guards, navies, and national emergency response organisations.
A broader commitment: €533 million across the programme period
The February 2026 package does not stand alone. Under the full CEF Digital multiannual Work Programme for 2024–2027, a total of €533 million is allocated to submarine cable projects. Of that, €186 million had already been awarded to 25 projects before this announcement. Between 2021 and 2024, the EU invested €420 million in 51 backbone cable connectivity projects.
The scale of this commitment reflects a fundamental shift in how European institutions think about cable infrastructure—not as commercial telecoms, but as critical national and continental security infrastructure.
What this means for cable manufacturers and suppliers
Investment at this scale creates demand across the entire cable supply chain. New cable construction, repair modules, SMART monitoring systems, and the reinforcement of existing routes all require high-performance components that meet exacting specifications.
The cables that connect Europe’s coasts must withstand extreme pressure, saltwater corrosion, and mechanical stress over decades—with minimal opportunity for maintenance. Every material choice, from insulating tapes and water-blocking elements to reinforcing yarns and filler cords, has a direct impact on cable reliability and service life.
As EU funding accelerates deployment across the Baltic, Mediterranean, and Atlantic sea basins, manufacturers supplying this infrastructure will face increasing pressure to demonstrate that their components meet the most demanding standards.
JGili and the future of submarine cable infrastructure
At Juan Gili S.L., we have spent decades supplying specialist cable components to manufacturers across Europe. We understand the technical demands that critical infrastructure projects place on every element of a cable system—and we know that in submarine applications, there is no margin for compromise.
