This funding call, under the HORIZON-CL4-2025-03-DATA-12 program, focuses on advancing submarine cable infrastructures. These infrastructures are crucial for ensuring Europe's strategic autonomy, technological leadership, and economic security in connectivity. The Coordination and Support Action (CSA) aims to define a comprehensive research and innovation (R&I) roadmap that will enable Europe to lead in submarine cable technologies.

The call targets innovations across various domains, such as cable materials, repeaters, landing stations, operational control, and underwater sensor networks. A key objective is integrating secondary applications like natural hazard pre-warning systems into submarine cable systems. The funded project will address the digital and green transition by emphasizing sustainability, low-carbon connectivity platforms, and adherence to circular economy principles.

The scope includes identifying critical hardware and software components, assessing R&I investment needs, and establishing a strategic research and innovation agenda (SRIA) for submarine cable technologies. Results will align with EU-level policy groups, including the European Submarine Cable Expert Group.

This initiative seeks collaboration among academia, industry, and relevant stakeholders to ensure resilience and high-performance submarine connectivity infrastructures, enhancing Europe’s position as a global leader in this field.
