The submission system is scheduled to open on June 10, 2025.

The EU Funding & Tenders Portal presents a call for proposals under the Horizon Europe program, specifically the DIGITAL CNECT (HORIZON-CL4-2025-03) call. The topic is "Preparing the Advancement of the state of the art of submarine cable infrastructures (CSA)" with the identifier HORIZON-CL4. This is a HORIZON Coordination and Support Action (HORIZON-CSA) with a HORIZON Action Grant Budget-Based [HORIZON-AG] Model Grant Agreement (MGA). The call follows a single-stage deadline model. The planned opening date is June 10, 2025, and the deadline for submission is October 2, 2025, at 17:00:00 Brussels time. The expected outcome of this call is to define a specific Research and Innovation (R&I) roadmap at the EU level. This roadmap aims to enhance cooperation between EU authorities and stakeholders to establish leadership in all relevant submarine cable technology domains. The roadmap will encompass all infrastructure related to the construction, operation, maintenance, and repair of submarine cables. Key stakeholders, including industry, research, and academic entities, should prepare, manage, and coordinate this CSA. The project should address the following overarching challenges: Reinforcing European leadership and cooperation in submarine cable connectivity, ensuring European capabilities and best practices shape future connectivity standards. This includes promoting the secondary use of these cables (e.g., for natural hazard pre-warning systems) and fostering synergies with CEF-Digital backbone projects. Facilitating a digital and green transition towards low carbon footprint connectivity platforms. This involves applying circular economy principles, reducing pollution, and regenerating natural systems, while ensuring the long-term sustainability, resilience, and security of submarine cable networks. Ensuring resilience for demanding cases that require a very high grade of Quality of Service (QoS) and performance. Conducting risk evaluation, preparedness, and prevention against future natural or man-made damage, including deliberate sabotage. The objectives of the target support actions are: Analyzing and defining the expected critical hardware and software components of future submarine cable infrastructure systems. This includes identifying opportunities for Europe to strengthen its capabilities, considering the characteristics and architectures, components, security, and operations of future submarine connectivity infrastructures. Defining the main required R&I work and assessing associated research investment needs related to the identified domains. Defining an appropriate industry roadmap (SRIA) in partnership with relevant EU actors from industry and academia. This roadmap should indicate priority research and innovation actions, their scope, and a timetable with milestones and targets. The project may organize thematic workshops to consult interested communities. The results will contribute to the work of groups such as the European Submarine Cable Expert Group, the NIS 2 Coordination Group, and the CER Group. The scope of the call includes enabling technologies applicable to submarine connectivity infrastructures and systems, including secondary uses for pre-warning systems against natural hazards. These technologies are crucial for ensuring Europe’s strategic autonomy and economic security. Europe needs to maintain a technological edge in cable technology and critical elements like repeaters, landing stations, operational control centers, underwater acoustic sensor networks (UASN), and cable communications cybersecurity. While some research occurs through mainstream activities in generic technologies (e.g., optical communications, network management software), specific research is needed for submarine cable infrastructures. The call aims to identify these specific research needs and develop a roadmap and SRIA for research and innovation in submarine cable technologies. Potential research areas include: Multi-core fibre (MCF) technology Digital Signal Processing Repeater systems Intelligent sensing Advanced Digital Acoustic Sensing (DAS) Strain and temperature sensing Oceanographic sensors for continuous, real-time trans-oceanic measurements (monitor water body) Logical layer and cable network management systems Underwater robotics for construction, maintenance, and repair Wireless sensor networks (WSN) for permanent infrastructure monitoring and threat detection Projects should develop synergies and complementarities with projects under CEF Digital, the Digital Europe Programme (DEP), and the Smart Networks and Services (SNS) Joint Undertaking. Integrating the gender dimension (sex and gender analysis) in research and innovation content is not mandatory. General conditions for admissibility, eligible countries, financial and operational capacity, evaluation, award, and legal/financial setup are detailed in the Horizon Europe Work Programme General Annexes. Proposal page limits and layout are described in Part B of the Application Form in the Submission System. Participation is limited to legal entities established in Member States, Iceland, Norway, associated countries, OECD countries, and MERCOSUR countries. Entities controlled by non-eligible countries or entities cannot participate. Application forms, evaluation templates, the HE Programme Guide, Model Grant Agreements (MGA), call-specific instructions, and additional documents such as the Ownership Control Declaration and relevant work programs are available in the Submission System and through provided links. The budget overview lists various topics under the HORIZON-CL4-2025-03 call, including DATA, DIGITAL EMERGING, HUMAN, and MATERIALS, with their respective action types (RIA, CSA, IA), budget allocations (ranging from €1,000,000 to €85,000,000), opening and deadline dates (June 10, 2025, and October 2, 2025, respectively), and indicative number of grants. Partner search announcements can be viewed and edited by LEARs, Account Administrators, or self-registrants after logging into the portal. The submission system is planned to open on June 10, 2025. This funding opportunity aims to bolster European leadership in submarine cable technology by creating a strategic roadmap for research and innovation.
