💰 Funding Details

EDF-2025-DA-UWW-AUWN-STEP – Funding Overview


What the Call Finances

* Mandatory activity blocks (must be fully covered in your work plan)

* Integrating knowledge (TRL 2-4 → 5)

* Studies (requirements survey, CONOPS, certification roadmap)

* Design (full UUSS / subsystem design, risk-reduction tests)

* System prototyping (early demonstrators up to TRL-7; selected subsystems up to TRL-8)

* Optional activity blocks (strongly recommended to maximise score & budget absorption)

* Testing (sea-trials, live demos in operational environments)

* Qualification (structural, electrical, thermal, radiation)

* Certification (military & dual-use standards: NATO STANAGs, IEC, DNV-GL, etc.)

* Life-cycle efficiency technologies (digital twins, predictive maintenance, green propulsion)


Eligible Applicants & Consortium Rules

1. Minimum legal composition – at least three independent legal entities from three different EU Member States or EDF Associated Countries, ≥ two of which are not controlled by the same third-country entity.

2. No foreign control on sensitive work – entities controlled by a non-EU/associated country can participate only in non-sensitive work packages and need MoD security assurances.

3. Supply-chain coverage – prime contractors, SMEs, mid-caps and research organisations must all be represented; strong SME participation (≥ 20 % of eligible costs) can trigger a *10 percentage-point funding bonus*.


Financial Intensity & Typical Reimbursement Rates (Art. 13 EDF Regulation)

| Activity Type | Union co-funding ceiling |

|---------------|-------------------------|

| Integrating knowledge, qualification, certification | 100 % |

| Studies | 90 % |

| Design | 65 % (75 % if SME-led) |

| Prototyping | 20 % baseline

(+10 pp if cross-border SME work ≥ 30 % of prototype cost) |

| Testing | 70 % |

| Life-cycle efficiency | Mirrors the activity it supports |


> Maximum Union contribution per grant: €79 000 000.

> Consortium budget may exceed this figure, but costs above the ceiling must be self-financed.


Other Key Funding Conditions

* Grant Model: Actual-cost, budget-based Action Grant (EDF-AG).

* Indirect costs: Flat-rate 25 % of eligible direct costs (unless declared under unit cost schemes).

* Pre-financing: ~45 % of EU share released at grant signature; later interim & final payments linked to milestones.

* IPR regime: Background/IP generated stays with partners; EU receives non-exclusive royalty-free licence for internal use; export restrictions apply (ITAR-free components strongly encouraged).

* Security costs & export licences: Eligible if clearly linked to the action (e.g. cryptographic hardware certification, site security).

* Synergy obligation: Proposal must reference and re-use results from prior EU projects (e.g. OCEAN2020, EDA PADR-UWW-UTS).


Timeline

* Call opens: 18 Feb 2025

* Q&A cut-off: 25 Sep 2025

* Submission deadline: 16 Oct 2025 – 17:00 CET

* Evaluation results: Feb 2026 (indicative)

* Grant Agreement signature: May 2026

* Indicative project duration: 48-60 months (align with TRL-7 exit)

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for "Advanced Underwater Networks" (EDF-2025-DA-UWW-AUWN-STEP)


1. Single Market Access: 450+ M Consumers, 27 Navies, 5 Seas

• A single development cycle can unlock procurement channels in all EU/EEA/EDF associated countries, replacing 27 fragmented tenders with one interoperable standard.

• Creates an EU-wide aftermarket for modular payloads, batteries, sensors, and AI software updates—lowering unit costs via volume production.

• Spin-off dual-use applications (critical-infrastructure inspection, offshore wind O&M, blue-economy services) gain instant passporting across the Internal Market (CE marking, EU Machinery & AI Acts), multiplying commercial revenue streams.


2. Cross-Border Collaboration & EDTIB Consolidation

• EDF consortia must include ≥3 entities from ≥2 Member States—built-in mechanism to form enduring industrial clusters that pool R&D, test ranges, and naval user feedback.

• Opportunity to integrate:

• Northern/Baltic expertise in cold-water operations (SE, FI, DK, EE).

• Atlantic anti-submarine know-how (FR, ES, PT).

• Mediterranean MCM & SBW competence (IT, GR, HR).

• Land-locked AI / cyber specialists (DE, AT, CZ).

• Strengthens sovereign EU supply chains for pressure-hull alloys, lithium-free batteries, acoustic modems—mitigating third-country dependencies called out in the EU Strategic Compass.


3. Regulatory Harmonisation & Common Standards

• EDF output feeds a single, non-proprietary UTS standard referenced by both EU EDSTAR and NATO STANAGs—eliminates costly retrofit/translation layers.

• Early alignment with upcoming EU AI, Cyber-Resilience and Underwater Cultural Heritage directives reduces certification time (optional task g/h) and speeds fleet deployment across borders.

• One conformity-assessment pathway for environmental impact (Green Deal) and military safety (MIL-STD / DEF STAN) instead of 27 national regimes.


4. Alignment with Flagship EU Policies

• Green Deal & Fit-for-55: promotes low-emission propulsion (fuel cells, advanced batteries) and life-cycle eco-design; potential access to Innovation Fund for maritime decarbonisation pilots.

• Digital Europe & EU Chips Act: fosters on-board AI accelerators, secure processors and edge-cloud links; may tap IPCEI-Microelectronics for low-power acoustic ASICs.

• Secure Connectivity / IRIS²: leverages EU sovereign sat-com constellation for tasking and data-backhaul of surface relays.

• STEP (Strategic Technologies for Europe Platform): call is STEP-labelled, facilitating blended finance from InvestEU & Recovery and Resilience Facility (RRF) for scale-up plants.


5. Access to Europe’s Innovation Ecosystem

• 5 000+ marine-tech researchers in EMODnet, 20+ maritime DIHs, 180+ EIT Manufacturing and ICT partners.

• Shared use of EU test infrastructures: NATO CMRE (La Spezia), EMSO underwater observatories, European Marine Robotics Test Ranges (UK/IE/PT/GR/NO via associate agreements).

• Fast-track access to EUDIS, DIANA and national defence innovation hubs for TRL-raising sprints.


6. Funding Synergies & Blended Finance

• Combine EDF grant (up to 100 % of eligible costs for prototypes) with:

• Horizon Europe Cluster 6 "Blue Economy" for dual-use sensing modules.

• CEF-Transport/Energy for integrating offshore wind farms & power-cable sensing infrastructure.

• ERDF / Just Transition funds for setting up regional assembly & maintenance centres in coastal regions.

• InvestEU defence window loans/guarantees to industrialise TRL 7→9.


7. Scale & Impact at EU Level

• Enables pan-European underwater situational-awareness grid interlinking UUV swarms, seabed nodes and renewable-energy platforms across all EU sea-basins—deterrence multiplier and critical-infrastructure shield.

• Supports multi-domain operations under EU Maritime Security Strategy 2023, boosting strategic autonomy and burden-sharing within NATO.

• Generates exportable EU standard—strengthens global competitiveness vs. US/Asian primes, opening EDF-associated markets (NO, IS, CH) and third-country FMS.


8. Concrete Opportunities for Applicants

1. Form a triad consortium: naval prime (system integrator) + SME swarm-AI specialist + offshore-wind operator to prototype seabed-sensor piggybacking—unique civil-military cross-fertilisation allowed only at EU level.

2. Bundle Baltic & Med navies to co-write a common Concept of Operations (mandatory task) and offer access to contrasting salinity/temperature ranges for accelerated qualification (optional task g).

3. Engage EU classification societies (DNV, Bureau Veritas) early to draft harmonised certification code—de-risking global export licensing.

4. Exploit CEF Digital to lay fibre in test ranges, feeding real-time datasets into GAIA-X compliant cloud—supporting AI model training and Digital Twin of the underwater network.


9. Long-Term Strategic Value for Europe

• Catalyses a vertically integrated, pan-European "blue defence tech" value chain—from battery chemistry to autonomous decision-making software—anchoring high-tech jobs in coastal regions.

• Acts as enabler for EU Critical Raw Materials Act objectives by safeguarding seabed resources exploration.

• Provides scalable architecture for future quantum-secure underwater communications and hybrid MCM-ASW missions, keeping Europe technologically ahead through 2040+.
