💰 Funding Details

European Defence Fund – Privacy-Preserving Human-AI Dialogue Systems


Overview

The call EDF-2025-LS-RA-CHALLENGE-DIGIT-HAIDP-STEP supports R&D actions that will deliver multilingual, secure, explainable and continuously-learning human–AI dialogue systems for defence. Grants are awarded as EDF Lump-Sum (EDF-AG-LS) agreements, simplifying cost reporting while enforcing milestone-based payments.


* Total budget per project: up to €20 million (lump-sum)

* Opening date: 18 Feb 2025

* Deadline: 16 Oct 2025, 17:00 (Brussels)

* Action type: Research Action in the form of a technological challenge

* Mandatory activities:

* Generating knowledge (AI dialogue research)

* Integrating knowledge (module integration into demonstrator)

* Participation in common testing environment and evaluation campaigns


Strategic Fit

The topic reinforces the European Defence Technological and Industrial Base (EDTIB) and meets STEP Regulation priorities in deep & digital technologies. Expected impacts include:


1. Trusted use of generative AI and LLMs in defence

2. Enhanced data sovereignty & classified-data handling

3. Faster, higher-quality decision-making for commanders

4. Multilingual operational readiness across all EU official languages


Eligible Consortia

* Minimum three independent legal entities from three different your country.

* At least two entities must be established in the EU or associated countries and not controlled by a non-associated third country.

* Participants must comply with the EDF Regulation 2021/697 security & ownership control rules.


Funding Model – Lump Sum Logic

The lump sum covers 100 % of eligible direct costs + 25 % flat-rate indirect costs, but payment is released only when the work packages and milestones defined in the Grant Agreement are fully achieved and positively reviewed.


Technology & Functional Requirements

* Written & spoken dialogue; near real-time latency

* Coverage of all 24 EU languages

* Explainability layer (XAI) for each answer

* Need-to-know logic for classified data segregation

* Continual learning from user supervision with no regression

* Off-line capable demonstrator (air-gapped deployment)


Synergies & Follow-Up

Successful consortia will be well positioned for subsequent EDIDP prototyping calls, NATO DIANA challenges, or dual-use commercial spin-offs (e.g. secured multilingual chat assistants for law-enforcement).

🇪🇺 Strategic Advantages

EU-Wide Advantages & Opportunities for the EDF 2025 Human-AI Dialogue Challenge


1. Single Market Access – 450 + Million End-Users in Uniform Conditions

- Defence ministries, EU agencies (e.g. FRONTEX, EU Satellite Centre) and security forces can procure a jointly-developed, multilingual system without duplicating national customisation costs.

- Common NATO/EU interoperability profiles (STANAGs, EU CIMIC doctrine) allow immediate embedding of the demonstrator into command-and-control (C2) suites used across Member States.

- A single certification & export license package (based on Council Common Position 2008/944/CFSP) opens doors to 30+ national defence budgets simultaneously, creating an addressable market far larger than any domestic programme.


2. Cross-Border Collaboration & Supply-Chain Resilience

- Consortium composition rule (≥3 entities from ≥3 Member/Associated States) forces inclusion of complementary best-in-class SMEs, primes and academic labs, mitigating single-supplier risk.

- Pooling of multilingual data assets (military corpora, acoustic models) reduces training-set bias and enables coverage of all 24 EU official languages far quicker than bilateral efforts.

- Trusted shared testing arena (the HAIDO challenge hub) provides a neutral “sandbox” where partners co-develop while retaining IP sovereignty through EDF’s regulated security clauses.


3. Alignment with Key EU Strategies

- Digital Decade & Digital Europe: contributes to target of 75 % EU businesses using advanced cloud/AI by 2030; interfaces natively with GAIA-X and the forthcoming European Defence Cloud.

- Strategic Technologies for Europe Platform (STEP): call explicitly labelled as STEP-compliant, allowing future access to STEP guarantee, equity and tax-incentive facilities.

- European Chips Act & Secure Connectivity synergies: on-device inference and sovereign sat-com backhauls for disconnected operations.

- Green Deal: energy-efficient model training (quantisation, federated learning) supports MoDs’ climate-neutral bases objective (EMAS).

- AI Act & Defence Exemption: early alignment with forthcoming risk-management obligations eases later dual-use commercialisation.


4. Regulatory Harmonisation Benefits

- Single set of EU Classified Information Handling (EUCI) guidelines simplifies security accreditation versus 27 divergent national regimes.

- Harmonised IP & data-sharing clauses (DEFLOG, EDAP) enable faster transfer from research to capability development.

- Mutual recognition of conformity assessments under the Cyber-Resilience Act accelerates market entry for derived cyber-secure modules.


5. Leveraging the EU Innovation Ecosystem

- Direct access to 3 000 + defence researchers via EDA CapTech AI & Big Data network and to 200 + HPC nodes through EuroHPC JU for model training.

- Synergistic testbeds: 5G-MIL (Italy), DIGI-lab (France), Bundeswehr Cyber Innovation Hub (DE) provide real operational data streams for reinforcement learning.

- Talent pipeline: Erasmus Mundus, European Universities alliances supply multilingual annotators and ethical-AI experts.


6. Funding Synergies & Blending Paths

- EDF → EUDIS (Defence Innovation Scheme): TRL uplift from 3-4 to 6-7 with follow-on prototyping calls.

- Combination with Horizon Europe Cluster 4 AI projects for underlying algorithms, Digital Europe for data spaces, and InvestEU/EIF for later scale-up capital.

- Regional smart-specialisation (ERDF) funds can co-finance secure datacentre upgrades hosting classified training data.


7. Scale & Impact – From Lab Prototype to EU-Wide Capability

- Federated architecture allows deployment in edge devices on naval vessels, forward operating bases and EU civilian crisis-management missions (CPCC).

- Multilingual voice interface enhances coalition interoperability and reduces cognitive load in joint operations.

- Potential spill-over into civilian domains (border control, disaster response, air-traffic management) aligns with Important Projects of Common European Interest (IPCEI) on Cloud and AI for dual-use uptake.


8. Key EU-Level Value Propositions at a Glance

- Economies of scale: shared R&D lowers unit cost by ≥30 % vs. national projects.

- Strategic sovereignty: EU-hosted LLMs reduce dependency on non-EU hyperscalers.

- Interoperability by design: common challenge environment ensures plug-and-fight integration.

- Regulatory readiness: proactive compliance with AI Act, DGA, NIS2.

- Funding continuum: clear pathway from EDF (research) → EUDIS/EIB (development) → Joint Procurement (deployment).

- Broader socio-economic impact: creation of high-skill jobs in language technology across all Member States and reinforcement of the European Defence Technological and Industrial Base (EDTIB).


> Take-away: Competing for this EDF grant unlocks unparalleled EU-wide leverage—financial, regulatory and market-access—transforming a single R&D effort into a strategically autonomous, multilingual AI capability deployable across the entire Union.
