Critical Technologies for European Defence: Where Policy Innovation Meets Military Need

Babis Papaspyros

 1. The big Picture 

Europe is entering an important decade for defence innovation. Geopolitical tensions, fast‑moving technology, and the need for strategic autonomy are pushing the EU to rethink how it finds, funds, and turns critical defence technologies into real military systems.

The main point is simple: Europe’s success will depend on turning policy ideas into real military capabilities and Greece must speed up reforms to avoid being left behind in Europe’s new defence‑industrial landscape

2. Strategic Context: Why Critical Technologies Matter Now

Europe’s defence environment has fundamentally changed since 2022. Three dynamics define the current landscape:

Operational Urgency

The war in Ukraine has demonstrated the decisive role of drones, counter‑UAS, electronic warfare, space‑based ISR, and rapid prototyping cycles. The battlefield has become a laboratory where software‑defined capabilities evolve faster than traditional procurement cycles.

Industrial Urgency

Europe faces production bottlenecks, fragmented supply chains, and dependence on non‑EU technologies. Ammunition shortages, limited manufacturing capacity, and slow certification processes have exposed structural vulnerabilities.

Technological Urgency

AI, autonomy, quantum, cyber, and advanced materials are advancing at a pace that challenges legacy defence‑industrial models. The EU must ensure that innovation ecosystems deliver operationally relevant solutions at speed.

Critical technologies are no longer “future capabilities”, they are current operational requirements. The EU’s challenge is to align policy innovation with military need.

3. The EU Defence‑Innovation Architecture

Europe’s defence‑innovation ecosystem has expanded significantly in the last five years. The following structures form the backbone of the EU’s approach.

3.1 European Defence Fund (EDF)

The EDF is the EU’s flagship instrument for defence R&D and capability development.

Key features:€1 billion annual budget

Focus on collaborative projects across Member States

Emphasis on AI, autonomy, sensors, space, materialsSupports both early research and prototyping

The EDF aims to create a single European defence‑innovation market, reducing fragmentation and incentivising cross‑border industrial cooperation.

3.2 EUDIS – European Defence Innovation Scheme

EUDIS is the EU’s dedicated framework for startups, SMEs, and non‑traditional defence actors.Its tools include:EUDIS Challenges (rapid innovation competitions)

Defence Equity Facility (€100M for dual‑use startups)

Innovation Test Beds for prototyping and experimentationEUDIS reflects the EU’s recognition that defence innovation must integrate civilian innovators, research centres, and agile technology developers.

3.3 DIANA (NATO)

DIANA provides:A network of accelerators and test centresFunding for dual‑use technologiesA bridge between NATO operational requirements and European innovators

DIANA reinforces the need for interoperability, shared standards, and common testing environments.

3.4 EDIRPA and ASAP – Industrial Urgency InstrumentsTwo new instruments reflect Europe’s shift from R&D to production capacity:

EDIRPA: Joint procurement to replenish stockpiles

ASAP: Act in Support of Ammunition Production

These instruments highlight that innovation must be linked to industrial scalability.

3.5 The Strategic Compass and Critical Technologies List

The Strategic Compass identifies priority technology areas:

• AI and autonomous systems
• Cyber defence
• Space technologies
• Quantum and advanced computing
• Hypersonics
• New materials and energy systems
• Counter‑UAS and electronic warfare
• Secure communications and Positioning, Navigation, and Timing (PNT).

This list guides EU funding, capability planning, and industrial policy.

4. Where Policy Innovation Meets Military Need

The EU’s defence‑innovation policy is shifting from technology‑push to capability‑pull. Three principles define this shift.

4.1 Operational Relevance Innovation must be driven by real military needs, not abstract research agendas. Ukraine has shown that:

• Cheap, expendable systems can be decisive
• Fast development cycles work better than long procurement processes
• Data, software, and autonomy matter as much as hardware

4.2 Dual‑Use Integration

Most critical technologies originate in the civilian sector. Europe must:

• Incentivise civilian innovators to enter defence markets
• Reduce regulatory and cultural barriers
• Provide clear pathways from prototype to procurement

4.3 Industrial Scalability

Innovation without production capacity is strategically irrelevant. The EU must ensure:

• Common standards
• Shared testing infrastructure
• Joint procurement
• Industrial resilience

This is where many Member States including Greece face structural weaknesses.

5. Greece’s Defence‑Innovation Ecosystem: Strengths and Structural Gaps

Greece has strong scientific talent, a growing tech sector, and significant operational experience in complex security environments. However, its defence‑innovation ecosystem remains fragmented, under‑funded, and slow to integrate with national and EU related structures.

5.1 Structural Weaknesses

Fragmented R&D Landscape Universities, research centres, SMEs, and defence companies operate in silos. They lack systematic collaboration, have few joint programmes, and operate without a coherent national strategy, leaving the innovation ecosystem fragmented.

Limited Industrial Base

Greece lacks mid‑tier defence companies capable of scaling prototypes into production.

Procurement Barriers

The Greek procurement system is slow, risk‑averse, and oriented toward off‑the‑shelf solutions.

TRL Mismatch

Preference for TRL 7+ excludes early‑stage innovators.

Limited Testing Infrastructure

Few accredited test ranges for drones, autonomy, EW, or robotics.

5.2 Emerging Strengths

ΕΛΚΑΚ (Hellenic Centre for Defence Innovation) is putting the Greek defence– Two Years of Operation

EΛKAK is Greece’s first attempt to create a centralised defence‑innovation authority.

Contributions:

Establishing a national framework Launching initial calls for proposals

Creating a MoD–ecosystem bridge

Raising awareness among SMEs and researchers

Limitations:

Under‑resourced

Constrained by procurement rules

Limited agility for rapid prototyping

The Defence Innovation Hub at JOIST

The newly established hub at JOIST represents a bottom‑up, ecosystem‑driven model aligned with European best practices.

Strengths:

EU SECRET certification

Access to testbeds, labs, prototyping infrastructure

Strong links with academia, startups, international partners

Ability to host consortia and run challenges

JOIST complements EΛKAK by providing the agility, experimentation capacity, and innovation culture that government structures often lack.

6. How Greece Can Align with EU Defence‑Innovation Policy

To fully integrate into the European defence‑innovation ecosystem, Greece must pursue reforms in four areas.

6.1 Governance and Strategy

Greece needs a National Defence Innovation Strategy aligned with:

Hellenic Armed Forces Operational Requirements

EDF priorities

EUDIS challenges

NATO DIANA focus areas

EU Critical Technologies List

6.2 Procurement Reform

Greece must adopt:

Fast‑track procurement for prototypes

Sandbox environments for experimentation

Multi‑year innovation budgets

Pre‑commercial procurement mechanisms

6.3 Industrial Development

Greece should invest in:

Mid‑tier defence companies

Dual‑use technology accelerators

Partnerships with Greek & European primes

6.4 Strengthening EΛKAK and Integrating JOIST & other entities

A complementary model:ELKAK: Strategy, funding, certification, military requirements

JOIST: Prototyping, testing, challenges, SME integration, EU project hosting

This mirrors successful models in the UK, France, and the Netherlands.

7. Critical Technologies Where Greece Can Lead

Greece has realistic opportunities to specialise in areas aligned with EU priorities:

• UAVs, UGVs and USVs
• Counter‑UAS
• Electronic warfare
• AI‑enabled surveillance
• New materials 
• Energy systems for remote operations
• Cyber

These niches align with both EU funding and Greek operational realities.

8. Recommendations

Europe must bridge the gap between policy innovation and military capability

Critical technologies require ecosystem thinking, not isolated projects

Greece must accelerate reforms to avoid strategic marginalisation

EΛKAK and JOIST represent a promising dual‑structure model

The next decade will determine whether Europe becomes a global defence‑innovation actor

9. Conclusion

Europe’s defence future will be shaped by its ability to innovate at speed, scale, and operational relevance. Critical technologies—AI, autonomy, cyber, space, quantum, advanced materials—are redefining warfare and industrial power.

For Greece, the challenge is clear: move from fragmented efforts to a coherent national innovation ecosystem. 

Strengthening Greece’s defence and dual‑use innovation ecosystem ultimately depends on building a culture of structured cooperation. Despite the presence of strong ideas, capable researchers, and promising technologies, stakeholders often operate without systematic collaboration, joint programmes, or a unified national strateg, leaving innovation fragmented and slow to mature. In a country where the number of actors is limited, no one is expendable: universities, research centres, SMEs, startups, defence companies, and public institutions must align their capabilities and work as an integrated network. Only through coordinated synergies can Greece transform good ideas into capabilities.

This is not only essential for competitiveness within the European defence‑innovation landscape but also critical for strengthening Greece’s national defence and security, ensuring that promising technologies translate into real operational advantages
