Europe’s Defence Rebuild: Where Things Stand in 2025
Europe is
undergoing its fastest defence rebuild since the Cold War. Russia’s
full-scale invasion of Ukraine, uncertainty about long-term US engagement, and
years of under-investment have pushed EU and NATO members into a historic
rearmament cycle. But is this happening under NATO, under a more autonomous
EU framework, or both?
This
article gives a clear overview of production, military capabilities, organisational
structures, and the delicate balance between NATO-centred defence and European
strategic autonomy.
1. A Historic Surge in
Defence Spending
The numbers
alone tell a story of major change:
- EU defence spending rose from €218 bn in 2021 to €343 bn in 2024, reaching 1.9% of EU GDP [1].
- As of 2025, all 32 NATO allies meet or exceed the 2% GDP guideline—up from only three in 2014 [2].
- NATO has adopted even more ambitious goals: 3.5% of GDP for core defence in the next decade, aiming for 5% by 2035 [3].
This is a
European defence renaissance, and it is happening at speed.
2. Rebuilding the Defence
Industrial Base
2.1 Emergency Measures
(2022–2025)
Europe
found itself critically short of ammunition and stockpiles after supporting
Ukraine, leading to rapid creation of new EU industrial tools.
Act in Support of Ammunition Production (ASAP)
A 2023
emergency instrument to increase artillery and missile production. ASAP’s first
€500 m package helped expand EU ammunition output significantly [4].
European Defence Industry Reinforcement through Common Procurement Act (EDIRPA)
A 2023
regulation providing €300 m in incentives for joint procurement, encouraging
standardisation and cross-European defence purchases [5].
These tools
were not meant to be permanent, but they opened the door to a deeper EU role in
defence industrial policy.
2.2 Long-Term Industrial
Framework
European Defence Fund (EDF)
With a
budget of roughly €8 bn for 2021–2027, EDF has become the EU’s flagship defence
R&D and capability development programme [6].
European Defence Industrial Strategy (EDIS)
Adopted in
2024, EDIS lays out a long-term plan to reduce fragmentation, ensure
supply-chain resilience, and promote joint European procurement [7].
European Defence Industry Programme (EDIP)
Adopted in
2025, EDIP builds long-term production capacity, focuses on supply-chain
resilience and stockpiling, and makes industrial expansion a structural rather
than emergency priority [8].
Industrial Challenges and the “Quantum Leap” Debate
Analysts
argue that the EU’s various defence-industrial programmes still require
consolidation and scaling up to truly match geopolitical needs [9].
Together,
these steps represent Europe’s first attempt at a coherent, long-term
defence-industrial policy.
3. Military Capabilities
and Force Integration
3.1 NATO Remains the
Warfighting Backbone
European
states are rebuilding heavy forces, air defences, readiness and logistics
overwhelmingly within NATO planning structures:
- NATO’s spending targets and
regional defence plans define capability requirements [3].
- European allies are building
brigades, air wings, and naval groups to fill NATO’s warfighting plans [10].
- Many states—especially on the
eastern flank—are moving toward the new 3.5% and 5% spending benchmarks [11].
NATO
retains the command structure, the nuclear umbrella and the collective-defence
guarantee.
3.2 The EU’s Own Military
Ambitions
- The EU is not building an army,
but it is building meaningful military tools.
- The EU promotes joint
capability development through PESCO, supported by EDA coordination and EU
funds [12].
- EDIS, EDIP, EDF and EDIRPA work
together to strengthen the defence industrial base and reduce supply-chain
vulnerability [7][8][9].
- The EU emphasises production
capacity, munition stocks, and standardisation as core priorities for the
coming decade [13].
While NATO
remains responsible for collective defence, the EU aims to ensure European
forces have the equipment, production base and interoperability
necessary to meet NATO targets.
4. Organisation and
Governance
Europe is
strengthening its defence governance, though not building a supranational
military structure.
- The European Commission
(especially DG DEFIS) now plays a major role in industrial strategy and funding
allocations [8].
- The European Defence Agency
(EDA) identifies capability gaps, structures cooperative projects, and
pushes interoperability [12].
- EU strategy documents stress
the need for a coherent demand-driven defence policy, aligned with both NATO
and EU capability goals [12][13].
Still, member
states retain sovereignty over armed forces, deployments and operational
command.
5. NATO vs Independent
European Defence
Is Europe
building an autonomous defence union? The answer is partially, but
mainly industrial and political—not military.
What remains NATO-led:
- Collective defence and Article
5
- Integrated command and control
- Nuclear deterrence
- Heavy warfighting plans
What the EU leads on:
- Industrial policy (EDF, EDIP,
EDIRPA, ASAP)
- Supply-chain resilience
- Joint procurement incentives
- Crisis-response tools
- Capability development
frameworks
Tension and complementarity
- NATO leaders regularly warn
against duplication, stressing that the EU should “complement, not duplicate”
NATO [12].
Strategic autonomy advocates argue the EU must be able to act even if US support weakens—hence the industrial push [7]. - In practice, Europe is building
a stronger European pillar inside NATO, not a replacement.
6. Conclusion
- Europe is rearming rapidly. The
EU is emerging as a powerful defence-industrial and capability-coordination
actor, while NATO remains the strategic and operational backbone.
- The emerging model is not “NATO or
Europe.”
It is NATO + a stronger, industrially competent, more coordinated Europe. - This dual structure may be Europe’s most
stable security architecture for the next decade.
