Defence — European Union · Synthesis
A defence fragmented across 27 states with no integrated army, heavily reliant on NATO, but a major budgetary surge since the invasion of Ukraine, with a debate on strategic autonomy and common tools (European Defence Fund).
Citoyen synthesis for the Defence category in the European Union. Grounded in the bloc's data (EDA, SIPRI, IISS, NATO). ⚠️ Defence is a competence of the member states; the EU has no integrated army. All values are the latest realized observation available — never a forecast. Data last updated: June 2026.
1. State of play — where the EU's defence stands
A fragmented, national defence. Defence remains a competence of the member states: the EU has no integrated army, and capabilities are fragmented across 27 armies, with duplications and a lack of interoperability — an efficiency issue.
Reliance on NATO. The security of most members rests largely on NATO (and the American guarantee); 23 of the EU members are also members of the Alliance.
A budgetary surge. ⚠️ The invasion of Ukraine (2022) triggered a surge in defence spending across almost all members, with the aggregate effort approaching or exceeding 2% of GDP — a break after decades of underinvestment.
Support for Ukraine. The EU and its members are among the leading supporters (military, financial) of Ukraine, which has accelerated coordination and the defence industry.
Emerging common tools. Instruments are developing: European Defence Fund (EDF), joint procurement, permanent structured cooperation (PESCO) — a deepening, without challenging national primacy.
“Defence remains national: the EU has no integrated army and relies largely on NATO.”
2. Outlook — where defence is heading
Closing capability gaps. Reducing fragmentation and closing the gaps (ammunition, air defence) is the central issue.
Strategic autonomy. The debate on strategic autonomy (the ability to act without depending on the United States) shapes the period, as a complement to NATO.
Industrial base. Strengthening and coordinating the European defence industrial and technological base is a lever.
The open questions. Three issues will shape the period: (1) capability gaps; (2) strategic autonomy; (3) the defence industrial base.
“The invasion of Ukraine triggered a budgetary surge and revived strategic autonomy.”
3. International comparison — the EU among the powers
Placed in its environment, the EU is a bloc that is militarily fragmented but rearming.
Three takeaways. (1) Aggregate effort: ≈ 2% of GDP. Rising sharply, but spread across 27 armies, where the United States has an integrated force.
(2) A reliance on NATO. Unlike the United States, China or Russia, the EU does not have an autonomous integrated defence.
(3) A recent surge. ⚠️ Ukraine triggered increased rearmament and coordination.

| Power | Spending / GDP | Structure | Specificity |
|---|---|---|---|
| United States | ≈ 3.4% | integrated force | global power |
| China | ≈ 1.7% ⚠️ | integrated force | rising power |
| Russia | ≈ 6%+ ⚠️ | integrated force | war economy |
| France | ≈ 2% | national (deterrence) | power |
| European Union | ≈ 2% (aggregate) | fragmented (27) | NATO, autonomy debated |

Methodological note — the synthesis keeps sourced facts distinct from assessments, stays neutral, dates each figure, and does not extrapolate beyond the sources. ⚠️ Defence is a competence of the member states; the EU has no integrated army. The aggregate adds up 27 budgets and forces. Latest realized observation available (no forecast). Note generated by AI, human review required.
