Strategic Options for EU-Ukraine Military Integration in the Absence of Rapid Accession

This strategic note examines how the European Union can advance deep military integration with Ukraine despite the recent indications that Kyiv’s formal accession may be delayed beyond 2030. Building on previous proposals for a unified European force, the integration of Ukrainian veteran units, and a new European security architecture, the document outlines three legally and politically viable pathways that do not require treaty change. These options include: (1) a Strategic Defence Partnership under Article 37 TEU, enabling Ukraine’s association with the European Defence Agency and the establishment of a European Strategic Reserve composed of Ukrainian veterans; (2) an expanded PESCO “Norway Plus” model, centred on a new umbrella project (“EU-UA Strategic Readiness Initiative”) integrating joint training, prototype testing, cyber defence, mixed brigades, and logistics; (3) a hybrid application of Article 42.7 TEU, through a European Council declaration extending mutual-assistance commitments to Ukraine alongside reinforced EPF support. The paper argues that these options are complementary and proposes a phased approach enabling the EU to achieve operational integration with Ukraine by 2027, thereby strengthening European defence credibility independently of the accession timeline.
