EU defence integration hampered by data gaps in countries’ procurement reporting

EU defence integration is significantly hampered by persistent data gaps in Member States' collaborative equipment procurement reporting. Despite a robust legal framework encompassing initiatives like Permanent Structured Cooperation (PESCO) and the European Defence Fund (EDF), only 12 EU countries consistently provide the necessary data. This lack of transparency impedes strategic planning, hinders the identification of capability shortfalls, and undermines efforts to foster a more integrated and efficient European defence market. The challenge lies in balancing national security interests and commercial confidentiality with the imperative for greater interoperability and collective defence capabilities, necessitating a re-evaluation of current reporting mechanisms and compliance enforcement.

This data deficit is not merely an administrative inconvenience; it poses a fundamental challenge to the strategic objectives of the Common Security and Defence Policy (CSDP) and its instruments. Without a clear and complete picture of what Member States are procuring together, the EU's ability to identify common capability gaps, avoid duplication, foster interoperability, and allocate resources efficiently is severely compromised. This article will delve into the legal and practical implications of these data gaps, examining the existing EU defence procurement framework and highlighting the urgent need for enhanced transparency and compliance to advance genuine defence integration.

Complementing these efforts, Regulation (EU) 2021/697 established the European Defence Fund (EDF), a flagship instrument designed to co-finance collaborative defence research and capability development projects among Member States' industries. The European Defence Agency (EDA) plays a crucial role in collecting and compiling annual defence data from all 27 Member States, including total defence expenditure, investment, and collaborative investment, with its Ministerial Steering Board Decision of November 2005 providing the basis for this data collection. Under PESCO, Member States are also required to submit national implementation plans outlining their capabilities and commitment to fulfil agreed objectives, with the High Representative reporting annually on the status of PESCO implementation based on EDA contributions.

The implications of these data gaps are far-reaching. Without comprehensive data, the EU struggles to conduct an effective Coordinated Annual Review on Defence (CARD), which is crucial for identifying capability shortfalls and guiding investment. This fragmentation in data collection directly hinders the EU's ability to achieve economies of scale, reduce duplication, and enhance interoperability among national armed forces. The absence of a complete picture also makes it difficult to assess the true impact of EU defence spending, which reached €343 billion in 2024, and to ensure that investments are strategically aligned with common EU defence priorities. The European Commission itself has acknowledged the administrative burden of statistical reporting, even proposing to reduce some obligations under Directive 2009/81/EC, which could further exacerbate data visibility issues if not carefully managed.

Moving forward, the EU must address the underlying reasons for these data gaps, potentially through clearer, more harmonised reporting standards, robust verification mechanisms, and incentives for compliance that balance national security concerns with the collective need for transparency. Legal professionals should advise their clients to advocate for and adapt to improved reporting frameworks, recognising that greater transparency, while challenging, is ultimately essential for strengthening the European Defence Technological and Industrial Base and achieving genuine strategic autonomy. The effectiveness of future EU defence integration hinges on the political will to overcome these data challenges and foster a culture of shared responsibility and openness.
