The European Court of Auditors has warned that achieving military readiness across the European Union by 2030 remains difficult despite major funding increases.
In a report published on Wednesday examining developments since 2020, the Luxembourg based watchdog cautioned that money alone cannot overcome deep structural challenges, slow political coordination, and severe industrial bottlenecks across member nations.
Total defense spending across EU member states surged by almost 80 percent between 2020 and 2025 as governments responded to a deteriorating European security environment. For decades following the end of the Cold War, European defense budgets faced persistent underinvestment, resulting in depleted ammunition stockpiles, severe shortages of missiles, extended production lead times, and heavy reliance on military suppliers outside Europe.
European defense manufacturers are attempting to expand production capacity, boost innovation, and build new partnerships. The European Union, which brings together 27 member states, has historically focused on economic integration, leaving military procurement primarily under the authority of national governments.
Funding fragmentation and industrial bottlenecks
The audit body warned that a lack of effective European level planning and inadequate coordination between various EU and national funding tools could lead to fragmented investments. Without unified coordination, auditors noted that duplicated efforts or critical gaps in military capabilities are likely to emerge across member nations.
Auditors pointed out that the abrupt increase in available funding could create severe new bottlenecks for defense manufacturers. Defense companies face shortages of raw materials, key components, and specialized personnel, making it difficult for the industry to absorb funds efficiently.
The ECA also highlighted that current funding may prove insufficient to cover all agreed defense priorities. One key area facing potential shortfalls is military mobility, which focuses on upgrading transport infrastructure such as bridges, railways, and ports to ensure troops and heavy equipment can move rapidly across European borders during a crisis.
Surging debt risks and financial commitments
The watchdog expressed particular concern regarding the growing reliance on borrowing backed by guarantees from the EU budget. The report highlighted 150 billion euros allocated under the Security Action for Europe, known as the SAFE program, as a prime example of large scale financial commitments relying on central budget backing.
Auditors also pointed to a 90 billion euro loan package provided to Ukraine, of which 60 billion euros is designated specifically for defense purposes. The European Union has significantly expanded financial assistance to Kyiv in response to ongoing military conflict in Eastern Europe.
Financing defense spending through increased borrowing and EU guaranteed loans could burden the sustainability of public finances, the report warned. High debt levels risk slowing down public debt reduction for member states while placing additional pressure on the long term European budget.
Industrial opportunities and strategic autonomy
Despite fiscal and structural risks, the ECA estimated that increased funding and the changed security environment create important opportunities to strengthen Europe's defense industrial and technological base. Expanding production capacity can drive innovation while fostering new forms of cooperation, including defense collaborative clusters and capability coalitions.
Auditors noted that the bloc has an opportunity to strengthen strategic partnerships, particularly with Ukraine, and provide financial incentives for member states to procure defense systems from European suppliers. Implementing European preference clauses could help reduce long term dependencies on suppliers outside Europe.
However, the ECA concluded that achieving EU strategic autonomy by 2030 and maintaining independent high intensity military operations will be particularly demanding. Major constraints include the fragmentation of national military systems, industrial bottlenecks, slow political coordination, and ongoing reliance on the United States.
The United States has served as the primary security guarantor for Western Europe through the North Atlantic Treaty Organization since 1949. Strategic autonomy refers to the European Union's goal of developing independent military capabilities so it can manage regional crises without relying entirely on American intelligence and firepower.
Governance challenges and audit limitations
The complexity of governance structures and accountability mechanisms in European defense policy also increases the risk of overlapping responsibilities among different bodies, according to the report. Overlapping mandates between EU institutions and national defense ministries can create administrative confusion and slow down decision making during security crises.
Finally, the ECA pointed out that the audit court itself lacks an audit mandate over all entities and funding instruments involved in European defense policy. Based in Luxembourg, the European Court of Auditors serves as the official financial watchdog of the EU, but its oversight authority is limited by specific treaty provisions.
Moving forward, auditors emphasized that European leaders must improve planning, streamline governance, and resolve industrial supply chain constraints if the bloc is to meet its ambitious 2030 defense readiness targets.
