Europe's Defense Shift: Between Transatlantic Dependence and Strategic Autonomy

The European NATO states find themselves at a strategic turning point in their defense policy in March 2026. New data from the Stockholm International Peace Research Institute (SIPRI) document a significant shift in arms import patterns, while the EU Defense Commissioner warns of a critical production gap in air defense missiles. These developments mark the beginning of a fundamental realignment of the European security architecture.

According to the SIPRI figures published on March 9, 2026, the share of the United States in the arms imports of European NATO members fell to 58 percent during the period 2021-2025, compared to 64 percent in the previous five-year period. This seemingly moderate reduction of six percentage points signals an accelerated diversification process catalyzed by increasing doubts about the reliability of the U.S. as a security guarantor. The repeated threats from President Donald Trump against allies and his focus on defending the American homeland have significantly shaken transatlantic trust.

The emerging gap is increasingly being filled by alternative suppliers. South Korea was able to increase its market share from 6.5 to 8.6 percent, establishing itself as a serious competitor in the European arms market. Israel nearly doubled its share from 3.9 to 7.7 percent, while France, as the leading intra-European arms nation, was able to expand its share from 6.5 to 7.4 percent. These figures reflect not only a geographical diversification of supply sources but also a strategic reorientation of European procurement policy.

Particularly noteworthy is Germany's rise to the fourth-largest arms exporter in the world, with 24 percent of German arms exports flowing to Ukraine. Germany has thus displaced China from fourth place and demonstrates the industrial mobilization capability of the European defense economy. Italy climbed from tenth to sixth place, with 59 percent of its exports going to the Middle East. These developments underscore the potential for increased intra-European arms cooperation.

Nevertheless, the structural dependence on American military technology remains considerable. By the end of 2025, twelve European states had ordered or planned to order a total of 466 F-35 fighter jets, including 39 aircraft ordered or planned for 2025. In advanced air defense systems and long-range interceptors, the U.S. remains the dominant supplier. This technological dependence in critical capability areas significantly limits Europe’s strategic freedom of action.

The acute dimension of this dependence is revealed in the analysis presented by EU Defense Commissioner Andrius Kubilius in Poland on March 6, 2026. Ukraine alone needed around 700 Patriot interceptors during the four-month winter season to counter Russian missile attacks. However, the production capacity of the manufacturer Lockheed Martin was only 600 PAC-3 missiles in 2025. Kubilius warned that the U.S. would not be able to provide enough missiles for the Gulf states, its own forces, and simultaneously for Ukraine.

The recent escalation in the Middle East has dramatically exacerbated this scarcity. According to Ukrainian President Volodymyr Zelensky, over 800 American missiles were deployed within three days to intercept Iranian missiles and drones. Zelensky bitterly emphasized that Ukraine has never had such a quantity of interceptors. This competition for limited production capacities forces Europe to develop its own industrial capabilities.

The EU is attempting to address this challenge with new financing instruments. A planned loan of 90 billion euros for Ukraine over the next two years is intended to be used two-thirds for military expenditures, with purchases from Ukrainian and European manufacturers prioritized. Additionally, 19 EU member states, including Poland, have applied for access to the 150 billion euro defense credit program. However, Hungary is blocking the urgently needed loan, which is supposed to flow starting in April, due to an energy dispute with Ukraine.

Polish Defense Minister Władysław Kosiniak-Kamysz emphasized on March 6 the growing importance of independent European arms production and secure supply chains. Poland itself has signed extensive contracts for American military equipment and is closely monitoring whether conflicts elsewhere could slow down deliveries. The uncertainty regarding American delivery commitments intensifies the European drive for independence.

NATO guidelines for 2026 require that at least 25 percent of member states' defense procurement budgets be allocated for digital and autonomous capabilities—a figure that was below ten percent five years ago. This requirement reflects the technological transformation of modern warfare but poses significant challenges for smaller European states in procuring highly specialized systems.

The European Defense Fund (EDF) will dedicate about a quarter of its budget in 2026 to emerging technologies that are expected to shape the future of warfare. This investment in innovation is essential to maintain technological parity with the U.S. and China. At the same time, the fragmentation of the European arms market into national procurement programs necessitates increased coordination.

The strategic analysis shows that Europe is in a critical transitional phase. Defense spending in the European Union increased by 60 percent between 2020 and 2025 to over two percent of GDP. President Trump demanded at the Munich Security Conference in 2026 that allies increase their military spending to "well over three percent" of national GDP. This demand reflects the American expectation of a greater European burden-sharing.

However, higher spending alone does not guarantee strategic autonomy. The technological dependence on critical systems, the fragmentation of the European arms industry, and limited production capacities require structural reforms. The EU must find a balance between accelerating its own production capacities and maintaining transatlantic arms cooperation.

Commissioner Kubilius's "Missile Tour" through Poland, Italy, Germany, Belgium, Sweden, and Finland symbolizes the attempt to develop a coordinated European response to the production crisis. The reality, however, remains that Europe will need years to close the production gaps and achieve true strategic independence. In this interim phase, the transatlantic alliance remains, despite all tensions, the backbone of European security—a reality that requires both humility and urgency in developing European self-capacities.
