The Stockholm International Peace Research Institute (SIPRI) has released its comprehensive data on the global trade in major weapons for the five‑year period from 2021 to 2025, revealing a dramatic restructuring of arms import patterns. For the first time in SIPRI’s historical records, Europe collectively has become the world’s largest importing region for major arms systems, outweighing long‑standing importers in Asia, the Middle East and other regions. According to the report, European countries as a whole accounted for approximately 33 % of the global volume of arms imports over this period, a more than three‑fold increase compared with the 2016–2020 period, when Europe’s share stood at just 12 % of worldwide arms receipts.
The primary driver behind this shift is the security environment facing Europe, particularly in light of Russia’s full‑scale invasion of Ukraine in February 2022. While Ukraine itself continued to import substantial quantities of weapons in support of its defence efforts, European states beyond Ukraine significantly increased their acquisition of armaments to strengthen deterrence, modernise capabilities, and reduce decades of under‑investment in national defence. Though SIPRI data shows Ukraine capturing a notable share of weapons deliveries as part of military aid flows, the report’s regional analysis places Europe overall ahead of Asia and the Middle East in terms of aggregated import volume. SIPRI’s assessment underscores that while conflict‑induced demand to Ukraine was a visible element, nearly all European states increased their imports to address perceived security risks arising from Russia’s actions and broader strategic uncertainties.
SIPRI’s figures also reveal that the total volume of international transfers of major arms — including aircraft, missiles, combat vehicles, artillery, and air‑defence systems — rose by roughly 9.2 % in 2021–25 compared with 2016–20, making this the most significant growth in the global arms trade since the period between 2011 and 2015. Much of this expansion is attributable to the surge in European arms imports. Notably, while Europe’s share of imports skyrocketed, other regions experienced mixed trends: Asia and Oceania accounted for about 31 % of global arms imports, while the Middle East’s share declined to around 26 %, reflecting shifts in procurement rhythms and contract fulfillment cycles across regions.
Despite concerted efforts by European states to expand domestic arms production and develop regional defence industrial bases, foreign suppliers remained indispensable to meeting urgent capability gaps. The United States in particular emerged as the dominant source of imported systems for European customers, providing advanced platforms such as fighter aircraft, long‑range air‑defence systems, and other high‑end technologies. SIPRI’s analysis indicates that the United States supplied nearly half of all arms imported by Europe in the latest period, cementing its role as the pre‑eminent global arms exporter and a central component of European defence planning.
In addition to the United States, other Western suppliers, including countries such as Germany, France, and other European states, contributed arms to European procurement, both directly and through collaborative industrial partnerships. Nonetheless, the scale and sophistication of systems provided by the United States meant that it retained a highly influential position in shaping European militaries’ capability portfolios. By contrast, Russia’s position as a key supplier to global arms markets continued to erode in the 2021–25 period, with its share of exports shrinking significantly due to conflict, sanctions, and shifting geopolitical alignments that have constrained its access to many traditional markets.
SIPRI’s data also highlighted broader patterns in global arms importers and exporters beyond Europe. India emerged as the second‑largest arms importer during the same five‑year period, accounting for approximately 8.2 % of total global arms imports. India’s procurement was characterised by a continuing diversification away from traditional reliance on Russian equipment toward a broader portfolio of Western and domestic systems, reflecting long‑term strategic recalibrations in defence procurement. The ranking of importers and exporters, as well as supplier market shares, underscores the complex interplay between national security imperatives, geopolitical alliances, and industrial capacities that define the contemporary arms trade.
The rise of Europe as the largest global recipient region for major arms underscores several key themes in international security. First, it reflects a tectonic shift in how European governments prioritise defence spending and capability development in the face of renewed territorial threats and questions about the continuity of extended deterrence guarantees. Second, it highlights the interconnected nature of modern arms markets, where regional demand surges can substantially alter global trade volumes and supplier rankings. Finally, it places into stark relief the enduring influence of major exporters like the United States, whose industrial and technological leadership continues to shape global defence relationships and power projections.
Experts analysing the SIPRI data point to the war in Ukraine as a catalyst that accelerated trends already underway before 2022. Prior to the conflict, Europe had begun incrementally increasing defence expenditures and procurement to address evolving threats, but this trajectory steepened sharply after February 2022. The scale and urgency of arms imports reflect not only contributions to Ukraine’s defence but also efforts to modernise core national forces and address systemic capability shortfalls that had accumulated over decades of comparatively low investment.
The implications for NATO and transatlantic security cooperation are significant. With European states investing heavily in imported systems, interoperability with U.S. and allied forces becomes even more central to collective defence frameworks. At the same time, European defence industrial initiatives aimed at expanding domestic production capacity seek to reduce long‑term dependence on external suppliers and foster strategic autonomy. Balancing these dual objectives — sustaining effective alliance architectures while nurturing indigenous industrial bases — will be a central policy challenge for European governments in the years ahead.
Beyond immediate procurement figures, SIPRI’s findings also highlight strategic shifts that may influence future security architectures. The reorientation of arms import flows toward Europe signals a convergence of threat perceptions across the continent, and by unifying procurement efforts around common capability requirements, European states may deepen defence cooperation mechanisms from joint acquisition programmes to integrated logistics and sustainment networks. Such developments align with broader policy goals articulated by the European Union and NATO allies to strengthen collaborative defence planning and reduce redundancies in national procurement strategies.
At the same time, the global landscape of arms transfers remains dynamic and subject to evolving geopolitical pressures. While Europe’s pre‑eminence as the largest importer could persist if current security concerns remain acute, shifts in conflict zones, diplomatic realignments, or breakthroughs in defence technology could recalibrate global import and export balances. The nature of conventional weapons procurement — often involving multiyear delivery schedules, offset agreements, and long negotiation cycles — adds further complexity to projecting future trends with precision.
SIPRI’s full report, which includes detailed data on national and regional arms transfer volumes, supplier and recipient relationships, and temporal comparisons to previous five‑year periods, provides valuable insight into these evolving patterns. Its findings offer policymakers, defence planners, industry stakeholders, and analysts a comprehensive foundation for understanding how strategic imperatives are driving unprecedented changes in arms import behaviour and shaping the future of military capability development worldwide.
