The European Union is grappling with significant defense challenges, driven by insufficient arms production and a strategic reliance on the United States. A 2023 report from the National Assembly's defense committee highlighted that France's existing weapons stockpiles would last only a few weeks in a high-intensity conflict. More recently, a 2025 projection by the French Institute of International Relations (Ifri) estimated that the French air force, despite its technological edge, would last just three days in such a scenario due to "significant vulnerabilities." European armies are not lacking in tanks, ships, or aircraft, as they are generally on par with Russia and often outperform it with advanced technology. Soldiers are well-trained and equipped with modern gear, according to Philippe Gros, a researcher at the Foundation for Strategic Research. However, the real issue lies elsewhere. "We have a little of everything... and a lot of nothing," he notes, emphasizing the gaps in critical areas. One major hurdle is logistics. "It has been calibrated to the minimum for decades," says Gros. The shortage of ammunition is particularly concerning. While Ukraine can fire up to 8,000 155 mm shells per day, France produced an average of only 500 per year between 2012 and 2017. It wasn't until 2024 that the French Ministry of the Armed Forces increased production targets to 100,000 annually. European armies also lack the necessary trucks, planes, and medical support to sustain operations, and they remain heavily dependent on the United States for intelligence, air defense, and electronic warfare capabilities. The European defense industry faces another challenge: fragmentation. There are six tank manufacturers and three aircraft engine producers across the continent, making it difficult to achieve the scale needed for new production. "If orders are scattered, no industrialist will be able to reach the critical mass necessary to make a new factory profitable," argues Maxime Cordet. To address this, European countries are exploring joint purchases and shared production, such as the €60 million allocated for 1,500 Mistral missiles made by nine European nations. These collaborative efforts aim to reduce costs and increase production efficiency. Despite these efforts, the path to a unified European defense sector remains fraught with political and logistical challenges. While the European Commission and individual nations are pushing for greater cooperation, national interests often take precedence. This has led to delays and inefficiencies in major projects like the Franco-German tank program and the A400M transport aircraft. Meanwhile, countries like Poland are opting for foreign arms purchases, and European forces continue to rely heavily on American equipment, raising concerns about technological sovereignty and potential risks of American control over critical military systems.
