The global defense industry reached another milestone in 2025, with major companies reporting record levels of business. However, a significant shift has emerged in the challenges facing Western defense sectors. Instead of insufficient government funding being the primary concern, manufacturing capacity and supply-chain constraints are increasingly becoming the biggest obstacles for many NATO members.
Defense companies across the United States and Europe benefited from a substantial increase in military spending on both sides of the Atlantic. In Europe, higher national defense budgets were accompanied by a growing role for the European Union in coordinating and financing collaborative procurement programs. Together, these developments created additional opportunities for defense contractors of all sizes.
The United States also committed substantial additional funding to defense procurement. The 2025 Reconciliation Act allocates the majority of its approximately $156 billion in military-related funding toward acquisition programs. This comes on top of an annual U.S. defense budget of around $900 billion.
However, the financial impact on defense contractors will not be immediate. Mark Cancian, a senior adviser with the defense analysis program at the Washington-based Center for Strategic and International Studies, noted that it could take several years for the newly authorized funds to reach companies and appear in their financial results. Nevertheless, he expects the additional spending to provide a significant boost to numerous defense manufacturers.
European defense companies are experiencing the effects of increased spending more directly. Following Russia’s full-scale invasion of Ukraine in February 2022, governments across Europe began substantially increasing their military budgets. That spending surge has continued to reshape the continent’s defense market.
European contractors are benefiting not only from the larger pool of government funding but also from a growing preference among European nations for domestically produced military equipment. Defense companies have consequently adjusted their strategies and expanded their capabilities to take advantage of this shift. At the same time, the sheer scale of new spending makes it difficult to determine how much market share European manufacturers have actually taken from major U.S. defense contractors.
Rising Defense Revenues Across the Industry
The latest Defense News Top 100 ranking provides clear evidence of the industry’s rapid expansion. The companies included in the ranking generated approximately $700 billion in defense-related revenue, compared with $629 billion the previous year. That represents an increase of about 11.3%.
U.S. companies continue to dominate the highest positions in the ranking. Lockheed Martin retained the number-one position, recording $72.1 billion in defense revenue. RTX followed with $46 billion, while General Dynamics reported $39.4 billion and Northrop Grumman generated $37 billion.
BAE Systems, headquartered in the United Kingdom but with a substantial presence in the United States, remained the highest-ranked company outside the U.S. The company moved up one position to fifth place, reporting approximately $36 billion in defense revenue.
Boeing’s defense business also improved its position, rising to sixth place with $35.7 billion in revenue. L3Harris likewise advanced in the rankings, reaching eighth place with $17.4 billion.
Between BAE Systems and Boeing sits China’s Aviation Industry Corporation of China, which reported approximately $32.3 billion in defense revenue.
The figures highlight how rapidly defense spending is translating into increased revenues for major contractors, while also underscoring the growing challenge of expanding production capacity quickly enough to meet rising demand.
