Christian Brose is the president and chief strategy officer at Anduril Industries (the American defense technology company that builds advanced military systems using artificial intelligence, robotics, and software-driven platforms). He’s also the author of The Kill Chain. In this interview, he argues that despite massive defense spending, the United States is dangerously unprepared for a prolonged, high-intensity war, having built a military optimized for short conflicts with expensive, hard-to-replace weapons rather than sustained attrition. He explains how decades of procurement choices, limited industrial capacity, and lack of competition have left munitions stockpiles thin, while emerging conflicts in Ukraine and the Middle East highlight the growing importance of mass, low-cost, and autonomous systems. The conversation explores the need for a new “high-low mix” of capabilities, the transformative but still cautious role of AI in warfare, and the strategic challenge posed by China’s industrial model, ultimately concluding that the core issue is not just process but leadership—the willingness to rethink assumptions and rapidly adapt to the changing character of war.
