The Theatre Competition for Critical Munitions
How U.S. Stockpile Constraints Are Reshaping Europe’s Defence-Industrial Opportunity
The central problem is no longer whether the United States possesses enough military power to sustain deterrence, but whether the same limited basket of high-demand missiles and interceptors can be allocated across several theatres at once. Ukraine, Israel, the Red Sea, the Gulf and the Indo-Pacific now draw on overlapping categories of standoff weapons, air-defence interceptors, missile-defence systems and counter-drone capabilities. This creates a structural tension between present operations and future contingencies, especially in a Taiwan scenario, where long-range strike, maritime strike and air-and-missile defence inventories would become decisive. The issue is therefore not a generic shortage of munitions, but a theatre-allocation problem inside an industrial system constrained by long production cycles, fragile subtier suppliers, solid rocket motors, energetics, microelectronics and critical materials.
The report is structured around the full chain linking operational demand to industrial consequence. It first defines the contested munitions basket and explains why Iran, Ukraine and Taiwan expose the same underlying stockpile problem. It then examines the U.S. industrial base, showing why additional funding does not automatically translate into rapid missile output. The analysis then shifts to Europe, assessing where European industry can partially substitute, localise or reinforce capacity through MBDA, Eurosam, SAMP/T NG, Aster, Diehl, IRIS-T, COMLOG, Patriot GEM-T production in Germany and wider European supply-chain actors. The final sections connect these industrial shifts to EU regulatory instruments, critical raw materials, defence semiconductors, European defence expenditure, investor exposure and three scenarios for 2026–2030.
