Solid rocket motor stockpiles are tightening just as missile-defense demand accelerates, exposing a supply chain that cannot scale fast enough. CSIS used a June 12 rollout of its missile-defense report to frame SRMs and their subcomponents as the bottleneck in interceptor output, arguing that the industrial base needs broader capacity, more qualified sources, and less reliance on a narrow supplier set.
The pressure runs through Patriot, THAAD, and related air and missile defense systems, where motor availability governs how quickly inventories can be rebuilt after recent operational drawdowns. The policy signal is clear: the sector now faces a race between replenishment and another demand spike.
