Ukraine intelligence reports that Russia is expending air-defense interceptor missiles “at an unsustainable rate,” driven in part by stepped-up Ukrainian drone strikes. According to the accounts, the increased volume and impact of drone attacks are forcing Russia to respond more frequently, which can lead to interceptor consumption that outpaces production or replenishment.

The reporting characterizes the assessment as based on intelligence evaluations rather than independently verified battlefield inventory counts. It also notes that the situation could reflect both Russia’s operational decisions—such as how often it chooses to intercept drones—and the practical limits of its supply chain for producing and deploying additional missiles.

While the sources describe concern that Russia may be burning through its stock faster than it can rebuild, they do not provide a definitive measurement of remaining inventories. The claims are presented as an intelligence-based indication of strain on Russia’s air-defense resources as Ukrainian attacks intensify.
