Russia’s Shift to Training Missiles Strains Ukraine’s Air Defenses

The RM48U, originally engineered as a target for S-400 systems, lacks the accuracy of the Iskander ballistic missile. With an average deviation of roughly 300 meters, the weapon relies on volume rather than precision to inflict damage. Investigators linked these missiles to a recent strike on a suburban railway platform near Kyiv that left eight people dead, highlighting the lethal consequences of Russia's strategy of attrition. Military analysts at the Royal United Services Institute suggest Moscow is using these abundant, less sophisticated systems to force Ukraine into a difficult choice: expend scarce Patriot interceptors on lower-priority threats or risk significant collateral damage.

Strategic constraints and supply

This adaptation reflects Russia’s broader industrial limitations. While Moscow can produce roughly 750 Iskanders annually, production constraints on solid rocket motors have incentivized the use of alternatives. Meanwhile, Ukraine faces a critical shortage of interceptors, a vulnerability exacerbated by global demand for Patriot systems. President Volodymyr Zelenskiy has repeatedly signaled that the lack of advanced air defense munitions is directly impacting civilian safety. As winter approaches, this dynamic of trading quantity for quality threatens to further degrade Ukraine’s energy infrastructure, forcing Kyiv to prioritize the replenishment of interceptors alongside its offensive requirements.
