“High-end missile interceptors can run into the millions of dollars per shot.
Many of the drones they are designed to defeat are far cheaper and produced in large numbers — creating what defense officials have described as a growing “math problem” in modern warfare. The U.S. can end up firing expensive missiles at relatively inexpensive drones, a dynamic that becomes harder to sustain if attacks come in waves.
That imbalance is accelerating a push inside the Pentagon to expand a layered counter-drone strategy — combining short-range interceptors, electronic warfare tools and emerging technologies such as high-energy lasers.
For U.S. forces in the region, larger drone waves increase the odds that defenses are stretched, and that even one drone could reach a base or ship.
This marks the first sustained confrontation in which U.S. forces are facing large-scale, state-backed drone waves as a central feature of the battlefield — forcing commanders to adapt in real time and draw on lessons learned from Ukraine, where mass-produced Shahed drones reshaped air defense strategy.”
