The declaration matters because industrial capacity is now the decisive variable in an artillery-centric war. Europe’s Act in Support of Ammunition Production is pushing shell capacity toward two million rounds per year by the end of 2025, while the United States has opened new automated “Universal Artillery Projectile Lines” in Mesquite, Texas, and added a 155 mm load-assemble-pack facility in Camden, Arkansas. Washington admits the 100,000-per-month target will slip into 2026, but the trajectory is unmistakable. The effect is to ease Ukrainian rationing, narrow Russia’s daily fires advantage, and restore deterrence by signaling that NATO magazines will refill faster than the Kremlin can deplete them.
