Drone walls as air defense

Britain plans to mass‑produce drones to build a 'drone wall' shielding NATO’s eastern flank from Russian jets. This signals a doctrinal pivot from manned interceptors and legacy SAMs toward layered, swarming UAV defenses that fuse sensors, autonomy, and cheap munitions. — If major powers adopt 'drone walls,' procurement, alliance planning, and arms‑control debates will reorient around UAV swarms and dual‑use tech supply chains.
