NATO's Eastern Shield Faces Modern Drone Warfare Challenges

NATO's Eastern Shield faces significant challenges against modern drone warfare, according to a new whitepaper by the Center for Strategic and International Studies (CSIS). The report, 'Building Counter-UAS into NATO's Eastern Shield', warns that current defences have critical gaps and are insufficient against drone threats.

Drones are increasingly the first line of attack in incursions, as seen in recent sightings that shut down airports in Copenhagen and Oslo. The whitepaper recommends a layered detect-decide-defeat chain, prioritising low-cost effectors to address this growing threat. Currently, once drones cross the initial radar line, interception relies solely on expensive and scarce fighter jets.

To improve NATO's defences, the whitepaper calls for integrated NATO-wide command-and-control systems. These systems would enable rapid triage and cross-border coordination, filling radar blind spots and addressing cost imbalances. The goal is a layered defence system delivering coverage, speed, and cost discipline.

The CSIS whitepaper, 'Building Counter-UAS into NATO's Eastern Shield', highlights the urgent need for NATO to strengthen its defences against drone warfare. By integrating airborne counter-UAS capabilities and improving command-and-control systems, NATO can close critical gaps and better protect its airspace.
