Ukrainian long-range drones targeting Russian facilities along the Baltic Sea have repeatedly crossed into the airspace of Estonia, Latvia, and Lithuania (three former Soviet republics that joined NATO in 2004), with at least half a dozen incursions recorded in a single week. Baltic officials, including Latvian Foreign Minister Baiba Braze, say Russian electronic warfare is misdirecting the drones off course, while acknowledging NATO currently lacks unified counterdrone defences along its eastern flank. The incidents highlight a growing vulnerability for the alliance, which is still reliant on costly interceptor missiles and scrambled jets to neutralise cheap drones — a gap NATO is now racing to close by drawing on battlefield lessons from Ukraine.
