In Russia’s Long Drone Shadow

Carnegie Endowment for International Peace | Pavlo Zvenyhorodskyi

Russian long-range drone incursions into North Atlantic Treaty Organization airspace have expanded across Europe, testing allied defense readiness and public psychological resilience. In September 2025, approximately two dozen Russian drones crossed into Poland, forcing the temporary closure of four airports, including Warsaw Chopin Airport. Moscow now produces up to 400 long-range Geran-2 drones daily at $30,000 to $50,000 each.

Relying on expensive fighter jet missiles to intercept these low-cost systems threatens to rapidly deplete Western stockpiles. NATO launched Operation Eastern Sentry and announced the $40 billion Drone Edge initiative, while the European Union introduced the European Drone Defence Initiative. Interception capacity remains severely constrained. European responses suffer from institutional fragmentation and fail to build comprehensive public shelter infrastructure or emergency alert systems. European governments, backed by a €90 billion loan commitment for 2026–2027, must integrate Ukraine's battle-tested air defense architecture to establish effective long-term strategic deterrence.

Comment

The engagement of low-cost Geran-2 uncrewed aerial vehicles using Romanian F-16 fighter jets exposes a severe cost-exchange asymmetry in European NATO air defence. Flying multi-million-dollar tactical aircraft to launch missile interceptors against $30,000 long-range drones creates a financially unsustainable attrition rate for Western air arms. During routine air patrols under Operation Eastern Sentry, scrambling high-end jets consumes finite flight hours while burning through high-value guided munitions stockpiles.

This economic imbalance mirrors the 1944 V-1 flying bomb campaign over southern England, where initial fighter interception sorties rapidly exhausted RAF operational resources. British planners restored financial and material equilibrium only by shifting primary defence duties to automated radar-directed anti-aircraft artillery under Operation Diver. Consequently, NATO's current cost deficit against Russian drone saturation will persist until integrated short-range ground air defence systems replace fighter jet scrambles along the Eastern flank.

Strategic Question for Discussion

Which factor dictates the operational sustainability of NATO's Operation Eastern Sentry when confronting high-volume Geran-2 incursions — the financial cost-exchange ratio of missile interceptors or the airframe flight-hour depletion on frontline European fighter fleets?

The available evidence points toward airframe flight-hour exhaustion and interceptor inventory depletion as the immediate operational bottlenecks for NATO air defense forces. While budget allocations can eventually subsidize financial losses, manufacturing lead times for precision guided missiles and airframe maintenance cycles cannot match Russia's mass production of low-cost drones. My assessment is that the operational limits of frontline interceptor squadrons will force a rapid doctrinal transition toward ground-based short-range air defense systems.
