Ukrainian drone attacks remain the dominant driver of temporary suspensions at Moscow’s major airports, including Sheremetyevo, Vnukovo, Domodedovo, and Zhukovsky. In mid-June 2026, authorities imposed multiple flight restrictions over several days amid the largest reported drone assaults on the capital since the full-scale conflict began, with Russian air defenses intercepting dozens to hundreds of incoming drones and civil aviation bodies citing safety protocols. Additional closures occurred in May ahead of the Victory Day parade for security reasons, while July saw expanded airspace limits banning transit flights over the Moscow region until at least August due to ongoing threats. These patterns reflect repeated cause-and-effect responses where drone alerts trigger immediate ground stops, creating cascading delays without requiring permanent closures. Traders monitoring escalation signals, air defense activity, or official NOTAMs can assess near-term risks tied to these verifiable security measures.
