**Ukrainian long-range drone strikes targeting the Moscow region remain the dominant driver of repeated temporary flight restrictions at the capital’s major airports.** Russian authorities, through Rosaviatsiya, routinely impose safety-related limits on arrivals and departures at Sheremetyevo, Domodedovo, Vnukovo, and Zhukovsky when air-defense systems engage incoming UAVs, as confirmed in multiple August 2026 incidents. These measures enable interception operations and minimize risk to civilian aviation. Trader sentiment reflects the sustained pace of Ukrainian deep-strike activity, with notable barrages in mid-June, mid-to-late August (including around August 18–21 and 26), and associated closures or partial restrictions lasting hours. Recent events, such as drone waves coinciding with a U.S. official visit and ongoing infrastructure targeting, reinforce the pattern without clear signs of near-term de-escalation. No other factors, such as weather or unrelated regulatory actions, have produced comparable nationwide or multi-airport suspensions in the current period. Resolution hinges on official notices confirming simultaneous restrictions across the primary airports.
