Russian airports crippled by airspace threat canceled 171 flights in Moscow alone. Operations in five other cities were suspended entirely. The Russian Federal Air Transport Agency (Rosaviatsia) said that “external interference” disrupted airport functions. Authorities cited safety as the reason for halting air traffic. It is unclear, if the airports have been under a cyberattack or the agency just uses the vague language to describe Ukrainian drones in the airspace.

Sheremetyevo, Moscow’s main airport and Russia’s largest, suffered the largest collapse. As of 18:00 Moscow time on 6 July, 171 flights were canceled. Another 56 flights faced delays exceeding two hours, according to Rosaviatsia.

Around 15,000 passengers were preparing for departure at Sheremetyevo. They waited in crowded terminals as staff worked to stabilize operations.

St. Petersburg and Nizhny Novgorod airports crippled too

Pulkovo airport in St. Petersburg also faced major disruptions. According to Rosaviatsia, 90 flights were canceled and 37 delayed by over two hours.

Officials restricted access to the clean zone at Pulkovo. They aimed to reduce passenger congestion during the shutdown.

The Nizhny Novgorod Chkalov airport saw the most prolonged disruption. Authorities canceled 26 flights and delayed 13 others. Staff at Chkalov increased shift capacity to speed up boarding and baggage handling.

Smaller Russian cities halt airport activity completely

Airports in Ivanovo (Yuzhny), Kaluga (Grabtsevo), Pskov, and Tambov (Donskoye) stopped all flight services. Rosaviatsia said these closures were due to “periodic interference” from outside. All five airports had no incoming or outgoing flights. 

Authorities claim the situation is stable and controllable, use trains as fallback

Rosaviatsia claimed the situation was under control. The agency stated that Russia’s aviation system had “enough resources” to manage disruptions.

Russia’s Deputy Transport Minister Vladimir Poteshkin visited Sheremetyevo twice that day. He checked airline operations and crowd control measures.

Rail routes between major cities began to absorb stranded travelers. Authorities claimed over 8,000 train seats were available between St. Petersburg and Moscow from 6 to 8 July.

Explosions were reported in Moscow overnight on June 26, prompting airport closures, with Russia's Defense Ministry claiming 50 Ukrainian drones were downed across the country.

Moscow Mayor Sergey Sobyanin said emergency services were at the sites where two drones were downed.

According to the Shot Telegram channel, which appears to be close to Russian security forces, debris from a downed drone struck a residential building.

"Alarms went off everywhere," a local resident told the channel.

Ukraine's military regularly strikes military targets deep within Russia in an attempt to diminish Moscow's fighting power as it continues its war against Ukraine.

Russia's Defense Ministry later claimed 50 Ukrainian drones had been downed across the country, two of which were "flying towards Moscow."

The Kyiv Independent could not independently verify these claims.

Kaluga airport and Moscow's Vnukovo airport had flight restrictions imposed amid the drone attack, Artyom Korenyako, a spokesperson for Russia's state aviation agency Rosaviatsia, said early on June 26.

"The airport is temporarily not accepting or sending flights. Aircraft crews, air traffic controllers, and airport services must take all necessary measures to ensure flight safety," he said.

The restrictions were later lifted.

Putin insists the Russian economy is fine, but Kremlin officials say otherwise

In a rare public sign that all is not well in Russia, two high-ranking Moscow officials last week issued separate warnings about the state of the country’s economy. Russian Central Bank Governor Elvira Nabiullina and Economy Minister Maxim Reshetnikov both highlighted that amid the Kremlin’s full-scale war against Ukraine, the tools Moscow once relied on to maintain wartime growth are nearly exhausted. Almost immediately, Russian President Vladimir Putin on June 20 dismissed the concerns, clai

Ukrainian drones have forced at least 217 temporary airport closures across Russia since Jan. 1, independent Russian outlet Novaya Gazeta Europe reported on May 14, citing data from Russia's state aviation agency Rosaviatsia.

The figure already surpassed the combined total for all of 2023 and 2024, underscoring Kyiv's growing ability to put pressure on Russia, even in areas far from the border with Ukraine.

According to Serhii Bratchuk, spokesperson for the Ukrainian Defense Army's Southern Division, the surge in disruptions reflects a strategic shift in Ukraine's drone campaign.

"Moscow is the biggest aviation hub in the Russian Federation — flights go everywhere, not only across Russia, but worldwide," he told the Kyiv Independent last month.

"This is about the potential disintegration of Russian regions and the weakening of internal control."

Ukraine has also had remarkable success using first person view (FPV) drones — on June 1, Ukraine launched a game-changing drone attack on four key Russian military airfields, damaging 41 planes, including heavy bombers and rare A-50 spy planes.

Kyiv claimed it disabled 34% of Russia's strategic bomber fleet in what is seen as one of the most daring operations during Russia's full-scale war.
