Ukraine has asked the EU to spend billions from its support loan on Patriot air-defense missiles, a request European Commission President Ursula von der Leyen confirmed the bloc is weighing. How far the money would stretch depends on a price only Washington controls.

Russia keeps firing more ballistic missiles at Ukrainian cities than the country can shoot down, the warheads hardest for its air defenses to stop. Only a US-made Patriot system can catch them, and their interceptors remain in short supply worldwide, so who pays for them and Washington that agrees or disagrees to sell them now shapes how many cities stay covered.

The exemption Kyiv needs

The European Commission has already received a payment request covering Ukraine's air defenses, including the PAC-3 interceptors that arm Patriot systems. Von der Leyen put it at "several billion euros" and said member states were reviewing it, without naming a figure.

Suspilne, citing its own sources, reported that the request seeks just over $2.3 billion, with another $4.6 billion from the loan's defense tranche going to arms manufactured in Ukraine and the EU, mostly drones.

The money would come from the EU's $104 billion support loan for 2026–27. Because PAC-3 is US technology, spending loan money on it needs an EU exemption. National representatives will take up the decision on 7 September.

What the money actually buys

Defense Express has calculated how many interceptor missiles Ukraine can get with the loan. At the $4–5 million per round the US Army pays, $2.3 billion would fund 460-580 interceptors. At the $6.61 million export price Germany paid in late 2024, about 315. At up to $12.3 million each, the US cleared for Saudi Arabia on 30 January 2026, just 190.

Why money isn't the real problem

For Ukraine, the harder question is not price but whether it can get the missiles at all. Even 315 rounds would equal about half the world's current yearly output, which the sole producer, Lockheed Martin, is straining to lift from around 600 a year to 2,000 by 2030.

Kyiv has been short of interceptors for months. In August, Zelenskyy said Ukraine reached a deal with the US for monthly Patriot deliveries, but that it still needs at least around 5% of American output to get through winter. EU Foreign Policy Chief Kaja Kallas has urged member states to hand over interceptors, especially those with shelf lives nearing their end.

Russian President Vladimir Putin said Moscow would “find a way to respond” if civilian “tragedies” followed President Volodymyr Zelenskyy’s warning that Ukrainian drone operations were making Russian skies unsafe. Zelenskyy told foreign airlines and insurers that the “safe moments” in Russian airspace were over.

Zelenskyy’s warning seeks to extend the cost of Russia’s war beyond damaged military and energy facilities to airlines, insurers, and travelers. It does not mean Russian airspace is legally or completely closed. However, carriers that continue flying over Russia face higher costs from repeated airport shutdowns during drone alerts, as well as the danger that military activity in Russian airspace could endanger civilian aircraft.

Putin spoke after a 1 September Shanghai Cooperation Organization summit in Bishkek, where Russia and China coordinate regional security. Zelenskyy’s warning amounted to “a bid for state terrorism” if he had made it publicly, the Russian president said, adding that Russia does not negotiate with “terrorists.” Putin also said Russian forces were preparing massive strikes on Ukraine’s energy infrastructure.

In his evening video address, Zelenskyy said Ukraine did not threaten civilian aircraft but would keep striking Russian military targets and parts of the economy supporting the war. Ukraine’s Presidential Office head Kyrylo Budanov backed the decision, saying long-range weapons would systematically strike military targets in Russia while the invasion continued.

Shares in Aeroflot, Russia’s national airline, fell to an intraday low of 30.36 rubles at about 20:40 Moscow time, down 5.11%, Meduza reported, citing Moscow Exchange data. The timing does not establish that Zelenskyy’s speech alone drove the decline.

Wall Street Journal correspondent Yaroslav Trofimov posted a chart of the decline on X, writing, “Aeroflot shares after Zelensky’s warning.”

European and US carriers already avoid Russian airspace, but airlines from China, Türkiye, the United Arab Emirates, and other Gulf states continue using it, Reuters reported. Aviation-risk firm Osprey Flight Solutions assessed that daily attacks deep inside Russia were nearly certain through 2026 and warned of possible misidentification.

Andrii Kovalenko, head of Ukraine’s Center for Countering Disinformation, said it was “strange” to hear terrorism accusations from “the leader of a terrorist organization masquerading as the Russian state.” Putin’s reaction showed Moscow feared pressure on its airspace, he argued.

Previous closures of Russian airspace due to Ukrainian attacks

Russian airports were repeatedly shut during Ukrainian drone alerts well before Zelenskyy’s warning. On 6 July 2025, Moscow airports canceled 171 flights while airports in five other cities suspended operations.

A 27 May attack closed airports serving Moscow and several other cities after Russia claimed it intercepted 99 drones. Another wave caused flight disruption and mobile internet outages around Moscow, while a 29 May alert again halted flights at Moscow airports.

More recently, Russian authorities restricted operations at Moscow airports during Ukrainian drone attacks, delaying more than 450 flights
