President Volodymyr Zelensky sent an urgent letter to US President Donald Trump warning that Ukraine is facing a worsening shortage of air defense systems, particularly anti-ballistic missile capabilities, according to a report on Wednesday, May 27.
According to the Kyiv Independent, the letter warns that Ukraine’s current stockpile of Patriot interceptors and other Western-provided air defense systems may not be sufficient to withstand escalating Russian missile attacks.
“When it comes to defending against ballistic missiles, we rely almost exclusively on the United States.”
The appeal comes as Russia intensifies large-scale aerial bombardments across Ukraine and publicly threatens new long-range strikes against Kyiv, including attacks on what Moscow described as Ukraine’s “decision-making centers.”
According to the Kyiv Independent, Ukraine’s Ambassador to the United States Olha Stefanishyna has been distributing the letter to the White House, House Speaker Mike Johnson and members of Congress.
The letter also reportedly expresses concern over delays in weapons deliveries through the Prioritized Ukraine Requirements List (PURL) program, which allows NATO allies to finance purchases of US-made weapons for Ukraine.
“The current pace of deliveries through the PURL program is no longer keeping up with the reality of the threat we face,” the letter says.
“I ask for your help in protecting Ukraine’s skies from Russian missiles.”
Presidential Office confirms letter
Ukraine’s Presidential Office later confirmed that Zelensky had sent the appeal to both Trump and the US Congress.
“Yes, it’s true. [He wrote] to the president of the United States and Congress – there were two recipients,” presidential adviser Dmytro Lytvyn told journalists, according to Liga.net.
The letter reportedly asks Washington to remain engaged in supporting Ukraine’s air defense needs, specifically requesting additional Patriot PAC-3 missiles and systems.
“I, on behalf of the Ukrainian people, respectfully ask the president and the US Congress to remain engaged,” Zelensky wrote, according to the report.
“And to help us secure this vital tool of protection against Russian terror.”
Later, the full text of the letter was published on X by Axios journalist Barak Ravid.
After a major attack on Kyiv and the Kyiv region on May 24, Russia’s Foreign Ministry on Monday announced the start of what it called “systematic strikes” on Ukraine’s military-industrial facilities and “decision-making centers” in Kyiv. At the same time, Moscow urged foreign nationals and diplomatic staff to evacuate the city.
EU Ambassador to Ukraine Katarina Mathernova rejected the Russian warnings, insisting Western diplomatic missions would remain in Kyiv despite growing threats.
China also commented on Moscow’s threats, urging all sides to avoid further escalation while refusing to clarify whether it planned to evacuate embassy staff from Kyiv.
On Monday Zelensky said Ukraine continues discussions with international partners over additional air defense systems.
He said anti-ballistic systems are currently in global shortage because of the war involving Iran.
“We are working with all our partners regarding air defense for Ukraine – it is clear this is the number one priority,” Zelensky said.
“And anti-ballistic systems are now in global deficit because of the war with Iran.”
According to the president, Ukraine recently discussed air defense cooperation with French President Emmanuel Macron, Norwegian Prime Minister Jonas Gahr Støre, and Finnish President Alexander Stubb.
Zelensky also said Kyiv is trying to accelerate anti-ballistic missile production in Europe while continuing talks with the United States on additional support.
