KYIV, Ukraine — Ukraine’s air force claimed Saturday to have downed a Russian hypersonic missile over Kyiv using newly acquired American Patriot air defense systems, the first known time the country has been able to intercept one of Moscow’s most modern missiles.
Mykola Oleshchuk, the head of Ukraine’s air command, said in a Telegram post that the Kinzhal-type ballistic missile had been intercepted in an overnight attack on the Ukrainian capital earlier in the week. It was also the first time Ukraine is known to have used Patriot defense systems.
“Yes, we shot down the ‘unique’ Kinzhal,” Oleshchuk wrote. “It happened during the night time attack on May 4 in the skies of the Kyiv region.”
Oleshchuk said the Kh-47 missile was launched by a MiG-31K aircraft from the Russian territory and was shot down with a Patriot missile.
The Kinzhal is one of the latest and most advanced Russian weapons. The Russian military says the air-launched ballistic missile has a range of up to 1,250 miles and flies at 10 times the speed of sound, making it hard to intercept.
A combination of hypersonic speed and a heavy warhead allows the Kinzhal to destroy heavily fortified targets, like underground bunkers or mountain tunnels.
The Ukrainian military has previously admitted lacking assets to intercept the Kinzhals.
“They were saying that the Patriot is an outdated American weapon, and Russian weapons are the best in the world,” air force spokesman Yurii Ihnat said on Ukraine’s Channel 24 television. “Well, there is confirmation that it effectively works against even a super hypersonic missile.” Ihnat said.
He said successfully intercepting the Kinzhal is “a slap in the face for Russia.”
Ukraine took its first delivery of Patriot missiles in late April. It has not specified how many of the systems it has or where they have been deployed, but they are known to have been provided by the United States, Germany and the Netherlands.
Germany and the U.S. have acknowledged each sending at least one system and the Netherlands has said it has provided two though it is not clear how many are currently in operation.
Ukrainian troops have received the extensive training needed to be able to effectively locate a target with the systems, lock on with radar and fire. Each battery requires up to 90 personnel to operate and maintain.
Defense Minister Oleksii Reznikov said he first asked for Patriot systems when visiting the U.S. in August 2021, months before Russia’s full-scale invasion but seven years after Russia illegally annexed Ukraine’s Crimea peninsula.
He has described possessing the system as “a dream” but said he was told in the U.S. at the time that it was impossible.
The Patriot was first deployed by the U.S. in the 1980s. The system costs approximately $4 million per missile, and the launchers cost about $10 million each, according to analysts.
At such a cost, it was widely thought that Ukraine would only use the Patriots against Russian aircraft or hypersonic missiles.
In a Telegram post on Saturday, Valerii Zaluzhnyi, the commander-in-chief of Ukraine’s armed forces, said he had thanked U.S. Gen. Mark Milley, the chairman of the Joint Chiefs of Staff, for the ongoing American aid to Ukraine.
Zaluzhnyi said he also briefed Milley “about the situation at the front and preparations” for Ukraine’s counteroffensive against Russia.
Ukraine has not said when it might launch the counteroffensive, but it is widely anticipated this spring.
In an interview this week with Foreign Affairs magazine, Milley said he would not speculate on if or when it might come, but that with NATO assistance to help train and equip nine brigades’ worth of combined arms, armor and mechanized infantry, “the Ukrainians right now have the capability to attack.”
He also said that their capability to defend was “significantly enhanced from what they were just a year ago.”
“I don’t want to suggest that they may or may not conduct an offensive operation in the coming weeks,” he said. “That’ll be up to them. They’ve got a significant amount of planning and coordination and all of that to do, if they were to do an offensive operation. But they’re prepared to do offense or defense.”
In other developments, officials in both Russia and Ukraine said they had carried out another of their regular exchanges of prisoners of war.
The Russian defense ministry said it brought three military pilots back to Russia, and Ukrainian President Volodymyr Zelenskyy’s chief of staff, Andriy Yermak, said 45 fighters who defended the Azovstal steel mill in Mariupol had been returned to Ukraine.
Also on Saturday, Ukraine’s Special Operations Forces accused Russia of using phosphorous munitions in its attempt to wrest control of the eastern city of Bakhmut from Ukrainian forces.
Russian troops have been trying to take the city for more than nine months, but Ukrainian forces are still clinging to positions on the western edge of the city.
On Saturday, the Ukrainska Pravda newspaper quoted military officials as saying that “the enemy used phosphorus and incendiary ammunition in Bakhmut in an attempt to wipe the city off the face of the earth.”
A photo accompanying the newspaper report showed an urban area lit up with fire in multiple places.
The allegations could not be independently verified.
Russian forces have not commented on the claim but have rejected previous accusations from Ukraine that they had used phosphorus.
International law prohibits the use of white phosphorus or other incendiary weapons — munitions designed to set fire to objects or cause burn injuries — in areas where there could be concentrations of civilians.
White phosphorous can also be used for illumination or to create smoke screens.
