All Western partners from the group of specialists who assisted in obtaining and processing satellite reconnaissance data at the military headquarters in Kyiv have left Ukraine. This was reported by the American magazine Time, citing a source close to the General Staff of Ukraine.

The decision by U.S. President Donald Trump’s administration to cut off Ukraine’s access to satellite imagery while the country defends itself against Russian military aggression has helped Russia advance in a critical sector of the front, weakening the negotiating position of Ukrainian President Volodymyr Zelensky. The decision, made earlier this week, has directly led to significant losses among Ukraine’s Armed Forces in recent days, according to five senior Western and Ukrainian officials and military personnel familiar with the situation, Time reports.

"As a result of this pause, hundreds of Ukrainians have died," a Ukrainian officer told the magazine. "This truly gives the enemy an advantage on the front line." He added that Ukrainian forces are now fighting without some of their key weapons systems not because of intensified Russian attacks, but because of 'America retreating' from its commitments."

The impact on Ukraine was felt most acutely in Russia’s Kursk region, where Ukrainian forces have struggled to hold onto a strip of territory they seized in August 2024, Time writes. Zelensky considers this region a critical bargaining chip for any future territorial negotiations with Russia. However, since the U.S. cut off intelligence-sharing, Russian forces, supported by North Korean troops, have quickly advanced in the Kursk region, aiming to cut off Ukraine’s supply lines in the area, according to the latest battlefield maps compiled by the Ukrainian OSINT project Deep State.

A source in the Ukrainian government confirmed to Time that operations in the Kursk region have suffered the most due to the loss of U.S. intelligence access since Ukraine can no longer detect approaching Russian bombers and other combat aircraft taking off from Russian territory. As a result, the military now has far less time to warn civilians and soldiers about the risk of incoming Russian airstrikes or missile launches.

"This is extremely dangerous for our people," the government source emphasized. "It must be changed immediately."

In addition, the loss of U.S. satellite reconnaissance data has also harmed Ukraine’s ability to conduct long- and medium-range strikes against Russian targets, the source added.

The American company Maxar Technologies has cut off Ukraine’s access to its satellite imagery, citing an "administrative request." However, the real reason behind this move is the U.S. administration’s ban on providing Ukraine with intelligence data, according to the Ukrainian defense outlet Militarnyi, which cited several users of the service.

Maxar is one of the leading providers of commercial satellite images that were used to track Russian troop movements and assess the damage from strikes on targets in Ukraine and Russia.

Previously, it was reported that the Trump administration had banned the transfer of U.S. intelligence data to Ukraine. CIA Director John Ratcliffe confirmed this information to the media. The New York Times, citing a source, clarified that Kyiv is no longer receiving targeting information, making it more difficult to strike Russian forces.

At the same time, Ukraine still has access to other satellite imagery, the report notes. The decision came two days after Trump ordered a halt to military and humanitarian aid to Ukraine amid a controversy involving President Zelensky at the White House on February 28.
