- Russia said it transferred a Matek H743 flight controller and routing data from an alleged Ukrainian drone attack on Putin’s Valdai residence to a U.S. military attache.
- U.S. intelligence agencies assessed that Ukraine did not attempt the attack, while Russian officials issued conflicting claims on the number of drones involved.
Russia’s Ministry of Defense said on Thursday, January 1, that it handed over decrypted routing data and a flight controller from what it claims was a Ukrainian unmanned aerial vehicle involved in an alleged attack on President Vladimir Putin’s residence near Lake Valdai to a representative of the U.S. embassy’s military attache office.
According to a statement from the Ministry of Defense of the Russian Federation, the materials were presented during a meeting between Admiral Igor Kostyukov, head of the Main Intelligence Directorate of the Russian General Staff, and a U.S. military attache representative. The ministry said the recovered drone components included navigation systems that remained technically operational.
“I invited you on an important matter. We want to inform you that we found fragments of unmanned aerial vehicles that carried out this attack. In several of these unmanned aerial vehicles, the navigation systems were well preserved and are technically operational,” Kostyukov said, according to video footage released by the ministry.
The presented flight controller was a Matek H743, a Chinese-made component widely available on the commercial market. The controller is commonly used on small reconnaissance or light strike drones with operational ranges of up to approximately 150 kilometers and is not restricted for military use.
The alleged target of the attack, a residence known as “Dolgye Borody” located on Lake Valdai in Russia’s Novgorod region, lies more than 850 kilometers from Ukrainian-controlled territory. Platforms typically used by Ukraine for deep-strike missions at such distances include heavier long-range drones such as the Lyutyi An-196 and FP-1, which are known to be equipped with more advanced and redundant flight control systems, including Cube Orange+ controllers. The use of such controllers has been documented in multiple publicly available photographs from crash sites of long-range drones inside Russia.
The presentation of a Matek H743 controller as evidence therefore prompted skepticism among observers, given the technical mismatch between the controller’s typical use case and the claimed flight distance to Valdai. Russian authorities did not provide additional technical documentation linking the controller to a long-range strike platform.
U.S. media outlets reported that American intelligence agencies reached a different conclusion regarding the alleged incident. The Central Intelligence Agency and the National Security Agency assessed that Ukraine did not attempt to attack Putin’s residence, according to sources cited by The Wall Street Journal and CNN.
CNN reported that on December 31, CIA Director John Ratcliffe briefed U.S. President Donald Trump on the intelligence community’s findings. The report said the agencies concluded that the incident described by Russian officials was not the result of a Ukrainian drone attack.
On the same day, Trump shared a link on his Truth Social account to an editorial published by the New York Post, which linked Russia’s public claims about the alleged attack to broader political messaging surrounding the war in Ukraine.
Russian officials have also issued conflicting statements about the scale of the alleged attack. Foreign Minister Sergey Lavrov initially claimed that 91 drones were involved, while the Defense Ministry later reduced the figure to 31 drones. No explanation for the discrepancy was provided.
