Ukrainian forces destroyed dozens of Russian warplanes on Sunday in a coordinated drone strike that penetrated deep into Russian territory, hitting five military airfields and igniting aircraft, including strategic bombers and surveillance planes.

The operation, called “Spider’s Web,” took 18 months to plan and was personally overseen by President Volodymyr Zelensky, Ukraine’s security service (SBU) said.

Ukraine used small FPV drones hidden inside wooden cabins mounted on trucks. When the trucks reached their targets, the roofs opened by remote control, and the drones launched.

Videos on social media showed drones lifting off from parked trucks and striking large aircraft on the runways.

Ukraine says it will push for a full ceasefire, the return of captured prisoners, and the return of children taken to Russia. Those terms have not been agreed to by Russia.

The White House confirmed to Fox News that the Trump administration was not informed about the attack in advance. Secretary of Defense Pete Hegseth, who did not speak to Ukrainian officials immediately after the operation, was ultimately given a full briefing and subsequent updates, according to a senior defense official.

The officials said the blitz was highly sophisticated, and that the Pentagon is unsure whether the quadcopter drones, which were prepositioned in Russia in cabins and then offloaded into trucks, were piloted or autonomous.

U.S. officials were skeptical of reports that up to 50 Russian bombers were hit, and believed the number was likely between 11 and 15, the official said, who added it may have involved as many as five Russian airfields.

Military experts say the raid damaged Russia’s ability to launch long-range missile attacks. The bombers hit included TU-95 and TU-22M3 aircraft, which have been used in past strikes on Ukraine.

Ukraine also claimed it damaged a Russian A-50 radar aircraft, used to direct Russian air power.
