The U.S. believes Russia has not yet fully responded to Ukraine's Operation Spiderweb and may soon launch another large-scale, multi-pronged strike following the massive June 6 attack, Reuters reported on June 8, citing unnamed U.S. officials.
One official told Reuters that, while the timing remains unclear, a retaliatory strike could be expected in the coming days and is likely to be "asymmetrical." Another U.S. source said Russia would likely employ missiles and drones to hit a combination of targets.
The U.S. assessment follows the June 1 attack by Ukraine's Security Service (SBU) on four Russian air bases using drones launched from trucks concealed within Russian territory.
Kyiv's operation reportedly damaged 41 aircraft, including Tu-95 and Tu-22M3 bombers — two of Russia's primary platforms for missile attacks against Ukraine.
The Kyiv Independent could not independently verify the number of aircraft hit. At least 21 planes were damaged or destroyed, according to open-source intelligence analysts.
A Western diplomatic source told the outlet that the Kremlin's response could focus on high-value government sites, such as administrative buildings or intelligence facilities.
Michael Kofman, a military analyst with the Carnegie Endowment for International Peace, suggested Moscow may aim medium-range ballistic missiles at headquarters belonging to the SBU, which organized the operation.
On June 6, Russia launched one of its most intense aerial barrages of the full-scale war, firing 452 drones and 45 missiles at Ukrainian cities and infrastructure, according to the Air Force. The attack was likely part of Russia's response to Operation Spiderweb.
At least four civilians were killed, including emergency service workers, and 80 others were injured in the overnight assault, President Volodymyr Zelensky reported.
The June 6 strikes followed a phone call between Russian President Vladimir Putin and U.S. President Donald Trump on June 4, during which Putin reportedly vowed to retaliate against the Ukrainian drone operation.
U.S. officials say Moscow's June 6 barrage may not be the full extent of its response. Russia has carried out near-nightly air assaults in recent weeks, several of which predated Spiderweb, making it difficult to separate a targeted reprisal from Russia's ongoing campaign of attrition.
Shortly after the June 6 Russian attack, Trump seemed to justify the aggression against Ukrainian cities that was launched in response to Ukraine's Operation Spiderweb.
"They gave Putin a reason to go in and bomb the hell out of them last night," Trump told reporters aboard Air Force One on June 6.
