The barrage included 407 drones and 44 ballistic and cruise missiles, Ukrainian air force spokesperson Yurii Ihnat said.

Ukraine said its “Operation Spiderweb” attacked Russian warplanes worth hundreds of millions of dollars, utilizing drones that each cost under $1,000 and were launched from wooden containers carried on trucks.

Ukrainian forces struck multiple Russian airfields and military facilities overnight on June 6, hours before Russia launched one of its heaviest aerial assaults of the war, the General Staff of Ukraine's Armed Forces reported.
