Drones are “ubiquitous, because they are quite useful, and they're demonstrating that every day in Ukraine,” one analyst told NBC News.

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.

The attack targeted almost all Ukraine, with nine regions affected, including Kyiv, Lviv, and Sumy. Ukrainian President Volodymyr Zelensky described it as one of the largest attacks since the war began.
