This was stated by Vadym Skibitskyi, a representative of the Defence Intelligence of Ukraine, in an interview with RBK-Ukraine news agency.

“They really have problems with their arsenal, including drones. To date, they have used approximately 660 Shahed drones. The contract provides for 1,750 units. It takes time to deliver and prepare them. They [russians] have used a large amount in recent days, and these reserves need to be replenished. According to our data, they will now get another shipment. We will clarify the quantity. As a rule, before that, 250-300 pieces were brought in a batch. Let's see how it will be this time,” Vadym Skibitskyi stressed.

Commenting the question about the launching of drones in mass, he noted that a massive drone attack is aimed at breaking through our air defence system and hitting facilities. Launching a small group – 5-10 units – will not produce such an effect.

The representative of Ukraine's military intelligence added that the russians are using different altitudes and different directions to bypass air defence systems, as well as changing drone launch areas.
