In an interview with RBC-Ukraine, the representative of the Main Intelligence Directorate of the Ministry of Defense of Ukraine, Vadym Skibitsky, said this.

"They really have problems with their arsenal, including drones. To date, they have used approximately 660 drones. The contract provides for 1,750. It takes time for their delivery and preparation. They have used a large amount recently, and these stocks need to be replenished," Vadym Skibitsky emphasized.

Commenting on the issue of launching swarms of drones, he noted that a massive swarm of drones is aimed at breaking through our air defense system and hitting targets. If you run a small amount - 5-10 - there will be no such effect.

The representative of military intelligence of Ukraine added that the Russians use different directions to bypass air defenses, and also change the areas of launching drones.

"According to our data, they (Russians) will now have another delivery batch. How long will it be - we will clarify. As a rule, they brought in batches of 250-300 pieces before that. Let's see how it will be this time."
