Russian MoD stated that 39 drones were destroyed by air defence at night:

▪️19 drones — Kursk region;
▪️9 drones — Belgorod region;
▪️5 drones — Bryansk region;
▪️3 drones — Voronezh region;
▪️3 drones — Leningrad region;
▪️2 drones — Oryol region.

But several drones went through and hit targets.
The amount of drones from Ukraine increases sharply. While Ukraine did not use drones to attack Russian infrastructure at the beginning of the war, at the beginning of 2023 there were only a few drones per night. Now there are around 50 drones used at the same time.

Russia has therefore increased protective measures since this year, including "drone nets" around gas power plants.
