Russia has also started to launch fake drones, without any explosives, to confuse Ukraine’s air defence units and force them to waste ammunition. Compared to missiles they are much cheaper to build, easier to fire, and designed to sap morale.

Air-defense systems shot down 21 out of the 59 drones launched by Russia at targets in Ukraine early on November 14, the Ukrainian air force reported.

Russia attacked the Ukrainian capital Kyiv with a sophisticated combination of missiles and drones for the first time in 73 days on Wednesday, authorities said, as the Pentagon said most of the North Korean troops sent to help Moscow’s war effort are fighting to drive Ukraine’s army off Russian soil in the Kursk border region.

Ukraine's intelligence agency says the aircraft uses chips from Texas Instruments, Micron, STMicroelectronics, and others.

Electronic warfare-resilient drones and software integration will play a key role in the next phase of the Pentagon’s effort.

On the night of November 12, Russia launched a massive air attack on Ukraine, deploying 110 Shahed drones. Ukraine's air defense forces successfully destroyed 46 enemy targets, the Air Force of the Armed Forces of Ukraine reported.

Russia carried out several missile strikes and launched 110 drones against Ukraine on the night of 11-12 November: Ukraine's air defence downed 46 drones, 60 had disappeared from radar and 2 entered the Belarusian airspace.
