Russia responded to Ukrainian Armed Forces offensive with new drones, they are used first time

Ukrainian offensive in Kursk region succeeded thanks to electronic warfare blitz that "blinded" Russian reconnaissance drones. Russia responds with drones immune to jamming.
As Forbes writes, this is the first time such a weapon has been used on the battlefield, and also a kind of warning for most countries that rely heavily on jamming to protect themselves from terrorist drone attacks.
FPV drones need radio communication with the operator, so on the front line you can see many jammers that knock out radio noise on selected frequencies. Effective electronic warfare means create a "safe bubble" in the region of 50-100 meters, so UAVs constantly change operating frequencies, and the jammers themselves are updated.
"That's why a blitz attack like Kursk is needed, with a long lead time to detect all frequencies and enough jamming to block everything in the area and stop all drones for a while," the journalists explain.
Radio communication requires line of sight, and during the attack itself, the drones dive quite low, so at the last second, interference appears in the video signal, which impairs visibility.
"One solution to the jamming problem is terminal guidance using artificial intelligence: the operator locks on a target at a certain distance, and the drone pursues it even if communication is lost. These systems are already being deployed in small numbers by both sides. Another approach is wire guidance: the drone reels in a fiber optic cable as it moves, similar to wire-guided missiles like the TOW," the article says.
Ukraine recorded a Russian prototype of a fiber-optic drone back in March, and recently Russian Telegram channels showed footage of the use of Prince Vandal Novgorodsky drones in the Kursk region. They are said to be immune to electronic warfare.
