In a single week in September 2024, Russia dropped more than 900 glide bombs along its 800-mile front line with Ukraine, according to Ukrainian estimates.

Ukraine was almost powerless to stop the long-range weapons – and the consequences were devastating.

Known as Russia’s “miracle weapon”, glide bombs would routinely be used to wipe out key Ukrainian targets, from logistics bases to army headquarters. Fitted with wings and satellite-aided navigation, each weighed as much as three tons.

However, 12 months later, Russia’s glide bombs are effectively useless, owing to the sudden success of Ukrainian radio jammers.

Fighterbomber, a Telegram channel run by an anonymous Russian pilot, said Ukrainian jammers had “saturated the front line”, blocking the glide bombs’ internal navigation systems.

“All satellite-guided correction systems have left the chat,” the pilot said.
