Ukraine has deployed an upgraded version of its Lima jamming system, called Lima Quant, that is reportedly able to neutralize Russia's deadly guided glide bombs known as KABs. The new system is said to have dramatically reduced the effectiveness of these bombs, which have been a major threat to Ukrainian cities and frontline positions. The developers claim Lima Quant is the only system in the world capable of suppressing the advanced guidance systems used by the KABs at long ranges.

Why it matters

Guided glide bombs have been one of Russia's most devastating weapons in the war, allowing them to strike targets deep inside Ukraine from a safe distance. Countering these bombs is crucial for protecting Ukrainian cities and forces. The development of the Lima Quant system represents a significant technological breakthrough that could shift the balance of power in this aspect of the conflict.

The details

The KAB series of guided glide bombs are the Russian equivalent of the U.S. JDAM precision-guided munitions. They can glide for dozens of miles and hit targets with high accuracy. To counter them, Ukraine previously used the original Lima jamming system, which caused the bombs' navigation to fail. However, Russia responded by developing more advanced Kometa guidance systems with more antenna elements that could resist jamming. The new Lima Quant system is claimed to have overcome even these improved Russian countermeasures, rendering the KABs ineffective at long ranges.

  • In 2024, Ukraine was able to counter the KABs with jammers, but new Russian receivers nullified the jamming.
  • In one recent month, Russia dropped 869 KABs on a 700 km stretch of the front, but with only minor injuries to 8 Ukrainian servicemen due to the Lima Quant system.

What they’re saying

“The effectiveness of KABs dropped to zero. On a roughly 700 km stretch of the front, the enemy dropped 869 KABs in one of the previous months. The consequences of these strikes were minor injuries to eight servicemen.”

— Spokesman, for the developers of the Lima-Quant system

“Today, Lima Quant is the only system in the world capable of suppressing these CRPAs at a distance of 50 km; KABs at distances of more than 100 km; and cruise and ballistic missiles at even greater distances.”

What’s next

Brigade commanders in Ukraine have sometimes imposed bans on using the Lima Quant system, arguing that it interferes with their own drones and aircraft. Resolving these coordination issues and ensuring widespread deployment of the Lima Quant system will be crucial next steps.

The takeaway

The development of the Lima Quant jamming system represents a significant technological breakthrough that could shift the balance of power in the war by neutralizing one of Russia's most devastating weapons. However, the ongoing electronic warfare arms race means any advantage is likely to be temporary, underscoring the need for continued innovation and coordination.
