Ukrainian defense technology company Cascade Systems, founded in 2022, said its Lima electronic warfare (EW) system has evolved from countering drones and glide bombs to disrupting some of Russia’s most advanced precision-guided weapons, including Kh-47M2 Kinzhal aeroballistics missiles. The system’s name comes from one of Night Watch’s reported electronic warfare techniques of spoofing enemy navigation systems and making Russian drones and missiles believe they are located over Lima, Peru, causing them to veer off course.

According to the company and Ukraine’s Night Watch electronic warfare unit, the system has neutralized 58 Kinzhal missiles, diverted 33 cruise missiles, and disrupted more than 20,000 Russian UAVs, while achieving a claimed success rate of over 98% against glide bombs within its coverage area.

Developed in 2022, Lima uses electronic warfare techniques—including jamming, spoofing, and manipulating satellite navigation systems—to redirect drones and missiles away from their intended targets. A newer version, Lima Quant, is designed to counter advanced multi-channel satellite navigation antennas used on modern Russian precision weapons. Ukrainian officials said the system has become an important part of the country’s layered air defense network, reducing reliance on expensive interceptor missiles such as the Patriot air defense system by electronically defeating incoming threats before kinetic interceptors are required.

According to BFBS Forces News, Ukrainian developers also said the technology was tested alongside the US military in the Middle East and has attracted interest from NATO partners. Cascade Systems argues that expanding Lima’s deployment could provide a cost-effective, non-kinetic layer of protection for cities and critical infrastructure while strengthening Ukraine’s overall air defense capabilities.
