Cascade Systems

Cascade Systems is a Ukrainian defence-technology firm behind Lima, an electronic-warfare system built to counter satellite-guided Russian munitions. Rather than intercepting threats kinetically, Lima degrades and falsifies the GNSS signals that Shahed and Geran strike drones, glide bombs, and cruise and ballistic missiles rely on for navigation, pushing the incoming weapon off its intended target. The company is reported to be legally registered in the United States while its operations and development are rooted in Kyiv.

Operationally, Lima is run by the Kyiv-based “Night Watch” unit of Ukraine’s Territorial Defence Forces, which has built out a network of stations across the country since 2023. The pitch is cost and scale: company figures relayed by Ukrainian and international outlets describe a station priced around €58,000 and claim tens of thousands of Shahed jamming events and dozens of diverted cruise and ballistic missiles, with several hundred units delivered since mid-2024. Ukrainian Ground Forces electronic-warfare officers have publicly endorsed the capability while cautioning that a suppressed weapon “still falls somewhere” — the system diverts rather than destroys. An upgraded Lima Quant variant was introduced in early 2025.

Cascade sits among a wave of low-cost, electronic-warfare-driven Ukrainian startups reshaping air defence as stocks of expensive interceptor missiles run low. It works in the same broad counter-drone space as jamming specialists such as Kvertus and Piranha-Tech , though its focus on the navigation signals of long-range munitions sets it apart from the trench-level FPV jammers that dominate the field. The combat figures attached to Lima are company and operator claims relayed by media and have not been independently verified.
