Russian Geran-4 loitering munition features domestic engine and EO nav

Bottom line

Russian sources report the new Geran-4 loitering munition replaces Chinese Telefly engines with domestic Alabuga units and uses Sushanin EO correlation navigation, enabling strikes on bridges and lines.

Why it matters

The integration of domestic engines and EO correlation navigation reduces reliance on Chinese components and may improve resilience against GPS jamming, while the cumulative-fragmentary warhead design specifically threatens critical Ukrainian infrastructure and bridge networks.

Ukrainian GUR and Russian milbloggers report on the operational deployment of the Geran-4 loitering munition. The system features a localized Russian engine manufactured by Alabuga, replacing the previously used Chinese Telefly powerplant. It utilizes Sushanin electro-optical correlation navigation for guidance and carries a cumulative-fragmentary warhead optimized for infrastructure targets such as bridges and communication lines. Footage from Brigada VARYAG confirms Geran-4 strikes on the roadway and cable supports of Kyiv’s North Bridge on October 3–4, while Kalashnikov has publicly presented the Kub-10ME variant, claiming a 100km range and EO guidance for moving targets. This indicates a shift toward domesticated supply chains and specialized infrastructure targeting capabilities.
