Report: Russia fields Geran-4 with Susannin optical-correlation navigation

Ukraine's GUR reports a new Geran-4 jet UAV variant with a localized Russian engine, an added optical-electronic correlation navigation system (“Susanin”) to match terrain imagery and correct its route under GNSS denial, and a new cumulative-cutting warhead intended for bridges and power pylons. If accurate, this indicates improved resilience to jamming/spoofing and more specialized infrastructure-targeting payloads.
