Russia is testing a new drone with LTE communication. The Defense Intelligence of Ukraine (DIU) has published a 3D model, components, and parts of the new UAV that Russia is actively using on various frontline sectors.

Structurally, the drone has a fuselage similar to the Shahed-131 (Geran-1), but it is somewhat smaller. Nearly half of its components are manufactured in China, including communication modules, a mini-computer, a power regulator, and a quartz generator.
