The active use of RAM-2X kamikaze drones by the Ukrainian Defense Forces has already reached the point where russian sources openly complain about them, issue warnings, and call for effective countermeasures. Such reactions are a clear indicator not only of how effective the Ukrainian drone is, but also of how frequently it is being employed on the battlefield.
The latest catalyst was the widely circulated video of a RAM-2X strike on a heavy truck transporting a damaged tank. Different sources geolocated the attack site variously — near Debaltseve, Alchevsk, or, more likely, Kadiivka, about 40 km from the frontline.

Following that, several russian propagandist outlets sounded the alarm about the RAM-2X, essentially a counterpart to russia's own ZALA Lancet UAV. In doing so, they also indirectly highlighted which of its technologies they consider most problematic.
In particular, they noted that the RAM-2X uses the StreamCaster encrypted communication system from the U.S. company Silvus, featuring the mesh network technology. It creates a flexible communication web where each node acts as a repeater.
Even if individual nodes are jammed or disabled, the network automatically reconfigures itself, which makes disrupting such a system extremely difficult. At the same time, this is not a uniquely Ukrainian know-how — russia has also explored similar technologies. For example, reports from December 2024 confirmed efforts to integrate mesh systems into Shahed-136/131 killer drones and other UAVs.
Also, russian reports note that the RAM-2X operates in tandem with the Shark reconnaissance UAV, which uses a similar communication suite and likely acts as both a guide and a signal repeater. Shark itself has shown impressive resistance to electronic warfare, making the duo even more difficult to counter.
Another concern they share is that common russian drone detection systems do not pick up the RAM-2X, meaning its strikes often come as a surprise. The russian media have therefore urged electronic intelligence units to raise alerts whenever they detect StreamCaster signals — even deep in the rear — fearing that the RAM-2X may have a range of up to 150 km. Official specifications of the drone, however, have never been disclosed.
For a brief reminder, the RAM-2X was first publicly demonstrated in December 2024, operating in tandem with the Shark reconnaissance drone.
