Moscow displayed the Volna Kupol Garant system on 2 August 2026, announcing it as a dedicated tool to disrupt Starlink terminals used by Ukraine and allied forces. The unveiling took place at a national defence exhibition, with senior officials describing the system as a „strategic countermeasure” against foreign satellite communications.
The new system targets the ground antennas that receive data from Starlink satellites. According to Russian defence representatives, it floods those antennas with spurious signals, forcing the satellites’ receivers to overload and temporarily shut down. By impairing the link between user terminals and the orbital constellation, the system can render the broadband service unusable for short periods. Officials said the capability was developed in response to the growing reliance on Starlink for military coordination and civilian resilience in conflict zones.
Volna Kupol Garant allegedly injects high‑power radio bursts into the frequency bands allocated to Starlink user terminals. The bursts are synchronized with the satellites’ transmission schedule, creating interference that exceeds the terminals’ processing limits. Russian engineers claim the approach can „blind” a terminal within seconds, after which the device must reboot to restore connectivity. The Ministry of Defence noted that the technique does not require direct line‑of‑sight to the satellite, allowing deployment from mobile platforms deep inside contested territory.
Analysts caution that the system’s effectiveness will depend on several variables, including the density of Starlink ground stations and the robustness of the network’s adaptive protocols. While a temporary loss of service could hinder real‑time command and control, Starlink’s built‑in redundancy and the possibility of alternative frequencies may mitigate long‑term disruption. Ukrainian officials have not confirmed any operational impact, but they have warned that any interference could force a shift toward less secure communication channels.
The debut of Volna Kupol Garant signals a new phase in electronic warfare, where satellite internet is a contested battlefield. If the system functions as described, it could pressure satellite providers to develop stronger anti‑jamming measures. Observers expect a rapid escalation in counter‑measure research, with both sides seeking to protect or undermine critical data flows. The coming months will reveal whether the technology reshapes the information landscape of the ongoing conflict.
What is Volna Kupol Garant? It is a Russian electronic‑warfare platform designed to overload the receiving antennas of Starlink terminals, temporarily disabling their internet connection.
How does the system interfere with Starlink? The system transmits high‑power radio bursts that flood the frequency band used by Starlink terminals, causing the satellite receivers to become overloaded and shut down.
Could this affect civilian users of Starlink? Yes, any terminal within the interference zone—military or civilian—could lose connectivity while the jamming signal is active.
