Should civilian satellite communication networks be integrated into military targeting and surveillance operations?
Russia has developed a new electronic warfare system, the VKG, designed to disrupt Starlink satellite connectivity by targeting the 14- to 14.5-gigahertz frequency range. This man-portable system is intended to counter the use of Starlink-supported drone operations in Ukraine.
Why it matters
The development of a compact, portable jammer signals an escalation in the electronic warfare contest between ground-based denial systems and low-earth orbit satellite constellations. By specifically targeting the communication links used for drone guidance, the system aims to neutralize a critical tactical advantage currently held by Ukrainian forces.
The VKG unit weighs 120 kilograms and operates within the 14- to 14.5-gigahertz frequency band. It is capable of disrupting signals up to 16 kilometers away and can jam up to eight transmission bands simultaneously.
The players
Russian Military
The national armed forces of Russia, currently deploying electronic warfare assets to counter satellite-based communication systems in Ukraine.
The details
The VKG system functions by saturating satellite antennae with narrow-beam, high-frequency transmissions directed at the target satellite. By focusing these beams, the jammer forces a signal-to-noise ratio that disrupts communication links within a 20-square-kilometer area. While the system provides a four-kilometer protection radius for nearby electronics, it is specifically configured to isolate and block the high-bandwidth uplinks required for terminal operation.

The Tech Race
The introduction of the VKG jammer underscores a shift in satellite suppression, moving from crude broad-spectrum interference to targeted high-frequency disruption. This development represents a direct effort to nullify the communication edge currently provided by LEO satellite networks in active theater operations.
This development impacts military operations and defense logistics by introducing a portable countermeasure to high-speed satellite internet. It remains to be seen if current civilian Starlink hardware can be hardened against these specific 14-gigahertz narrow-beam threats.
The takeaway
The deployment of the VKG system signals that electronic warfare is rapidly pivoting to target low-earth orbit constellations with man-portable hardware. Observers should track the effectiveness of these jammers against future Starlink software-based frequency-hopping updates.
