Russia's EW Advantage

Russia has historically invested heavily in electronic warfare as a core capability:

• Russia's military doctrine places EW as a central component of combined-arms operations — suppressing enemy communications, navigation, and sensor systems is intended to precede every major ground operation
• Russia has deployed the world's largest and most diverse inventory of ground-based EW systems in Ukraine — providing substantial tactical advantage in communications disruption, drone jamming, and GPS denial
• EW density along the front is very high; Russian EW teams are typically deployed at battalion and brigade level, creating overlapping areas of effect
• By 2024, Russia was operating approximately 250–300 distinct EW systems of multiple types along the Ukrainian front — a technically overwhelming electronic environment for Ukraine to operate in
• Russia also benefits from significant SIGINT experience from its security services; signals intelligence informs targeting of Ukrainian command nodes and communications

Key Russian EW Systems

Ukraine's Initial EW Position

Ukraine began the war at a significant disadvantage in EW:

• Ukraine's pre-war EW inventory was primarily composed of Soviet-era systems (Kolchuga passive radar system, some Mandat and Malachit platforms) — capable in narrow tasks but far below Russian scale and modernity
• Ukraine's EW operator force was small and under-resourced relative to Russian counterparts
• Ukraine compensated initially by relying on Western commercial communications (Starlink, encrypted mobile applications) that Ukraine's own EW inventory could not disrupt and that Russia struggled to jam effectively, particularly when Starlink rapidly iterated its anti-jamming protocols
• Ukraine adapted quickly by establishing dedicated EW units, training operators on captured Russian systems and on Western-supplied equipment, and developing commercial-off-the-shelf solutions — an innovation pattern faster than the former Soviet military bureaucracy

Western EW Equipment and Support

Western nations have provided electronic warfare support carefully calibrated to avoid direct escalation:

• The US provided AN/MLQ-40 Prophet ground signals intelligence systems — tactical SIGINT platforms able to detect and locate RF emitters including Russian communications and radar
• UK EW support has included counter-drone EW systems; classified systems under export control cannot be publicly discussed
• Germany provided direction-finding and signals analysis equipment to help Ukraine map the Russian EW environment
• Sweden — particularly relevant given its advanced EW heritage through Saab and Ericsson — provided some EW advisory support
• The US Army's Electronic Warfare Planning and Management Tool (EWPMT) has been used in advisory capacity to help Ukraine plan EW operations and manage the spectrum
• NATO as a whole has been unusually forthcoming in sharing electronic intelligence on Russian radar and comms signatures, enabling Ukraine to detect and target Russian EW systems

The Drone EW Contest

The scale of drone usage in Ukraine made EW counter-drone capability suddenly the most contested dimension:

• Both sides operate thousands of FPV and reconnaissance drones daily; both sides have deployed EW systems specifically designed to jam drone control links and GPS navigation
• The primary countermeasure is frequency hopping — drone control systems that continuously change operating frequency, making static-frequency jamming less effective. Ukraine's drone operators have been extremely innovative in this space, often operating systems faster than Russian EW can adapt
• Russia responded with broadband noise jammers — systems that jam across wide frequency bands simultaneously — which degrade rather than eliminate drone operations over large areas
• Ukraine developed drones with autonomous flight modes that can complete attack runs without radio control once a waypoint sequence is programmed — removing the radio control link vulnerability entirely for one-way attack missions
• Russia deployed portable anti-drone EW systems (Repellent-1, Serp) at individual vehicle and squad level which, taken cumulatively, create dense point-defence jamming along front lines

Fibre-Optic Drone Innovation

The fibre-optic drone represents a partial tactical escape from the EW problem:

• A fibre-optic guided drone uses a physical wire (extremely thin fibre-optic cable) spooled behind it to transmit a real-time video feed and receive operator commands — physically impossible to jam with radio frequency EW systems
• Ukraine's drone developers pioneered commercial-scale production of fibre-optic FPV drones; they began appearing on the front in significant numbers in late 2023–2024
• Range limitations: fibre-optic cable limits drone range to 5–15km depending on cable spool size — adequate for front-line FPV strike missions but not deep-strike applications
• Russia has had to respond with physical anti-drone methods (nets, shotgun systems, dedicated observation and intercept) rather than pure EW solutions against fibre-optic drones
• Both sides are now developing fibre-optic drone capability; Russia began deploying its own versions in 2024
• The fibre-optic revolution illustrates Ukraine's broader strength in this conflict: rapid iteration on commercial technology by an entrepreneurial developer community, often outpacing the Russian procurement system

Current Balance Assessment

The EW balance as of early 2026:

• Russia still leads: In raw ground-based EW power, Russia maintains a substantial advantage in scale, system density, and operational depth. The front-line EW environment is extremely difficult for Ukrainian drones to operate in
• Ukraine leads in adaptation speed: Ukraine has consistently adapted faster — from Starlink anti-jamming to frequency hopping to fibre-optic drones. This innovation rate advantage is significant but cannot fully compensate for scale disparity
• GPS denial has been largely mitigated: Ukrainian forces rely much less on GPS for precision than they did early in the war. Inertial navigation, optical reference systems, and operator-in-the-loop control have reduced GPS dependency for many applications
• Western SIGINT intelligence fills some gaps: American and British intelligence on Russian EW system locations allows Ukraine to target and destroy Russian EW platforms — reducing their effective density over time
• Overall: contested near the front, Ukraine-favoured in the deep-drone domain: Close to the front line, Russian EW density is high enough to significantly degrade drone operations. In the 50–150km deep-strike domain where Ukraine uses longer-range kamikaze drones, EW effectiveness is lower and Ukraine has achieved significant results
