For two years, electronic warfare was Russia's invisible advantage — the dense belt of jammers that made Ukrainian drones fall from the sky in their hundreds and taught the world that the FPV revolution had a counter. Through 2027, that advantage erodes from two directions at once: fiber-optic drones that cannot be jammed at all, and an EW industrial base that cannot replace its losses fast enough. Russia's next shortage will not be drones. It will be the things that stop them.
For two years, electronic warfare was Russia's invisible advantage — the dense belt of jammers that made Ukrainian drones fall from the sky in their hundreds and taught the world that the FPV revolution had a counter. Through 2027, that advantage erodes from two directions at once: fiber-optic drones that cannot be jammed at all, and an EW industrial base that cannot replace its losses fast enough. Russia's next shortage will not be drones. It will be the things that stop them.
The Belt Is Wearing Thin
Russia's EW architecture — Zhitel-class systems, Pole-21 GPS denial, thousands of tactical jammers layered along the contact line — was built on a simple wager: that drones depend on radio. The wager held through 2024. Then fiber-optic FPVs arrived, trailing 10–40 kilometers of unjammable glass behind them, and by late 2025 fiber variants accounted for a major share of FPV strikes on both sides. Every fiber drone that crosses the EW belt untouched is an argument that the belt's logic has expired.
The numbers are quiet but relentless. Russia fields thousands of EW systems; it also loses them — Ukrainian strike compilations have made jammers priority targets precisely because each one guards a sector of sky. Open-source tallies of visually confirmed EW losses run into the hundreds of high-value systems. Replacement depends on the same sanctioned electronics pipeline as everything else Russia builds — with the added complication that modern EW is semiconductor-hungry in exactly the categories under the tightest controls.
The Fiber Arithmetic
Fiber changes the cost equation in the defender's disfavor. A fiber FPV costs perhaps $500–1,000 more than its radio cousin — a spool, a payout mechanism, an optical transceiver. Against it, a tactical jammer costing hundreds of thousands of dollars contributes nothing. The defender's options collapse to the physical: nets, shotguns, interceptor drones, camouflage discipline. All work; none scale like a jammer did. Ukraine knows this firsthand — it is why Ukrainian forces weave nets over supply roads and why both armies now treat fiber spools as expendable infrastructure, scattered across the steppe like a second kind of barbed wire.
Russia's counter-move — its own fiber drones, produced in quantity — answers offense with offense but does nothing for defense. The jammer gap is asymmetric in a cruel way: fiber hurts the side that invested most in jamming, and Russia invested the most.
The Industrial Bottleneck
EW production compounds the problem. Russia's EW industry — concentrated in a handful of enterprises around specialized electronics conglomerates — competes for components with the drone, missile, and air-defense programs inside the same shrinking import pipeline. A modern jammer is a luxury good in this economy: precision RF components, power amplifiers, processing hardware, all contested, all sanctioned, all marked up through intermediaries. Where an FPV factory can run on commercial motors and hobby electronics, a Zhitel cannot run on hobby anything.
By 2027 the queue becomes visible: air defense takes priority for the component allocations, then strike drones, then — somewhere down the list — the EW systems whose loss rates Ukraine is actively engineering. Russian milblogger complaint cycles about EW coverage gaps, a reliable open-source barometer, have lengthened through 2026.
Ukraine's Own Version
The gap cuts both ways, and honesty requires saying so. Ukraine's EW layer — critical against the Shahed streams and Russian FPV density — faces the same component economics with the added burden of scale: Ukraine must jam across a front it defends everywhere. The difference is structural. Ukraine's EW effort is distributed, commercial-grade, and allied-financed — thousands of cheap jammers rather than hundreds of exquisite ones — a design philosophy that degrades gracefully where Russia's concentrated systems create single points of failure. When a Ukrainian jammer dies, a sector loses a component. When a Zhitel dies, a district loses its sky.
Every jammer is a bet that the enemy needs radio. Fiber-optic cable is the opponent that never placed the bet.
What to Watch
- Fiber share of strikes. As fiber FPVs cross half of recorded strikes, the EW belt's remaining value collapses to anti-reconnaissance and anti-bomber work — important, but not the shield it was. - EW loss compilations. The visually-confirmed attrition rate of high-value Russian EW systems is the shortage's leading indicator. - Russian EW export behavior. A country with surplus EW sells it; watch Russian export marketing of EW systems — silence there is data. - Interceptor substitution. Rising investment in kinetic counters — interceptor drones, automated cannon — on the Russian side signals the jammer-first doctrine being quietly retired.
The invisible advantage was always a production line wearing a cloak. Through 2027, the production line is the story — and Russia's is running short of exactly what the cloak is made of.
