Ukraine’s war leadership sets new electronic warfare tasks as Russia’s jet-powered drones slip past nearly half of its air defenses

The headline number is the story: nearly half of Russia's jet-powered drones are getting through Ukraine's air defenses. That figure, paired with a presidential directive to set new electronic warfare tasks, tells us the air-defense problem has changed character. For two years the dominant narrative was interception rates climbing as Western systems arrived. Now the constraint is not radar coverage or operator skill but the physics and economics of engaging a fast, low-flying, relatively cheap airframe with interceptors designed for other threats. When a leadership publicly re-tasks its electronic warfare enterprise, it is effectively conceding that the kinetic layer alone cannot close the gap.

The mechanics matter. Jet-powered one-way attack drones occupy an awkward band. They fly faster and higher than the propeller-driven Shahed-type designs that shaped Ukraine's mobile fire-group tactics, but slower and lower than cruise missiles. That compresses engagement windows for gun crews and short-range missiles, and it stresses the cueing chain: detect, classify, hand off, engage. A jet airframe also changes the acoustic and infrared signature, which affects the passive sensors that many mobile teams rely on. Electronic warfare attacks a different link in that chain, the guidance and navigation path, and it does so at a cost per engagement that is orders of magnitude below a missile. The catch is that jamming is not a wall. It is a contest over antennas, waveforms, power, and geometry, and it degrades gracefully rather than decisively. Against a jet-powered platform, the jammer must also contend with higher speeds that shrink the time in which a spoofed or degraded signal can push the vehicle off target.

On the demand side, this is a clear signal to the counter-drone and electronic warfare supply base. Ukraine has already built an unusually deep bench of small and mid-sized EW producers, and the presidential framing suggests requirements will be pushed down to them rather than waiting on scarce, high-end Western systems. We would expect accelerated work on broadband jammers covering satellite navigation bands, on decoy and spoofing transmitters, and on passive detection networks that fuse acoustic, RF, and radar returns. The cost-exchange logic favors attritable, distributed systems over centralized nodes, because a single high-value jammer becomes a target. For primes, the implication is less about selling a flagship system and more about supplying components, power electronics, and software-defined radios at scale. For suppliers, the bottleneck is likely to be RF power components and the software to adapt waveforms quickly as Russia changes frequencies and guidance modes.
