How Russia’s New Jet-Powered Drones Are Forcing Ukraine to Rethink Its Air Defense

The drone war over Ukraine has entered a new and more dangerous phase. For much of the conflict, Ukraine found an effective, low-cost answer to Russia’s slow-moving Shahed-136/Geran-2 attack drones: cheap FPV interceptor drones that could chase them down and destroy them. That countermeasure worked so well that Ukraine’s interceptor fleet accounted for roughly 70% of all Shahed-type drones destroyed in early 2026, with 100,000 interceptors produced in 2025 alone .

Russia’s response has been to change the physics of the threat. Since early 2025, Moscow has been fielding jet-powered variants of the Geran family—principally the Geran-4 and Geran-5—specifically designed to outrun those interceptors . These are no longer the slow, moped-engined drones that became a grimly familiar sound over Ukrainian cities. They are faster, heavier, and much harder to stop, and they are arriving in the context of the largest aerial attacks of the war.

Jet-powered Gerans: faster, heavier, and built to outrun interceptors

The propeller-driven Geran-2 typically cruises at 150–180 km/h, giving mobile air-defense teams and interceptor drones a workable engagement window. The jet-powered Geran-4 pushes that speed to 350–500 km/h, and the Geran-5 can exceed it, with some reports citing top speeds of 500–600 km/h . At those velocities, the time available to detect, track, and intercept shrinks dramatically.

The Geran-5 also carries a significantly larger punch. Its 90 kg warhead is roughly triple the 30–40 kg payload of the Geran-2, and its 1,000 km range means it can reach targets deep inside Ukrainian territory . The drone can be air-launched from aircraft like the Su-25, extending its reach further still . As a hybrid between a loitering munition and a stripped-down cruise missile, it blurs doctrinal categories and complicates defense planning .

Ukraine’s military intelligence directorate (GUR) confirmed in May 2026 that Russia began using the newer Geran-4 “as a countermeasure” to Kyiv’s increasingly effective interceptor drones . For now, production of these jet-powered variants remains limited. The GUR has stated that the Geran-4 and Geran-5 are not yet being produced at scale, though work is underway to expand manufacturing capacity .

From swarms to combined strikes: Russia’s tactical evolution

The jet-powered drones are not operating in isolation. Throughout 2026, Russia has shifted from the mass drone swarms that defined 2025 toward sophisticated combined strikes that layer jet-powered drones, ballistic and cruise missiles, and cheap decoy UAVs into a single, multi-vector attack . The goal is to saturate Ukraine’s multi-layered air defense, compress the decision cycle for operators, and force difficult trade-offs between engaging high-speed threats and conserving expensive interceptor missiles.

These tactics have been paired with an enormous increase in volume. Russia launched approximately 55,000 suicide drones in 2025—a fivefold increase over the previous year . In the first three months of 2026, Moscow deployed more drones than in all of 2023 . On March 24, 2026, Russia launched 948 drones in a single 24-hour period, the largest single-day drone attack of the war to date . The following month set a new monthly record: 6,663 drones and 141 missiles launched at Ukraine in April 2026 alone, nearly 88% of which were drones .

Ukraine’s drone-for-drone defense and industrial scale

Ukraine has not been passive in this escalation. The Armed Forces recorded nearly 820,000 drone strikes against Russian targets in 2025, with President Zelensky noting that “over 80% of enemy targets are destroyed by drones,” the vast majority of them manufactured in Ukraine . Through the “Army of Drones” program, Ukraine has become a drone production hub, churning out tens of thousands of FPVs each month and deploying millions of maritime and aerial drones annually for reconnaissance, targeting, and precision strikes .

Interceptor drones remain the centerpiece of Ukraine’s cost-effective defense against slower Shahed-type UAVs, and their success has generated international demand. Ukrainian interceptor technology is now being sought after in the Middle East to counter Iranian Shahed attacks . But against the jet-powered Gerans, current interceptors lack the speed to reliably engage. Closing that gap will require faster interceptor designs, more advanced radar cueing, or a return to greater reliance on traditional ground-based air defense systems—options that are all more expensive and harder to scale.

How record drone numbers are reshaping the battlefield

The sheer density of drones has transformed the front line. Drone-inflicted casualties have risen from less than 10% of total losses in 2022 to as much as 80% by 2025 . Both sides now lose the majority of their personnel and equipment not to artillery barrages or infantry assaults but to small, cheap, remotely piloted aircraft .

Several trends have converged to produce this outcome:

Fiber-optic FPVs have changed the electronic warfare calculus. Tethered by spooled cable, these drones are immune to radio jamming. Russian fiber-optic FPVs proved decisive in the Kursk sector, where their resistance to electronic warfare helped make Ukraine’s position unsustainable over seven months of fighting, ultimately contributing to Kyiv’s withdrawal in March 2025 . Both sides now field fiber-optic systems in large numbers.

The battlefield has become transparent. The density of surveillance drones means that troop concentrations, armor movements, and logistics convoys are detected within minutes anywhere along the 745-mile front . The era of massed, surprise maneuvers is effectively over without extensive electronic warfare cover or the willingness to absorb catastrophic losses.

Cost asymmetry is driving attrition on both sides. FPV drones costing $300–$500 are destroying million-dollar air defense radars, tanks, and artillery pieces at rates that strain industrial replacement. Russia uses mass drone salvos against civilian infrastructure in part to deplete Ukraine’s stock of expensive surface-to-air missiles, while Ukraine uses cheap drone-on-drone interception as its most sustainable defense.

The introduction of jet-powered attack drones does not yet represent a decisive shift in the air war—production numbers remain low, and Ukraine’s layered air defense network has proven adaptable. But the trajectory is clear. As Russia moves from slow, mass-produced propeller drones to faster, more lethal systems that demand more expensive countermeasures, the economic and industrial dimension of the drone race will become as important as the tactical one.
