Russia's latest jet-propelled Geran-4 and Geran-5 one-way attack drones fly at 500 km/h or more, nearly three times as fast as an older, propeller-driven Geran-2.

That's too fast for many of Ukraine's air defenses. In particular, the inexpensive interceptor drones that Ukrainian forces deploy by the thousand.

Russia launched more than 2,700 jet Gerans at Ukraine in September, and Ukraine is shooting down only about 55% of them, according to Ukrainian President Volodymyr Zelenskyy. The speed disparity is a big part of the problem.

Ukrainian forces are scrambling for new defenses against the speedy Gerans. Among the best is actually a Ukrainian take on the Geran-4 and Geran-5: a fast, jet-propelled one-way attack drone that the Ukrainians have modified for air-to-air use.

Against jet drones, the air-to-air Bars have a hit rate of around 30%, Zelensky said during a joint press conference with German Chancellor Friedrich Merz in Kyiv on 4 October. "The Bars have shown positive results," Zelensky said. "They currently have the highest percentage. Others are also catching up."

In July, Ukraine and Germany agreed to jointly produce Bars, with Germany financing the first phase. Ukraine has reportedly been launching Bars at targets on the ground since at least the summer of 2025. But it was only recently that clear photos and videos of the drones have circulated.

Over the weekend, Ukraine’s 1021st Anti-Aircraft Missile and Artillery Brigade released footage of one jet drone hunting another. Observers identified the interceptor as a Bars and its target as a Geran-5. After launching from an elevated ramp with help from a rocket booster, the drone's operator—seeing what the drone saw through a front-facing infrared camera—steered the drone toward the Russian drone, possibly destroying it.

Exactly how the operator controlled the Bars—whether by satellite or mesh radio or some other command and control system—is unclear. Equally unclear: what kind of warhead a Bars would employ in the air-to-air role. Many smaller interceptor drones lack warheads. Instead, they simply slam directly into their targets, wrecking them in the collision.

Mystery drone

Bars isn't small. It likely packs an explosive warhead. Potentially one that the operator can remotely trigger when the interceptor passes near its target.

Bars is adaptable. Its maker has reworked it from a 22-kg warhead and a 700-km range to a 60-kg warhead and a stated range of more than 1,000 km, and a heavier variant can carry a 105-kg warhead.

In the air-to-air interceptor role, long range is terribly important but speed is everything. There's an obvious way for the Ukrainians to boost the Bars' speed from its reported 700 km/h top speed to potentially even faster. They could shrink the drone's warhead and its fuel load, making it lighter in order to make it faster.

That may explain how a Bars can chase down a Geran-5 even as the Russians, by one Ukrainian analyst's estimate, try to push the Geran-5 toward 700 km/h or more.

Cost is important, too. Russia churns out Gerans for an estimated $100,000 or so per drone. The cheaper the drone, the more copies the Russians can fling at Ukrainian cities. If it takes three or more interceptor drones to take down each of those 2,700 jet Gerans, Ukraine may need to deploy 8,000 to 10,000 interceptors a month.

Ukraine already builds more than 2,000 Bars a month, its maker says, but mostly in strike versions. How many go to air defense, and how much each costs, isn't public.

The supply of small jet engines could be a constraint. “Engines are a key element; we really import them in large quantities,” Zelensky said in an interview with Financial Times. "There are also domestically produced engines, but there are not enough of them.” A Ukrainian-made engine for Bars passed final tests in September.

US defense-tech company CHAOS Industries introduced its Vespid interceptor family in Washington on 12 October, as the Association of the US Army (AUSA) annual meeting opened there, the company announced. CHAOS pitches the drones as low-cost defense against small and mid-size drones and one-way attack munitions. The company expects initial production capacity of 12,000 interceptors a year, expandable to 50,000 as demand grows.

The pitch lands as Russia moves its strike drones to jet power. Russia has stopped building the Geran-3, an earlier jet model, and makes about 3,000 faster Geran-4s and Geran-5s a month, Ukraine’s military intelligence (HUR) told Militarnyi in August. In mid-September, Ukrainian President Volodymyr Zelenskyy said two Ukrainian companies had passed combat tests with interceptors against such drones, while 67 were still working on them. Ukrainian defense outlet Defense Express measured the new US drones against exactly that threat.

One to carry, one to launch in batches

The Mk 1 made its first public appearance on 12 October aboard a Forterra MESA autonomous ground vehicle, Army Recognition reported. It fires from tubes on launchers such as the 10-round ISS Aerospace HAL10. It takes midcourse guidance from CHAOS radars or external command systems, then an AI-assisted infrared seeker handles the final approach, the company says. An electric ducted fan rather than a jet engine drives it, which CHAOS says cuts cost and logistics compared with turbojet interceptors.

The smaller Mk 0 is man-portable and needs no operator input once fired, its product page says. Both are rated to reach a target in under 100 seconds, with a listed range of 10+ km. Defense Express called that range a serious weakness that more launchers around a city could offset.

CHAOS lists cruise speeds of 100 m/s (360 km/h) for the Mk 0 and 150 m/s (540 km/h) for the Mk 1. Defense Express said those speeds may be enough to intercept the Geran-4 and Geran-5, which it puts at 340 km/h and 450–600 km/h.

Ukrainian makers say their interceptors already down jet Gerans

Wild Hornets’ Sting interceptors downed several of the slower jet-powered Geran-3s in November 2025. An unnamed Wild Hornets representative told NV, in an interview published on 22 September, that the company’s new interceptor had destroyed about ten Geran-4s and several Geran-5s in limited use. The company plans mass production within a month of finishing combat tests.

On 12 October, former Defense Minister Mykhailo Fedorov said he and Pavlo Yelizarov, commander of Lasar’s Group, had created a new interceptor with troops and engineers. He said it downed two Geran-5s headed for Kyiv.

Crews from Lasar’s Group, which Fedorov has called a National Guard special unit, flew those combat tests, he said. Separately, Fedorov reported in August that a Ukrainian jet interceptor with a top speed above 600 km/h had entered combat testing.

Russia has nearly finished the first section of a new launch site for jet-powered Geran-5 attack drones near the town of Millerovo in Rostov Oblast, anonymous Ukrainian OSINT channel Absolutely Reliable Source reported on 13 October. The channel’s bio says it covers Ukraine’s deep strikes and that its author belongs to a larger, unnamed structure. It says Russia rushed the build to scale up attacks after its September strikes on Kyiv.

The site is meant for the kind of drone Ukraine stops far less often than the older Shaheds. Ukraine downs 55% of jet-powered Shaheds, the class that includes the Geran-5, and more than 90% of the older propeller-driven ones, President Volodymyr Zelenskyy said on 26 September. Russian industry makes about 3,000 Geran-4 and Geran-5 drones a month, Ukraine’s military intelligence (HUR) told Militarnyi in August. A new launch site is how Russia plans to fire more of them, the channel argues.

Built in weeks, by the channel’s count

The channel’s images from 1 September show no construction at the site. The latest ones show eight prepared positions for launchers and 32 places for preparing drones for launch, the channel wrote. Imagery from the day before its post shows drones being unloaded in one zone, it said.

The channel’s headline says the work took a month. Ukrainian outlet Militarnyi, comparing the channel’s own images from 1 September and 12 October, put it at about six weeks. Both readings rest on the same images, which have not been independently verified.

Built like Tsymbulova

The construction style is very similar to Tsymbulova, Russia’s jet-drone base in Oryol Oblast, the channel wrote. That base has separate positions for storing, preparing, and launching jet drones, Militarnyi said. By late May, less than a month into an expansion of Tsymbulova, Russia was already building 10 more launchers there.

Ukrainian drones have hit Tsymbulova repeatedly, though most of the damage imagery comes from Absolutely Reliable Source. Militarnyi reported strikes on the base’s bunkers and hangars in September. Ukraine’s Defense Forces struck it again overnight on 1 October, damaging two ground shelters and drone preparation areas, Absolutely Reliable Source said. On 10 October, OSINT channel Exilenova+ reported another drone strike there, saying several bunkers, one jet-drone launcher, and a drone storage area were hit.
