A hobby computer, a cheap airframe, and a Russian jet drone: how Zirka’s upgrade scored its kill

An upgraded Ukrainian Zirka interceptor caught and destroyed a Russian jet-powered Geran-5 drone, its developer, the ZRK tech project, said. A crew from Ukraine’s drone forces flew the self-guiding drone, ZRK added. At its summer debut, the cheap interceptor looked too slow for Russia’s jet models.
Russia sends waves of attack drones at Ukrainian cities almost every night. It has spent the year moving more of them onto jet engines. The faster models slip past many of the cheap interceptors Ukraine built for propeller Shaheds. That leaves gaps Ukraine often plugs with expensive missiles, and Washington is holding back the ones Ukraine needs most.
Caught at 3,500 meters
ZRK said the upgraded Zirka chased down the Geran-5 at about 400 km/h, at an altitude of 3,500 meters. The developer published the interception video on 31 October.
The crew “Retro” of the Darknode battalion flew the mission, ZRK said. The battalion belongs to the 412th Nemesis brigade of Ukraine’s Unmanned Systems Forces. ZRK has not disclosed the upgraded drone’s specifications.
From too slow to catching a jet
When Zirka debuted in late June, its makers listed a top speed above 340 km/h. They also gave a 6 km ceiling and a 30 km radius. At up to $2,000 a unit, they called it the cheapest interceptor in its class with automatic guidance. That speed fell short of the bursts Russia’s jet-powered Shahed variants can reach.

Zirka still found a way against jets. In late July, it downed a jet-powered Geran-4, its maker said in a press release, Militarnyi reported. Instead of chasing the faster drone from behind, Zirka met it head-on or from the side, Ukrainian tech outlet ITC explained.
Oleksii Babenko, director of investor Vyriy Industries, later said Zirka could down jet Shaheds on its own. He also said it once hit a target about 3,000 km from its operator, controlled via Starlink.
A hobby computer does the aiming
Zirka carries a Raspberry Pi 5, a credit-card-sized single-board computer, Militarnyi said. It runs a machine-vision model trained to pick out the features of Shahed-type drones. The system detects a target up to 1 km away. Once the operator confirms it, the system tracks it and steers the interceptor in.

The pilot only has to adjust the closing speed, Militarnyi added. Machine vision makes Zirka up to 60% more effective against maneuvering targets than manual piloting, NOCTIS claims, according to ITC. ZRK’s new video shows the software flagging the Geran-5, then switching to automatic terminal guidance, so the upgraded version likely keeps the same system.
Ukraine’s answer to Russia’s jet Shaheds: a jet drone named Bars, built to strike Russia and now turned around to hunt them
That is the capability Ukraine’s presidential adviser on defense technology Serhii Beskrestnov has pressed for. Speed alone will not catch jet drones, he argued. Interceptors need machine vision to lock on and guide themselves in.
The battalion behind the brief
Ukrainian company NOCTIS built Zirka to a technical brief drawn up with the Darknode battalion, ITC said. The battalion, one of Ukraine’s top anti-Shahed units, has downed more than 1,500 Russian drones, according to ITC. Vyriy Industries holds a 30% stake in NOCTIS, Babenko said.
Cheap answers to cheap drones
Ukraine’s government wants exactly this kind of trade. “We need asymmetric effect,” Defense Minister Yevhenii Khmara said, as Kyiv funds its own missiles and radars. The goal is to stop spending costly interceptors on Russia’s cheap drones.
Until cheap tools catch up, Ukraine improvises with what it has. One regiment has paired a Soviet Kub launcher with a Buk radar to hunt jet drones. It has also rewired launchers to fire American RIM-7 missiles.
Russia keeps speeding up
Ukraine shoots down 50–60% of Russia’s jet-powered Shaheds, against 85–92% of propeller ones, Ukrainian President Volodymyr Zelenskyy said in October. Russia builds about 3,000 jet drones a month, Ukraine’s military intelligence (HUR) estimated.
HUR puts the Geran-5’s cruise speed at 450–600 km/h, and Beskrestnov said it has hit 1,000 km/h in maneuvers. He added that Ukraine’s jet interceptors still struggle with guidance, automatic target lock, and mass production.
Zirka is not alone. The 1020th anti-aircraft regiment caught a Geran-5 at 425 km/h in September. Wild Hornets says its new STING-family interceptor has destroyed about ten Geran-4s.
