Ukraine is expanding its use of high-speed interceptor drones as Russia deploys more jet-powered attack UAVs. Ukrainian drone maker Wild Hornets said its new Sting S interceptor was recently used by a tactical air-defense unit to shoot down a Russian Geran-5, among the first combat results disclosed since the system entered field testing.
A Wild Hornets spokesperson said Ukrainian forces had downed several Geran-5 drones over the past few days, as well as about 12 slower jet-powered Geran-4 aircraft. The company plans to begin mass production of the Sting S after testing ends, but has not yet released figures for its production capacity, operating speed or unit cost.
Sting S operators control interceptions remotely
The Sting S is an upgraded version of Wild Hornets' existing bullet-shaped Sting drone. The company said operators using its Hornet Vision Ctrl system carried out most of the interceptions recorded during field testing. The system allows Sting pilots to operate from a secure position hundreds of miles from the launch site, reducing exposure near the front line and air-defense positions.
Wild Hornets is not the only Ukrainian group developing high-speed interceptors. On September 20, Ukrainian President Volodymyr Zelenskyy released footage of another interceptor drone and said it had been developed by an unnamed manufacturer and was already in service with Ukraine's Security Service, or SBU.
The aircraft features a delta-wing design and a jet engine. Its appearance bears some similarities to earlier Geran models, but its airframe is clearly different from the Sting family. The SBU said the system had also destroyed a Geran-5.
Geran-5 can approach 375 miles per hour
Ukrainian intelligence services describe the Geran-5 as one of the more advanced and fastest models in Russia's Geran family. It can reportedly travel at close to 375 miles per hour and carry a warhead weighing about 200 pounds. Earlier in the war, Russia relied more heavily on the piston-engine Geran-2, a Russian-produced version of Iran's Shahed-136 used mainly in attacks on Ukrainian cities.
After Ukraine developed interception methods aimed at propeller-driven drones, Russia began developing Geran variants powered by small turbojet engines. The three jet-powered models identified so far have cruising speeds above 200 miles per hour. The Geran-5 is also closer in size and shape to a cruise missile than to the slower attack drones used earlier in the conflict.
Russia has expanded air-base infrastructure to support the launch of jet-powered drones. Ukrainian intelligence warned in May that Moscow planned to increase the frequency with which these aircraft were used in attacks.
Jet-drone launches rise sharply
Ukraine's Air Force said Russia launched about 2,800 jet-powered drones in August, compared with 350 in June. As the scale of the attacks has grown, interception has become more difficult. Ukraine's interception rate against conventional propeller-driven drones is at least 90%, while the rate against jet-powered models has fallen to about 60%.
Ukraine currently uses fighter aircraft and surface-to-air missiles against jet-powered drones, while also accelerating work on interceptors that are faster and more suitable for large-scale deployment. Earlier interceptor drones typically cost several thousand dollars each, well below the value of the targets they were designed to destroy. The eventual price and battlefield performance of the Sting S remain undisclosed.
The reported Geran-5 interceptions indicate that Ukraine is developing several approaches to counter high-speed drones. The systems remain in testing or early deployment, however, and there is not yet enough data to assess their production rates, real-world interception performance or ability to cope with a sustained increase in Russian jet-drone launches.
