Russia has been using a new type of fast, jet-powered drones against Ukraine regularly throughout August, according to an analysis by BBC Verify of Ukrainian Air Force data. This is the first time that daily attacks using Moscow’s upgraded Geran drones have been recorded in the data. The increased use of these jet-propelled drones, along with other types, led President Volodymyr Zelensky to describe the situation as an unfolding "horror" over the skies of Kyiv. The number of jet-powered drone attacks rose sharply, from 350 in June to 1,600 in July and 2,800 in August. In five of the nightly attacks in August, these faster drones outnumbered the older, slower models. Dr. Marina Miron, a military technology expert from King's College London, explained that the shift to jet-powered drones is due to their speed, which makes them harder to intercept. These upgraded drones can travel at over 300 mph, much faster than older models and well beyond the speed of Kyiv’s interceptors. Some of the turbojet engines used in the drones are believed to be sourced from China, according to Ukrainian military intelligence. These drones were used in attacks on 1 September that killed at least 12 people and injured 20 others. Six of the casualties were railway workers after a depot in Kyiv was hit. Earlier this year, Ukraine had shown success in intercepting Russian drones, with Zelensky stating that 94% of long-range drones were being stopped. However, the speed of the newer jet-powered models has led to a new arms race between Kyiv and Moscow. On 10 August, Ukraine’s deputy head of military intelligence, Maj Gen Vadym Skibitskyi, said his forces needed new interceptor missiles "capable of matching [jet-drones'] speed." Four Ukrainian companies have started testing missiles designed to shoot down the new Geran models, and the country’s new defense minister, Yevhenii Khmara, has ordered them to produce "thousands of units" as quickly as possible. Satellite images suggest that Russia is redesigning key facilities to support its jet-powered drone operations. A new base at Tsymbulova in the Oryol region, about 109 miles from the Ukrainian border, now appears to be a major center for these attacks. The facility, which was not previously noted in Air Force reports, has become a key launch site for Russian drones since becoming operational. Analysts note that while jet-powered drones are becoming more sophisticated, they are still not as advanced as cruise missiles, with shorter ranges, smaller warheads, and greater susceptibility to jamming systems. Meanwhile, Russia is using increasingly complex attacks involving hundreds of drones and missiles about once a week, combining a variety of weapons to challenge Ukraine's air defenses.
