Ukraine’s drone secrets lifted by EU firms promising fake battlefield tests

European firms stole drone secrets from a top Ukrainian manufacturer while falsely claiming their own UAVs were tested in combat, according to Skyeton CEO Roman Knyazhenko. He did not name the specific European companies allegedly involved. Skyeton’s flagship Raybird drone has flown over 350,000 combat hours, The Telegraph says. 

European drone makers accused of copying, then vanishing

In an interview with The Telegraph, Knyazhenko said some European manufacturers approached Skyeton under the pretense of cooperation. However, then they used the meetings to extract technical details and even plagiarized phrases from company materials.

“Sometimes I open presentations of other aircraft from Europe, and I see literally my own words, without any change,” he told the outlet.

He said firms conducted only a few drone flights far from the front line — such as in Lviv in western Ukraine — and still claimed their systems were “combat tested.” These misleading claims allowed them to secure government contracts worth billions, diverting funds from proven Ukrainian systems.

“They’re investing in technology that’s actually fake. In the end, you will have nothing,” Knyazhenko said, warning that the deception not only wastes money but also harms Ukraine’s war effort.

Skyeton says Raybird drones built under battlefield pressure

Skyeton, formerly focused on ultralight aircraft, now works directly with the Ukrainian army. CEO Roman Knyazhenko said roughly half the drone’s components have been replaced in recent years to enhance radar evasion and endurance. The system can reportedly fly 2,500 kilometers and stay airborne for up to 28 hours with various payloads. He added that pressure on engineers is extreme, with repairs often needed overnight to avoid leaving brigades without support.

“In peacetime, you would say a couple of weeks or a month. But right now, you have one night,” Knyazhenko said. “Because if you do not do it in one night, tomorrow the enemy will try and approach us and we will not have aircraft in the air, so we will have casualties.”

Poor foreign parts and legal limbo slow Ukrainian production

Skyeton says it had to start building more parts itself after receiving faulty imports. Knyazhenko cited one shipment of gimbal cameras where half didn’t work. Test logs showed they failed before leaving the factory, he said. The supplier denied responsibility. Legal action, Knyazhenko added, would take years — while frontline units went without equipment.

“Every day of delay will cost us millions,” Knyazhenko said, noting Skyeton’s strict government contracts and the constant demand from Ukrainian brigades.

Rapid evolution defines Ukraine’s drone edge

Skyeton says it constantly refines its drones for real combat conditions. Engineers, it claims, adjusted launch systems and designed UAVs that can take off from puddles within minutes. Knyazhenko said key technologies may become obsolete in two weeks.

“Three years here feels like 20 years in peace time,” he said.

He warned that visiting a Ukrainian factory doesn’t mean firms can replicate the work. “It’s the same story as building a BMW from scratch. It takes years,” he said.

In Foreign Affairs, former Biden officials Jon Finer and David Shimer said most countries — including the US — now lag behind Ukraine in drone warfare. Knyazhenko added that instead of rebuilding systems like the Raybird, Western countries should simply fund Ukrainian production abroad.
