German investigators now count three drones around the failed 4–5 August attack on a Ukrainian cargo plane at Leipzig airport, Tagesschau reported on 25 August. Officers found the third machine and a suspected military explosive in a field near the runways. Security circles assume Russian intelligence services helped plan the attempt, and Russia denies any role.

A third drone and about 50 grams of suspected hexogen

Investigators found the third drone on the early evening of 14 August in a field in Kabelsketal, security circles told NDR, WDR, and the newspaper Süddeutsche Zeitung (SZ). The area borders the airport's western edge in Saxony-Anhalt. Forensic technicians from Germany's Federal Criminal Police Office (BKA) arrived that day, and the next day they reportedly found a substance at the site. First assessments put it at about 50 grams of hexogen, a military explosive known internationally as RDX. The perpetrators may have had a far larger attack in mind than what has become public, according to Tagesschau. 

The target was a Ukrainian plane

The drone found on the tarmac was meant to hit a Ukrainian Antonov cargo aircraft that moves military goods, according to the investigation cited by the public broadcasters NDR and WDR and SZ. The bomb never went off, because its detonator was apparently defective. The plane had been apparently loaded with ammunition the previous day. Leipzig/Halle carries military freight for the German armed forces and NATO allies, and Ukraine's Antonov Airlines uses it as a base, Euronews reported the same day.

A bomb-laden drone hit a Ukrainian An-124 in Germany, then lay unnoticed for hours

The first drone turned up on the airport grounds at around 23:42 on 4 August. Shortly afterward, at about 00:03, a second drone reportedly collided with a cargo plane of the delivery company DHL. That aircraft had broken off its landing because the first find shut the airport, and it probably hit the drone at fence height at several hundred kilometers per hour. Neither that drone nor parts of it have turned up, NDR, WDR, and SZ reported. The German broadcasters placed the damage on the tail unit, while Bild gave a different account, putting the collision about six kilometers out with minor damage to the nose, Euronews said.

Camera footage analyzed after the attempt showed a quadcopter carrying Semtex plastic explosive fly into the wing of a parked An-124 Ruslan without detonating, and Washington assessed that the drone belonged to Russian intelligence. The same airport saw a parcel ignite in July 2024, before crews could load it onto a DHL cargo plane, in what security services treated as a suspected Moscow-linked arson plot.

State-protection officers at the BKA work under orders from Federal Prosecutor General Jens Rommel to establish how the attack was meant to run and who is responsible. Investigators are following several leads, among them recovered DNA. Germany ranks among Ukraine's biggest military backers, and its authorities suspect Russia of orchestrating many of the drone incidents as part of a campaign of sabotage, espionage, and disinformation, Euronews said.
