Merops is documented in Ukrainian service during the 2014 Russia-Ukraine War as a counter-drone system used against Russian-operated one-way attack drones. Defense News reported that Ukrainian forces first used the system in June 2024 against Russian-operated systems, including Shaheds.
NATO later described the American-made system as having already taken down more than 1,000 Russian drones in Ukraine, and Business Insider reported the same scale of Shahed-style drone kills while quoting U.S. Army Brig. Gen. Curtis King that Merops had been highly effective and lethal against one-way attack drones in Ukraine.
Reuters Connect separately documented a Ukrainian service member installing a warhead into an AS3 interceptor UAV, part of the American-made Merops system, during training in an undisclosed Ukrainian location on 10 April 2026 amid Russia's attack on Ukraine.

Timeline
The public record places Merops in Ukraine by mid-2024, with later NATO and U.S. reporting using the Ukrainian experience as the basis for eastern-flank fielding in Poland and Romania. Defense News identifies June 2024 as the first Ukrainian use date, while NATO's November 2025 demonstration page and Business Insider's reporting connect the system's NATO adoption to combat use against Russian Shahed/Geran-type drones.
By April 2026, Reuters had photographed Ukrainian training with the AS3 interceptor, and Defense News reported a Ukrainian unit's video that experts believed could show Merops targeting a Shahed/Geran-type drone. That later video remains attributed and partly unverified in public reporting because the Ukrainian unit did not specify which interceptor it used.

Narrative
Merops fills a short-range air-defense role against one-way attack UAVs rather than a conventional missile-defense role. Public sources describe a mobile system built around launch equipment, a ground control station, and the Surveyor or AS3 interceptor drone. The interceptor can be launched from a pickup-mounted or ground-station launcher, can use thermal, radio-frequency, or radar inputs, and is reported to be resistant to electronic warfare.
The system's documented Ukrainian target set is Russia's Shahed/Geran-type strike-drone campaign. NATO and Business Insider framed Merops as a way to defeat Shahed-style drones at much lower cost than conventional air-defense missiles, while AP reporting on NATO eastern-flank deployment described Merops as a drone-against-drone system for detecting, closing with, and defeating hostile UAVs.
Public sources support Ukrainian fielding, training, and high-volume use against Russian drones, but they do not provide a fully audited incident log with every Merops intercept by date, location, unit, and target. The strongest exact claims for this record are Ukrainian use beginning in June 2024, more than 1,000 reported Russian or Shahed-style drone intercepts in Ukraine, and April 2026 visual documentation of Ukrainian training with a Merops AS3 interceptor.
