Direct proof of use
Open sources directly tie the Primoco One 150 family to Ukrainian service through foreign military aid after Russia's 2022 full-scale invasion. Defense Express reported on 26 November 2022 that Luxembourg delivered six Czech-made Primoco One 150 UAVs to Ukraine as military aid for the Ukrainian armed forces.
Germany's official military-support list separately records 18 delivered Primoco ONE reconnaissance drones. Defence Industry Europe reported a November 2023 German tranche and described the aircraft as Primoco unmanned aerial vehicles delivered to the Armed Forces of Ukraine for tactical intelligence, surveillance, and reconnaissance.

Delivery timeline
The first public delivery milestone in the sources used here is Luxembourg's six-aircraft transfer reported in late November 2022. Defense Express attributed the information to Army Recognition and Luxembourg Ministry of Defense sourcing, and described the aircraft as surveillance and reconnaissance UAVs.
Germany's public aid trail adds a later delivery line. Defence Industry Europe reported that the German government announced Primoco ONE deliveries in early November 2023, while the current German federal aid list records 18 Primoco ONE reconnaissance drones delivered to Ukraine.

Operational role
The documented Ukraine-war role is reconnaissance and surveillance. Defense Express described the One 150 as a medium-sized UAV designed for surveillance and reconnaissance missions and noted military communication and electro-optical reconnaissance payload options. Defence Industry Europe characterized the German-delivered Primoco ONE aircraft as tactical ISR drones.
The record does not support treating the Ukrainian Primoco aircraft as armed strike systems. The cited conflict-use sources identify deliveries, recipient, and mission category, but they do not name a Ukrainian unit, provide sortie-level accounts, or document weapon release by the type.

System context in Ukrainian service
The One 150's relevance to Ukraine comes from endurance and payload capacity for battlefield information collection rather than expendable attack use. Primoco's own product material describes a runway-launched unmanned aircraft with autonomous takeoff and landing, up to 15 hours endurance, a 120 km/h cruise speed, and payload capacity up to 30 kg.
Those characteristics fit the foreign-aid role described in Ukraine-war sourcing: a reusable fixed-wing reconnaissance aircraft supplied by European donors for surveillance, ISR, and target-search support in a conflict dominated by drones, artillery, and air-defense pressure.
