Five European defence companies will test loitering munition systems this autumn at Portugal’s Santa Margarida training area, competing in the second stage of the European Defence Agency’s Sentinel Strike Challenge.

From Desk to Field

Helsing (Germany), Destinus (Netherlands), C-Astral (Slovenia), UAVision (Portugal) and Spirit Aeronautical Systems (Greece) topped a field of more than 140 expressions of interest, as per a recent press statement from the EDA. Each firm earned a €30,000 Stage 1 prize after assessment against technical maturity, operational relevance and safety criteria. A further five companies, including THALES LAS and Cerberon Defence Systems, received €10,000 each for reaching the top ten.

The five finalists now advance to EU OPEX26, an operational experimentation campaign where their systems face controlled, realistic and contested conditions. Military users from EU Member States will evaluate the drones across the full mission cycle, testing resilience and comparing performance under identical scenarios. A combined prize pool of €1,800,000 awaits the strongest performers.

Testing, Not Buying

Reaching Stage 2 carries no purchase guarantee. The Sentinel Strike Challenge remains a research exercise, not a procurement route, and offers no contracts to winners. Its aim is generating evidence that defence ministries can use when weighing future capability decisions.

The initiative reflects growing urgency around loitering munitions, a category reshaped by recent conflicts and rapid battlefield adaptation. Traditional procurement cycles struggle to keep pace with such technological change. By testing systems under military oversight before committing to development pathways, the EDA hopes to sharpen how emerging capabilities get evaluated.

Overall winners of the Sentinel Strike Challenge are expected to be announced in 2027, following the Portugal field trials.
