The partnership focuses on the production of Unmanned Surface Vehicles (USVs), which have proven effective against Russian warships and submarines. Oleksandr Kamyshin, an advisor to President Zelenskyy, noted that these drones would not only bolster Ukraine's defense capabilities but also assist Portugal in safeguarding European maritime interests. Zelenskyy highlighted the necessity for all parts of Europe to possess adequate defense capabilities, asserting that modern drones are essential tools for contemporary defense strategies.

This agreement builds on a previously established bilateral security framework, which includes a 10-year security agreement signed in May 2024. Under this framework, Portugal committed to ongoing military support for Ukraine, contributing to NATO's Prioritized Ukraine Requirements List (PURL) to facilitate the acquisition of U.S.-made weapons. Zelenskyy expressed gratitude for Portugal's financial support, which includes a substantial €90 billion security guarantee for Ukraine over the coming years.

While the partnership has been largely welcomed, some critics argue that the focus on military production could divert resources from humanitarian needs in Ukraine. Concerns have also been raised about the long-term implications of increased military collaboration with NATO allies, particularly regarding regional stability.
