Greece's purchase of unmanned surface vessels (USVs) from Ukraine has stalled because Kiev demanded the platforms not be used against Türkiye. Per Haber7, Greece — which has fallen behind Türkiye in unmanned aerial and naval systems — turned to Ukraine to close the maritime capability gap. In ongoing talks under the November 2025 unmanned surface vessel production agreement signed between Ukraine and Greece, friction emerged when Ukraine insisted on retaining a say over how the platforms would be used.
The Athens side reportedly attributes the friction to the Türkiye factor. Greek sources indicate that Ukraine is concerned about the USVs potentially being deployed against Türkiye; that Kiev does not want unmanned naval platforms used against the country it considers a friend, and that it therefore demands an end-use clause covering the geographies of deployment. Ukraine's desire to preserve its partnership with Ankara outweighs the commercial priorities of the export deal, the report said.
From a supply chain and defense industry standpoint, the development matters on three fronts. First, as the USV class scales rapidly in the global market on the back of Black Sea combat experience, this is an early signal that end-use restrictions will become a permanent sub-layer of export contracts — buyers must factor not just price and delivery schedule but also the producing state's geopolitical preferences. Second, Greece's effort to close the Türkiye-centric capability asymmetry in unmanned systems is making NATO-internal defense procurement flows progressively more complex, redrawing balances of port security, sea-lane management and military-commercial transit across the Aegean and the Eastern Mediterranean. Third, Ukraine's Bayraktar TB2 + UAV production line + maritime supply chain partnership with Türkiye continues to operate as a strategic filter on Kiev's export decisions of considerable commercial weight — a measurable indicator of the supplier-loyalty advantage Türkiye's defense industry now enjoys.
Key Takeaways:
1. Ukraine-Greece USV sale stalled because Kiev demanded the platforms not be used against Türkiye.
2. The deal builds on a November 2025 unmanned surface vessel production agreement.
3. Ukraine is asking for an end-use clause covering deployment geographies.
4. Athens believes the friction stems from the Türkiye factor; Ukraine is prioritizing partnership ties with Ankara.
5. Industry signal: end-use restrictions are becoming a permanent contract layer in USV exports.
