Marinha Portuguesa monitors the passage of the Russian vessel “URSA MAJOR” through Portuguese waters.

The Portuguese Navy announced that it had tracked the Russian-flagged ship URSA MAJOR through the continental section of Portugal’s EEZ between Sunday and Monday, deploying patrol vessels NRP Setúbal, NRP Orion and NRP Dragão to accompany the vessel during its transit. The Navy described the ship as actively participating in Russian logistical resupply operations, signalling its possible role in sustaining Russian naval deployments. The event highlights how Portugal’s Atlantic littoral — far from the immediate Russia-Ukraine front — is part of the maritime domain in which Russia projects presence. The dynamics show that Russia uses logistical and non-combatant vessels to traverse allied maritime zones, thereby gaining proximity, mapping sea-lanes and under-sea infrastructure, and compelling allied forces to divert resources to tracking. Although no direct sabotage or kinetic attack was reported, the passage itself elevates monitoring burdens and signals the use of naval logistics assets in grey zone operations. The incident underscores the strategic vulnerability of even Western-European maritime zones to Russian naval presence and deep-sea capabilities.
