Two Russian naval vessels are monitored sailing close to Portugal’s maritime zone.

The Portuguese Navy announced that it had closely monitored the Russian ships as they transited through or near its Exclusive Economic Zone (EEZ) during 15–17 December. The Portuguese Maritime Operations Center coordinated deployment of vessels such as the frigate NRP D. Francisco de Almeida and patrol craft to track the Russian units. The geography underscores how Portugal’s maritime approaches are being used by Russian naval assets, suggesting that even Western-flank states are within the maritime “grey zone” of hybrid-threat operations. The dynamics reveal how the presence of Russian naval assets near Portuguese waters could serve reconnaissance, signalling and potential preparation for future operations (such as under-sea infrastructure monitoring). Although no sabotage or physical strike on Portuguese territory was reported, the incident demonstrates how navies can exert pressure without overt violence and still qualify as hybrid-warfare activity. Notably, Portugal’s monitoring effort illustrates awareness of these tactics and the burden placed on smaller naval forces to track multiple foreign vessels in their maritime zones.
