Portuguese navy strengthens Madeira’s security amid increased Russian activity
Portugal is ramping up its military presence in the Madeira region by deploying additional patrol vessels. This decision is a direct response to the growing activity of Russian naval units near the Portuguese archipelago, particularly concerning the protection of undersea telecommunications cables. But does the marinha portuguesa have sufficient capabilities to effectively monitor the situation in the Atlantic?

Russian warships near Madeira – cause for concern?
In recent months, an increase in the presence of Russian vessels has been observed not only near Polish critical infrastructure but also in the vicinity of Madeira. Intelligence-gathering ships, in particular, raise alarms as they may be involved in activities targeting undersea infrastructure. The critical communication and internet lines running along the Atlantic seabed represent a strategic asset, and any potential threat to them demands a response from Portugal and its NATO allies.
Currently, the region's security is entrusted to the patrol vessel NRP Zaire. Previously, NRP Mondego was also deployed in the area, but technical issues have rendered it inoperable. The Portuguese navy now plans to bolster patrols by dispatching two additional vessels to the Madeira region. This move aims both to deter potential threats and enhance situational awareness.
Portuguese navy – current capabilities
Despite its relatively small size, the marinha portuguesa operates modern vessels well-suited for Atlantic operations. Its core assets include Bartolomeu Dias-class and Vasco da Gama-class frigates, equipped for anti-air and anti-submarine warfare. Additionally, João Coutinho-class corvettes and numerous patrol vessels are utilized for coastal protection and maritime security operations against illegal activities.
As a NATO member, Portugal closely collaborates with allied forces to ensure maritime security. Beyond its own fleet, Portugal can rely on the support of NATO units, which is particularly crucial given Russia’s increasing presence in the Atlantic region.
Portuguese navy’s training ships – tradition and education
The Portuguese navy also operates training ships that play a vital role in preparing future naval officers. The most renowned among them is NRP Sagres, a three-masted tall ship serving both as a training vessel and a global ambassador for Portugal. This historic sailing ship frequently participates in international regattas and events, showcasing the country’s maritime heritage.
Alongside NRP Sagres, the Portuguese naval training fleet includes smaller vessels used for hands-on cadet training at the naval academy. Practical experience gained aboard these ships provides future officers with crucial navigation skills, essential for their later service on modern warships.
Does Portugal have adequate forces to protect Madeira?
Strengthening the Portuguese navy’s presence in the Madeira region is a step in the right direction, yet concerns remain regarding the adequacy of these measures. Continued observation of Russian maneuvers in the area will be critical, as will the ongoing modernization of Portugal’s naval forces. Given the rising geopolitical tensions, Portugal must be prepared for swift and effective action to safeguard its strategic interests in the Atlantic.
It is also possible that, following the model of Baltic Sentry, NATO may increase its naval presence in the Atlantic, conducting joint patrols to secure the critical infrastructure of alliance members.
