Portuguese Navy

The Portuguese Navy is a small but modern force focused on maritime security within its vast maritime domain and contributing to collective security missions, primarily with NATO. Its maritime strategy is heavily influenced by the geography of the Atlantic Ocean, emphasizing maritime situational awareness and the security of sea lanes. Portugal's responsibilities are significant, covering a large search and rescue area and the potential for a vastly extended continental shelf, which will increase the demand for naval presence and control.

The fleet's capabilities are centered on a small number of modern surface and subsurface combatants. The submarine force, consisting of two Tridente-class (Type 214) diesel-electric submarines, provides a significant undersea warfare capability. However, recent operational availability issues have prompted considerations for modernizing and potentially expanding the submarine force, with analyses looking into acquiring new, smaller submarines to complement the existing fleet. The surface force is centered around frigates, such as the Vasco da Gama class, which are key assets for national and NATO operations.

A key area of innovation and capability development is in maritime uncrewed systems (MUS). The Portuguese Navy is a recognized leader within NATO in the development and operational integration of these technologies. This is demonstrated through initiatives like the 'REPMUS' exercises, which test and integrate various uncrewed underwater and surface vehicles into the fleet's operational concepts. The navy is actively acquiring new uncrewed surface vehicles (USVs) to enhance its operational capacity.

The operational reach of the Portuguese Navy is concentrated on the North Atlantic, where it conducts patrols and surveillance. However, it also has a global commitment to monitor and protect Portuguese-flagged merchant vessels. As a dedicated NATO member, Portugal regularly commits its naval assets to Alliance missions, demonstrating an operational capability that extends into the Mediterranean and other areas of interest to NATO.
