Spain Deploys Largest Naval Group of the Year to US Coast. The Spanish military has launched a major naval operation: five ships and 2,500 personnel have departed for the US. The group will take part in NATO exercises and celebrations in New York. Ahead lies a key mission for Atlantic security.
Spain has deployed its largest naval contingent of 2026: five ships and about 2,500 military personnel have already set sail into the Atlantic and are heading towards the eastern coast of the United States. This mission is part of the Despliegue Atlántico 26 expeditionary combat group and will be the Spanish Navy's main international event this year.
The group includes the landing ship Castilla, serving as the headquarters, the multipurpose Juan Carlos I with the Fleet Projection Group command, an augmented marine battalion, the frigates Blas de Lezo and Reina Sofía, and the supply vessel Patiño. In total, more than 75 pieces of marine equipment, 12 landing crafts, and 10 aircraft are involved, including AV8B Harrier fighters, SH60 Seahawk and H135 Nival Navy helicopters, as well as HT-27 Cougar and HA-28 Tigre Army helicopters.
According to RUSSPAIN, the operation is led by Vice Admiral Juan Bautista Pérez Puig, head of the SPMARFOR staff. Over the next two months, the Spanish group will undergo combat training and integration phases with NATO allies, and will then take part in the international FleetEx250 exercises under command of the US Navy, as well as celebrations for the 250th anniversary of the country in New York.
After the events in the US conclude, the Spanish SPMARFOR headquarters will be activated as Commander Task Force Atlantic (CTF Atlantic) within the NATO structure. This will allow Spain to take on monitoring and protection duties in the North Atlantic region as part of Operation eVA Arctic Sentry, which kicks off at the start of 2026. Only six of the alliance's 32 member countries hold this status, underscoring the significance of the mission for Madrid.
A large-scale deployment of the Spanish fleet is taking place amid rising tensions in the Atlantic and NATO’s efforts to strengthen its northern flank. In recent years, Spain has been actively increasing its participation in international defense initiatives, and business interest in military projects is further evidenced by the fact that Catalan companies expect to receive up to 20% of federal investments in the defense sector — more on this can be found in the article about new alliances and plans in Catalonia.
For reference: Despliegue Atlántico 26 is the largest Spanish naval operation in recent years. As part of it, the Spanish Navy not only demonstrates its readiness for joint actions with allies but also strengthens its own ability to secure maritime communications. Given the ongoing tensions between NATO and Russia, such missions are of particular importance for all of Europe.
