Stockholm chooses French FDI frigates as Naval Group wins Sweden’s largest naval program in decades

Sweden has selected the French FDI frigate design for its future surface combatant program, choosing Naval Group over the British Arrowhead 120 and a proposal from Spain’s Navantia. Stockholm opted for a platform already under construction and approaching operational service, with air defence capabilities and delivery timelines emerging as decisive factors in the competition. The decision marks a major shift in Swedish naval planning following the country’s accession to NATO and highlights the growing strategic importance of the Baltic Sea.

"One of Sweden’s largest defence investments"

The decision follows months of evaluations conducted by the Swedish Defence Materiel Administration (FMV). Three European contenders remained in the final stage of the competition: the French FDI from Naval Group, the British Arrowhead 120 offered by Babcock International, and a proposal submitted by Navantia.

Ultimately, Stockholm selected what Swedish officials described as the most mature and lowest-risk option.

Swedish Prime Minister Ulf Kristersson described the future frigate acquisition as one of the country’s most significant defence investments in recent decades.

– This is one of the largest defence investments currently being undertaken by Sweden. The new frigates will significantly strengthen our air defence capabilities and our ability to protect maritime lines of communication – Ulf Kristersson said during the official announcement.

The statement reflects the broader strategic context behind the program. Swedish officials increasingly view the Baltic Sea not simply as a regional operating environment, but as a key NATO theatre requiring persistent naval presence and integrated air defence capabilities.

Air defence capability became the decisive factor

Swedish Defence Minister Pål Jonson repeatedly stressed that advanced air defence capabilities were central to the selection process.

– Advanced air defence was one of the decisive elements in this decision – Pål Jonson stated following the announcement of the FDI selection.

The French frigate design is built around the Thales Sea Fire AESA radar and the Aster family of surface-to-air missiles, providing area air defence capabilities against aircraft, cruise missiles and complex aerial threats.

For the Swedish Navy, the acquisition represents a substantial doctrinal evolution. Until now, the core of Svenska Marinen consisted primarily of smaller surface combatants optimized for littoral warfare, including the Visby-class corvettes. The future Luleå-class frigates will instead provide long-range escort, anti-submarine warfare and fleet air defence capabilities suitable for operations both inside and beyond the Baltic region.

Sweden prioritized a design already in production

One of the strongest advantages of the French offer was the maturity of the FDI program itself. The lead ship for the French Navy has already been launched and is currently undergoing sea trials, while additional units are under construction for both France and Greece.

According to Admiral Johan Norlén, Chief of the Swedish Navy, minimizing technological and scheduling risk was a critical consideration.

– We need a ship that can be delivered within a predictable timeframe. We cannot afford extensive delays or a program requiring years of additional development – the admiral said in comments cited by defence media.

The statement illustrates a broader trend across European navies following the war in Ukraine and growing tensions in Northern Europe. Operational readiness and delivery speed increasingly outweigh the appeal of ambitious but immature naval programs.

Naval Group emphasizes long-term industrial cooperation

- We are extremely honoured to have been selected by the Swedish Ministry of Defence. We are now eager to engage with the Swedish authorities and partners in the execution of this strategic project. The FDI will provide the Royal Swedish Navy with a latest-generation frigate and extended capabilities in all warfare domains with rapid delivery timeline, to meet the operational needs expressed by the Ministry of Defence. This selection also reinforces our strategic partnership with Sweden and shows the strength of industrial cooperation in Europe. We are proud to contribute to securing Europe - said Pierre Éric Pommellet, Chairman and CEO of Naval Group.

Naval Group has consistently presented its proposal as more than a straightforward shipbuilding contract. In recent months, the French company expanded its industrial engagement in Sweden, including agreements related to support, sustainment and lifecycle maintenance.

– This is a strategic partnership that will help develop local competencies and ensure support for the frigates throughout their operational life – said Guillaume Weisrock of Naval Group during the signing of an agreement with Swedish shipyard Öresund Drydocks.

The future Swedish configuration is also expected to incorporate significant domestic content. Swedish industry is likely to integrate several nationally developed systems, including Saab solutions, RBS15 anti-ship missiles, Torped 47 lightweight torpedoes and the Bofors 57 mm naval gun.

What capabilities will Sweden receive?

The FDI is a next-generation multi-role frigate measuring approximately 122 meters in length with a displacement exceeding 4,400 tons. The platform was designed for high-intensity naval warfare, with a strong focus on air defence and anti-submarine operations.

Key systems include:

• the Sea Fire AESA radar,
• the SETIS combat management system,
• CAPTAS-4 Compact sonar,
• vertical launch systems for surface-to-air missiles,
• facilities for embarked helicopters.

The first Swedish frigate is expected to enter service around 2030. Stockholm plans to acquire four ships under the program, with the total value estimated at approximately €3.7–4.3 billion.

A setback for Britain and a signal for European naval procurement

The Swedish decision represents a significant setback for the British naval industry. Arrowhead 120 had been regarded as a politically attractive option due to the close defence relationship between Stockholm and London, as well as potential industrial links with Poland’s Miecznik frigate program.

However, Sweden ultimately prioritized operational maturity and integrated air defence capabilities over developmental potential.

The outcome also reflects changing priorities in European naval procurement. The Baltic Sea is becoming an increasingly contested operational environment saturated with anti-access systems, missile threats and electronic warfare capabilities. In such conditions, navies are placing growing emphasis on survivability, integrated air defence and rapid availability of combat-ready platforms.

That strategic reality appears to have been decisive in Stockholm’s selection of the French FDI frigate.
