A partnership rooted in European autonomy is rapidly taking shape as the Old Continent grapples with the challenges posed by Russia’s hybrid war and an unstable relationship with the United States. Last week, France and Sweden solidified this strategic bond in Stockholm by signing a landmark €4.3 billion ($4.9 billion) agreement for the delivery of four Defense and Intervention (FDI) frigates to the Royal Swedish Navy: HMS Luleå, HMS Norrköping, HMS Trelleborg, and HMS Halmstad, with deliveries scheduled between 2030 and 2034.
The official ceremony, held aboard the French Navy's first-in-class frigate Amiral Ronarc’h, was attended by French President Emmanuel Macron, Swedish Prime Minister Ulf Kristersson, Director General of the Swedish Defense Materiel Administration (FMV) Mikael Granholm, and Naval Group CEO Pierre Éric Pommellet.
Simultaneously, Swedish Defense Minister Pål Jonson and his French counterpart, Minister of the Armed Forces Sébastien Lecornu, signed a bilateral framework agreement to expand long-term operational cooperation and industrial collaboration.
Advanced Combat Systems of the New Luleå-class Frigates
Although the contract signed last Monday does not include the final weapons package, the new Luleå-class frigates are expected to feature advanced, multi-layered combat systems. The vessels are expected to be equipped with:
- The Sylver A50 system: Designed for launching missiles from the Aster family, manufactured by the Franco-Italian consortium Eurosam.
- The Sylver Cold Launch system: Dedicated to deploying the CAMM-ER missile, the result of a successful collaboration between Italy and the United Kingdom.
According to reports from defense platforms like Naval News, official discussions regarding the potential supply of naval cruise missiles manufactured by MBDA have not yet begun.
Expanding Sweden’s Naval Strategy on NATO's Northern Flank
Sweden’s interest in this type of high-end military vessel should come as no surprise. With Stockholm’s recent accession to NATO, the Royal Swedish Navy has seen its mission in the Baltic Sea expand significantly, shifting from the sole defense of local territorial waters to broader regional engagements alongside allies such as Finland and the Baltic states.
The 4,000-ton FDI Luleå-class frigates perfectly meet the needs of modern naval forces that must now extend their range of operations across three key northern theaters—the Baltic Sea, the North Sea, and the High North outside the Arctic. To achieve this, the ships rely on advanced sensors and multi-layered air defense capabilities explicitly designed to counter asymmetric threats such as drones and ballistic missiles.
Balancing Uncrewed Innovation and Crewed Warship Capabilities
Similar to the United Kingdom, which has recently shifted toward a “hybrid navy” model, Sweden also wishes to acquire uncrewed surface vessels (USVs), having closely observed the rapid development and operational effectiveness of such platforms in Ukrainian operations across the Black Sea. Swedish military planners note, however, that larger crewed warships remain essential tools for protecting critical undersea infrastructure and escorting commercial vessels in times of crisis.
The decision to select a European contractor such as Naval Group demonstrates Stockholm’s intent to strengthen its Navy through cooperation with continental partners. At the same time, it opens up critical possibilities for the growing strategic relationship between Sweden and France.
The Aerospace Race for Europe’s Next-Generation Fighter Jet
In this regard, an Élysée official clarified a few days before Macron’s state visit that Paris is fully open to collaborating with Stockholm to build a next-generation fighter jet. This statement comes in the wake of the official collapse of the FCAS program with Germany and Spain and, indirectly, also involves Berlin.
In fact, Germany was the first to reach out to Sweden to develop a new fighter jet. This interest stems from Sweden’s long-standing experience in the aerospace sector, particularly through the industry giant Saab, manufacturer of the fourth-generation Gripen fighter—which Stockholm has also proposed to Canada in its advanced Gripen E variant.
Strategic Autonomy and Technological Cooperation in Aviation
France, too, has a long tradition of autonomy in the aviation industry, marked by the leading role of Dassault. However, while the Gripen’s engine uses American technology supplied by GE Aerospace, the engines for the Rafale fighters are manufactured entirely in France by Safran. Sources in Paris believe that a joint effort between two countries that share a similar, compact approach to the aerospace domain could indeed produce a relatively small aircraft ideally suited to the needs of both nations.
Nevertheless, many analysts recall the friction that plagued previous collaborations with Airbus Defence and Space, warning that the recurrence of industrial tensions and program bottlenecks cannot be ruled out.
A decision regarding Sweden's national program to develop a new fighter jet is expected by next year, and European partners have already begun actively courting Stockholm.
