Sweden’s French frigates purchase marks one of Stockholm’s largest defence investments in decades, as the government moves to strengthen naval air defence, NATO interoperability and maritime security in the Baltic Sea after Sweden’s entry into the Alliance.
The Swedish government announced that it will acquire four FDI-type frigates from France’s Naval Group, with deliveries expected to begin in 2030 and continue at a pace of one vessel per year. Prime Minister Ulf Kristersson described the decision as one of the country’s biggest military investments since the introduction of the Gripen fighter jet in the 1980s.
The ships will be built in Brittany by the French company Naval Group and adapted to Swedish requirements, including the integration of domestic systems from companies such as Saab and Bofors. According to Defence Minister Pål Jonson, each vessel is expected to cost around SEK 10 billion, about €910 million, bringing the programme to at least SEK 40 billion, or roughly €3.7 billion, before the final configuration is confirmed.
French FDI frigates give Sweden a floating air-defence shield
The new vessels will be significantly larger than Sweden’s current Visby-class corvettes. While the Visby ships are around 72 metres long and designed mainly for operations close to Sweden’s coast, the French-built frigates are expected to be around 120 metres long and capable of operating in wider NATO missions.
The most important shift is air defence. The frigates will carry advanced missile systems, including the Franco-Italian Aster 30 and European CAMM-ER, giving Sweden the ability to protect not only the ship itself, but a wider area against aircraft, missiles and drones. Swedish officials said this would amount to a tripling of the country’s naval air-defence capacity.
Commander-in-Chief Michael Claesson said the new vessels would give Sweden capabilities it does not currently have at sea, comparable in some respects to land-based systems such as Patriot. The frigates are also expected to combine anti-submarine warfare, anti-ship missiles, naval guns and command functions, allowing them to protect sea routes and lead maritime operations.
Why Stockholm chose Naval Group over other European bids
Speed was a central factor in the Swedish decision. Jonson said the French offer was based on an existing design with high delivery reliability and a proven integrated air-defence system. The first frigate is planned for delivery in 2030, with one additional ship arriving each year after that if negotiations proceed as expected.
The choice follows an international assessment by the Swedish Armed Forces and the Defence Materiel Administration (Försvarets materielverk, FMV), which reviewed available designs against Sweden’s requirements. The French option was selected over competing proposals, including bids linked to the United Kingdom and Spain.
The government also stressed that the ships will not be purely off-the-shelf purchases. Sweden will require the integration of Swedish weapons and sensor systems, including Saab’s RBS 15 anti-ship missile, Torpedo 47, Trackfire remote weapon station and Giraffe radar, as well as Bofors automatic cannons. Maintenance is also expected to take place at a Swedish shipyard.
This industrial element is politically important. It allows the government to present the purchase not only as an urgent military acquisition, but also as a way to preserve Swedish defence-industry participation in a major European programme.
The Baltic Sea becomes the centre of Sweden’s NATO role
The decision comes as Sweden continues to redefine its defence posture after joining NATO in 2024. For decades, Swedish naval planning focused primarily on territorial defence and operations in nearby waters. The new frigates point to a broader role: protecting shipping, supporting allied operations and contributing to NATO’s maritime presence in the Baltic Sea and beyond.
Kristersson said the investment would make the Baltic Sea significantly safer. The argument reflects a wider regional concern. Russia’s full-scale invasion of Ukraine has changed security planning across Northern Europe, while sabotage risks against undersea cables, energy infrastructure and maritime routes have pushed NATO members to reinforce naval surveillance and deterrence.
For Sweden, the Baltic Sea is no longer only a national security space. It is also a shared NATO theatre linking Sweden, Finland, Denmark, Poland, Germany and the Baltic states. Larger ships with stronger air-defence systems allow Stockholm to contribute more visibly to collective defence, including missions outside its immediate coastline.
A deeper Swedish-French defence relationship, but not a nuclear deal
The frigate decision also strengthens Sweden’s defence relationship with France. Paris has promoted closer European defence cooperation and has recently opened strategic dialogues with European partners on deterrence, including nuclear deterrence.
Jonson, however, rejected the idea that the frigate purchase was linked to Sweden’s dialogue with France on nuclear issues. He said the procurement decision was based on military requirements, delivery speed and the maturity of the French design.
The industrial relationship may still expand. France is reportedly interested in acquiring Saab’s GlobalEye airborne early warning and control aircraft, a possible parallel deal that would further deepen cooperation between the two countries. For Stockholm, this creates a defence-industrial balance: Sweden buys French ships, while Swedish systems remain part of the package and may gain new export opportunities.
Critics say Sweden is buying costly ships in a drone war era
The purchase has also drawn criticism. Jacob Ämtvall, a security expert at the business organisation Företagarna, described the deal as a strategic mistake, arguing that Sweden risks concentrating too much money in a small number of expensive platforms.
His criticism reflects a broader debate across Europe after the war in Ukraine. Drones, cheap sensors and rapidly adaptable technologies have shown how smaller systems can challenge traditional military platforms. Critics argue that future defence planning should prioritise flexibility, innovation and closer cooperation with small technology companies.
The government’s counterargument is that Sweden needs both. Large frigates cannot replace drones or distributed defence systems, but drones cannot provide area air defence, command capacity or long-range maritime protection in the same way. The Swedish decision therefore reflects a choice to invest in high-end capabilities that support NATO operations, while still integrating national systems and future upgrades.
Sweden’s navy returns to large surface warships
Sweden has not operated warships of this scale since its last destroyers were withdrawn from service in the late 1970s and 1980s. The new Luleå-class frigates will therefore mark a structural change for the Swedish Navy.
The move also fits into a broader increase in Swedish defence spending. The government has pledged to raise military expenditure sharply in response to Russia’s threat and NATO requirements. The frigate programme is one of the most visible symbols of that shift: expensive, long-term and designed for a security environment in which Sweden sees itself as both a Baltic power and a full NATO ally.
The final cost will depend on weapons, sensors, maintenance arrangements and the outcome of negotiations between FMV, French authorities and Naval Group. But the political message is already clear. Sweden is moving from coastal defence towards a larger, more integrated naval role in Northern Europe, with French frigates at the centre of its future maritime strategy.
