Sweden Orders Four FDI Frigates From France in Naval Group Contract

Sweden’s Defence Materiel Administration (FMV) has signed a formal procurement contract with French shipbuilder Naval Group for four FDI-class (Défense et Intervention) frigates. The deal was signed on August 31, 2026, aboard the French Navy’s lead FDI vessel, Amiral Ronarc’h, in a ceremony attended by French President Emmanuel Macron and Swedish Prime Minister Ulf Kristersson.

At a Glance

The four frigates will enter Swedish Navy service under the local designation Luleå-class.
The contract was signed by FMV Director-General Mikael Granholm and Naval Group Chairman and CEO Pierre Éric Pommellet, with Swedish Defence Minister Pål Jonson and French Armed Forces Minister Catherine Vautrin present.
Delivery schedule: HMS Luleå in 2030, HMS Norrköping in 2032, HMS Trelleborg in 2033, and HMS Halmstad in 2034.
Air defense will rely on Aster 30 and CAMM-ER missiles fired from SYLVER A50 and SYLVER cold-launch vertical launch systems.
Sweden is integrating its own systems: the RBS15 anti-ship missile, Torpedo 47, Giraffe 1X radar, 57mm/40mm guns, and the Trackfire remote weapon station.

Background

France’s FDI program is a multi-role frigate family designed for both the French Navy and export customers; the lead ship, Amiral Ronarc’h, was delivered to the French Navy in late 2025, and Greece has separately ordered three FDI vessels. Sweden’s NATO accession in 2024 expanded its naval operating area to cover the Baltic Sea, North Sea, and High North, creating demand for blue-water air-defense capability beyond its existing corvette-heavy fleet. At the signing, Defence Minister Jonson said the four frigates “will triple Sweden’s current air defense capability.” President Macron noted that “France is not merely delivering ships — it is also providing capability to protect our friends’ territories.” Swedish Navy commander Admiral Norlén summarized the operating philosophy as “uncrewed where possible, crewed where required.”

Regional Impact

The agreement directly affects the NATO naval balance in the Baltic Sea at a time of heightened Russian maritime activity in the region; adding four frigates that triple Sweden’s air-defense capacity reinforces the alliance’s northern flank. The deal is also a notable export win for France’s FDI family, following Greece’s earlier order, and shows how NATO navies are moving toward multi-role, air-defense-focused frigates as their new baseline requirement — a trend that shapes the competitive landscape for every shipbuilder pursuing similar frigate programs internationally.
