Between the announcement by the Swedish Ministry of Defence of the selection of the Defence and Intervention Frigate (FDI or Ronarc'h class) and the start of construction of the first of the four units ordered, barely five months have passed. In terms of arms programs, such a short timeframe is quite rare and worth noting. On 2 October, Naval Group, a major French shipbuilder, announced that the steel-cutting ceremony for the Luleå frigate had taken place in Lorient, France. Rear Admiral Fredrik Lindén, head of naval systems at the Swedish Defence Materiel Administration (FMV), presided over the event. This occurred despite the contract, valued at 4.3 billion euros, having been signed only on 31 August. Vincent Martinot-Lagarde, head of the "surface ships" division at Naval Group, stated that all sites and teams are fully committed to the success of the program, working closely with the FMV in both France and Sweden. He emphasized that the company is capable of delivering two FDI units per year thanks to investments in its Lorient shipyard—15 million euros annually since 2020—and the use of digital tools and automation to increase production capacity. Additionally, alongside the construction of the hull using a modular method, Naval Group is assembling the integrated mast, known as the PSIM (Panoramic Sensors and Intelligence Module), which functions as the "brain" of the ship. This allows for the testing of various systems (radars, sensors, and combat management systems) before the first sea trial, saving valuable time. The General Directorate of Armaments (DGA) has taken a proactive approach by financing "white hulls"—essentially empty ship frames—before actual orders are finalized. This is how the DGA notified Naval Group of contracts for the fourth and fifth French FDI units, expected to be delivered in December 2025 and March 2026, respectively. However, the French Navy does not anticipate receiving these ships before 2032 at the latest. This strategy, explained by Emmanuel Chiva, then General Delegate for Armaments, during a parliamentary hearing in October 2025, aims to "optimize the production schedule, reduce costs, and make the equipment immediately available for an export customer." Regardless of these early commitments, Naval Group insists that the production line remains fully operational, with new delivery slots available in 2030. This is a clear message directed at Denmark, where the French industrialist is competing with the British company Babcock to deliver four frigates. With thirteen FDI units having been ordered to date—five by France and four by Greece—Naval Group is demonstrating its capacity to maintain a steady production schedule while responding to international demand.
