What advantage does Naval Group's Jean-Marie Dorbon say Sweden gains by joining the existing FDI programme?

According to FDI programme director Jean-Marie Dorbon, Sweden inherits a risk-free solution by joining a programme in which the first two frigates have already been delivered to the French and Hellenic navies. The fine-tuning identified during those deliveries was carried out by previous customers, meaning Sweden benefits directly from series effects. Dorbon describes this as the single most important advantage for Sweden. Last fact-checked: 2026-05-20.

How does the Swedish FDI order affect the production rate at Naval Group's Lorient shipyard?

Without the Swedish order, the Lorient shipyard would be building one frigate per year, but with the Swedish order it builds two frigates per year. Dorbon states this increased rate is not a problem and that the Swedish order stabilises rather than disrupts production. France ordered its fifth FDI in March 2026 and Greece its fourth in November 2025, reflecting a growing order book. Last fact-checked: 2026-05-20.

What is the minimum number of FDI frigates in the Swedish order and could additional units be added?

The current Swedish order stands at a minimum of four FDI frigates. When asked whether options exist for additional units, Dorbon gave an open-ended response, stating that Naval Group is able to answer the demand of the client. This suggests the order could be expanded beyond four vessels depending on Swedish requirements. Last fact-checked: 2026-05-20.

Why does Naval Group need additional industrial partners to expand FDI production beyond two frigates per year?

Dorbon explains that scaling production beyond the current rate requires additional industrial partners to be brought in. He points out that blocks for the Hellenic and French frigates are already being produced in Greece, illustrating how components can be manufactured at other locations with final assembly in Lorient. This geographical division of hull and integrated superstructure production is described as a way to accelerate delivery capacity. Last fact-checked: 2026-05-20.

How does Naval Group ensure FDI interoperability with Sweden's existing Visby-class corvettes?

Dorbon states that cooperation with Saab is central to ensuring that crews accustomed to other platforms can operate the FDI frigates. He also notes that Sweden has adopted NATO standards for tactical data links, which technically facilitates interoperability with the Visby-class corvettes already operated by Sweden. In his formulation, technical standards ensure the vessels work together while the Saab cooperation ensures personnel can operate them. Last fact-checked: 2026-05-20.

When does Jean-Marie Dorbon say Naval Group could deliver additional FDI frigates if production is scaled up?

Dorbon states unambiguously that Naval Group could begin delivering additional FDI frigates from 2030 if production is scaled up, but that new industrial partners would need to be added to achieve this. He explicitly clarifies in a follow-up exchange that he means deliver, not begin production, in 2030. He rules out delivering three frigates as early as 2027, making 2030 the earliest realistic expanded delivery date. Last fact-checked: 2026-05-20.

Naval Group: 'Sweden inherits a risk-free solution'

At the shipyard in Lorient, Naval Group launched the second French FDI frigate, Amiral Louzeau – the same vessel class that Sweden will receive as the Luleå-class from 2030. On site, NDS interviewed Jean-Marie Dorbon, director of the FDI programme, about what Sweden gains from joining an ongoing programme, what is required to keep the schedule, and how production can be scaled up.

Sweden is choosing to join a programme in which the first two frigates have already been delivered to the French and Hellenic navies. NDS visited the Naval Group ship yard in Loriant, and spoke with Jean-Marie Dorbon, FDI programme director at Naval Group, who describes this as the single most important advantage for Sweden.

– The advantage of joining an existing programme is that you inherit a risk-free solution. We have now delivered the first two frigates to two different navies, the French and the Hellenic. As the chief of the French naval staff said, there is still some fine-tuning to be done, but the work on that fine-tuning was carried out by previous customers. Sweden will benefit directly from the series effects, says Dorbon.

He further describes how the shipyard in Lorient (western France) is engaged in a continuous industrial process in which the production rate can be adjusted according to the order situation.

Swedish systems within the design framework

When asked about the integration of Swedish systems such as RBS15, Torpedo 47, Saab sensors and Bofors guns, Dorbon states that the FDI was designed from the outset with space to add sensors, weapons and other systems. He notes that the French Navy now wishes to add additional missile launchers to the vessel Amiral Ronarc'h.

– We have a common FDI core built around two major systems, primarily the air defence system and the anti-submarine warfare sensors, says Dorbon.

Interoperability with the Visby-class corvettes

Dorbon states that cooperation with Saab is part of the work to ensure that crews accustomed to other platforms will be able to operate the vessels. He notes that Sweden has adopted NATO standards for tactical data links, which facilitates interoperability with the Visby-class corvettes already operated by Sweden.

– The technical standards ensure that the vessels will work together. The cooperation with Saab ensures that the personnel will be able to operate them, says Dorbon.

Growing order book, but a minimum of four vessels for Sweden

France ordered its fifth FDI in March 2026 and Greece its fourth in November 2025. Dorbon argues that the Swedish order does not conflict with other customers but rather stabilises the production rate.

– Without the Swedish order, the shipyard would be building one frigate per year. With the Swedish order, the shipyard builds two frigates per year. That is not a problem, says Dorbon.

When asked whether the Swedish order is limited to four vessels or whether options exist for additional units, Dorbon gives a response that opens the door to an expanded order.

– Today it is four, but of course we are able to answer the demand of the client, says Dorbon.

Scaling requires new partners, and the question of Denmark

When asked about a potential Danish order, Dorbon is clear that expanded production beyond the current rate requires additional industrial partners to be brought in. He points out that blocks for the Hellenic and French frigates are already being produced in Greece, and that industrial capacity can be expanded by having partners produce components at other locations, with final assembly in Lorient.

– If you ask whether I can deliver three frigates in 2027, the answer is no. If you ask whether we can begin increasing production from 2030, the answer is yes, but we will need to add partners, says Dorbon.

When asked in a follow-up question whether he is referring to beginning production or delivering in 2030, the answer is unambiguous.

– Deliver. Deliver in 2030, says Dorbon.

He describes how Naval Group builds the hull and integrated superstructure separately, which opens the possibility of a geographical division of production.

– Today we produce both parts in Lorient. Tomorrow we can envisage producing one part elsewhere and carrying out the final integration here. That is also a way to accelerate, says Dorbon.
