The French Navy is about to field its full fleet of giant amphibious assault ships at the same time, a move that signals ambition, confidence, and a busy year ahead on the high seas.
Three French giants heading back to sea
France’s trio of Mistral-class amphibious assault ships – Mistral, Tonnerre and Dixmude – are preparing a rare simultaneous deployment. All three are based in Toulon, on the Mediterranean coast, and are regarded as central tools of France’s power projection strategy.
These vessels are often described as “helicopter carriers”, but their role goes far beyond operating rotorcraft. Each ship can carry troops, armoured vehicles, landing craft, a full command staff and a mixed air group, acting as a floating base for crisis response, combat operations or humanitarian missions.
French amphibious helicopter carriers are at sea between 180 and 200 days a year, placing them among the most heavily used assets in Europe.
The current plan brings together three different storylines: high-end officer training, a large multinational exercise, and a political-military signal to allies and rivals alike, from the Mediterranean to the Baltic Sea.
Operational performance as a political signal
For the French Navy, showing that all three “Bâtiments de projection et de commandement” (BPC) are ready to sail at short notice matters almost as much as the missions themselves. High availability has become a metric closely watched by partners and competitors.
Crews on these ships typically spend roughly half the year away from home. That tempo demands constant maintenance, careful scheduling and a rotation of personnel. It also gives France the ability to react quickly to emerging crises – evacuating civilians, landing troops or leading multinational task groups.
Regular and lengthy deployments turn ships into political tools: they show up where decisions are made, not only where battles are fought.
In a context marked by tensions with Russia, growing instability in parts of Africa and the Middle East, and renewed focus on the Indo-Pacific, Paris is using its large deck ships to demonstrate that it remains a “blue-water” navy able to operate far from its shores.

The Dixmude and the Jeanne d’Arc mission
A floating classroom with a combat edge
The first of the three to depart will be Dixmude, scheduled to launch this year’s “Jeanne d’Arc” mission before mid-February. This long-running deployment is both a rite of passage and a live operational tour for newly commissioned French officers.
On board, naval, army and sometimes air force trainees will rotate through watches, planning cells and landing operations. A light stealth frigate will accompany Dixmude, providing extra sensors and protection, and turning the formation into a compact but credible task group.
Recent drills in Toulon focused on the embarkation of two Écume fast craft used by the elite Commando Hubert special forces. That choice hints that the Jeanne d’Arc cruise will not be limited to basic navigation and protocol visits. Instead, the mission is expected to feature complex scenarios: hostage rescues, littoral raids or reconnaissance operations staged with partner nations.
The Jeanne d’Arc deployment blends officer training with real-world presence, giving young leaders their first taste of power projection.
The exact itinerary still has not been publicly confirmed, which is common for such missions. Previous editions have taken French cadets to the Indian Ocean, the Pacific, or the Caribbean, mixing cooperation with local navies and port calls that carry a strong diplomatic flavour.
Tonnerre and Mistral gear up for Orion 26
A large-scale test of allied forces
While Dixmude heads off on Jeanne d’Arc, sister ships Tonnerre and Mistral are assigned to “Orion 26”, a major inter-allied exercise scheduled in stages across France and surrounding seas. The drill is designed to test how French and partner forces would conduct a high-intensity campaign against a near-peer adversary.
On 26 January, one of the two ships embarked around six helicopters – a mix of lightweight Gazelle attack/scout platforms and heavy NH90 “Caïman” tactical transports. Those aircraft will support simulated landings, air assault missions and logistics runs between ship and shore.
- Gazelle: small, agile helicopter suited for reconnaissance and light attack.
- Caïman (NH90): larger multi-role helicopter used for troop transport, support and naval operations.
- Landing craft: carried in the well deck to put vehicles and marines on the beach.
For Tonnerre, Orion 26 is the priority. The ship will serve as a command node and a platform for joint operations, integrating digital networks, drones, helicopters and land units. The crew must manage simultaneous aviation activity, amphibious movements and staff planning, all under the simulated pressure of enemy threats.
Mistral heads toward the Baltic Sea
Mistral will initially support Orion 26 preparations, then peel away on a separate trajectory toward the Baltic Sea. That region has become a strategic hotspot for NATO, especially since Sweden and Finland have deepened their cooperation with the alliance and tensions with Russia have solidified.
A French amphibious assault ship in the Baltic sends a clear signal of solidarity to eastern and northern European allies. The ship can host multinational staffs, serve as a flagship for smaller navies, and provide a mobile base for helicopters and marines during NATO activities.
Mistral’s deployment to the Baltic underlines France’s intent to remain a visible and reliable contributor to NATO deterrence.
For local partners, training alongside a large deck French vessel offers practice in coordinating air, sea and ground assets, using secure communications, and rehearsing reinforcement of exposed regions from the sea.
What makes the Mistral-class so valuable?
The Mistral-class ships are designed as multi-mission platforms. They rarely do just one thing at a time. A single deployment can mix embassy support, amphibious drills, humanitarian assistance and high-level visits.
| Capability | Role for French operations |
|---|---|
| Flight deck and hangar | Operate multiple helicopters for assault, evacuation and logistics. |
| Well deck | Launch landing craft and amphibious vehicles for beach landings. |
| Command facilities | Host joint headquarters with advanced planning and communication tools. |
| Hospital area | Provide medical care during combat and disaster relief missions. |
This flexibility explains why the ships rack up so many days at sea each year. They are used for evacuating nationals from crisis zones, delivering aid after natural disasters, or supporting counter-terrorism operations in coastal regions.
Key terms and what they really mean
The French acronym “BPC” – for Bâtiment de projection et de commandement – sums up the concept behind these ships. “Projection” refers to their ability to move forces quickly across oceans and put them ashore. “Command” highlights their role as a floating headquarters for joint or coalition operations.
Another term that shapes these deployments is “interarmées” – roughly “joint forces”. It signals that the ship is not just about the Navy. Army commandos, air force controllers and sometimes gendarmes or civilian specialists join the crew. The Jeanne d’Arc mission and Orion 26 both rest on this mix of skills.
Scenarios that French planners have in mind
Exercises such as Orion 26 are not random shows of force. They rehearse concrete situations. One scenario could involve a fast-moving crisis on the eastern flank of Europe, where a hostile state pressures a smaller neighbour. An amphibious ship like Tonnerre brings marines, helicopters and a headquarters to support a NATO response.
Another scenario might concern a sudden coup or civil conflict in a coastal African state where French citizens live and work. A Mistral-class ship could sail close to the coast, launch helicopters and landing craft to evacuate people, while also serving as a floating embassy and medical hub.
These ships also feature in disaster relief planning. After a cyclone or earthquake in an island region, a large deck vessel brings generators, fresh water, engineering teams and medical staff. The same tools that support combat landings can open roads, repair ports and treat casualties.
Risks, strain and long-term questions
Keeping three such complex ships at high readiness comes with risks. The more days at sea, the bigger the pressure on crews and equipment. Fatigue, retention challenges and maintenance backlogs can quietly erode performance if not managed carefully.
French defence planners must balance near-constant deployments with modernization. Discussions already focus on the next generation of amphibious ships and on adapting existing vessels for new threats, such as long-range anti-ship missiles or cyber attacks against onboard networks.
For now, though, the message is straightforward: France intends to make full use of its “giants of the sea”. With Dixmude, Tonnerre and Mistral all heading back to sea, the French flag will remain a regular sight on the horizon in 2026, from officer training circuits to front-line NATO exercises.
