French ship combined military training, naval diplomacy, and embarked aviation for almost half a century, becoming one of the most recognized platforms of the Marine Nationale and helping to consolidate the use of helicopters in oceanic, humanitarian, and operational missions far from Europe.
The French helicopter carrier Jeanne d’Arc, identified by the call sign R97, combined for 46 years the training of Marine Nationale officers, France’s diplomatic presence abroad, and the ability to operate helicopters in military missions.
Registered by the Historical Defense Service of France as helicopter carrier Jeanne d’Arc, in service between 1964 and 2010, the ship became one of the most recognized platforms of the French Navy in the post-World War II period.
Built at the Brest Arsenal, the ship was launched under the name La Résolue before receiving, in 1964, the designation Jeanne d’Arc and assuming the role that would mark its operational trajectory.

From this change, the vessel began to serve as a training ship for officers in training, while maintaining a real military configuration, capable of supporting missions of presence, transport, embarked aviation, and command.
With a long silhouette, aft flight deck, aircraft hangar, and superstructure typical of French naval engineering of the Cold War, the Jeanne d’Arc presented an unusual profile among training ships.
Its size also reinforced this difference, as its approximately 181 meters in length and displacement of over 12,000 tons at full load allowed for ocean crossings and long-duration missions.
Jeanne d’Arc was a training ship and military platform
In peacetime, the main mission of the Jeanne d’Arc was to train officers in a practical routine of navigation, command, naval diplomacy, and life on board, bringing technical learning closer to real sea experience.
During the so-called application campaign, young officers participated in trips to foreign ports, international exercises, and long crossings, in training that combined instruction, discipline, institutional relationships, and operational routine.
This didactic vocation, however, did not reduce the ship to an instructional platform without military utility, because its classification as a helicopter cruiser preserved its capacity for use in crisis scenarios.
If necessary, the Jeanne d’Arc could support anti-submarine warfare operations, transport, amphibious support, evacuation, humanitarian assistance, and military presence in strategic areas of interest to France.
The origin of the project helps explain this dual function, as the vessel emerged during a period when Paris sought to assert strategic autonomy under the leadership of Charles de Gaulle.
In that context, French defense included its own nuclear force, expeditionary capability, and naval means capable of operating far from Europe, which increased the value of a training platform with global reach.
Helicopters extended operational reach
The main differentiator of the Jeanne d’Arc was the embarked rotary-wing aviation, a resource that allowed the ship to carry out various missions without relying on fixed-wing aircraft.
Unlike classic aircraft carriers, it did not launch combat planes; still, it had aviation facilities far superior to those of a conventional cruiser and could adapt its air wing to the designated mission.
Throughout its career, the ship operated or could embark helicopters like Alouette III, Puma, Gazelle, Super Frelon, and Lynx, a variety that increased its utility in naval and expeditionary scenarios.
In the anti-submarine warfare configuration, the vessel could operate with WG 13 Lynx helicopters, while external missions allowed the use of French Army Puma and Gazelle, as well as naval aircraft and heavy models.
This combination gave flexibility to the ship, as the helicopters could perform transport, liaison, surveillance, support to landing forces, and anti-submarine search, while the hull offered oceanic autonomy and command structure.
Global presence marked the history of the Marine Nationale
Inside the ship, the training of officers went beyond naval technique and included leadership, discipline, international relations, operational routine, and administration of a large crew in a closed and hierarchical environment.
Over the years, the Jeanne d’Arc came to be simply called “La Jeanne,” a nickname that reflected the emotional bond built between the vessel and generations of French sailors.
For many officers, the campaign on board served as a rite of passage in their naval career; for foreign cities, the arrival of the ship represented a French diplomatic visit of strong symbolism.
During international stops, the vessel acted as a floating embassy of France, reinforcing political ties, supporting overseas French communities, and demonstrating the maintenance of a global naval presence.
Besides the diplomatic dimension, this presence had strategic value, as ships with this profile could support evacuations, humanitarian operations, and deterrence missions without mobilizing a complete naval air group.
Exocet missiles reinforced self-defense
The armament of the Jeanne d’Arc matched its hybrid nature, with cannons, short-range defense systems, and MM38 Exocet anti-ship missiles incorporated throughout its career.
Although these features enhanced its self-defense capability and employment in surface scenarios, the greatest value of the vessel came from the combination of helicopters, oceanic range, command, and officer training.
In anti-surface warfare missions, helicopters armed with anti-ship missiles could extend the attack range compared to navies without equivalent embarked aviation.
In the Brazilian case, aircraft carriers like the Minas Gerais and later the São Paulo were associated with the operation of embarked aircraft, while the Atlântico took on the role of a multipurpose aircraft carrier.
Last campaign ended 46 years of service
Throughout its career, the Jeanne d’Arc went through distinct phases of French military history, from the Cold War to the reorganization of expeditionary operations in the period after the fall of the Soviet Union.
Even with the evolution of amphibious ships and naval aviation, the vessel remained relevant due to its ability to combine training, international presence, and operational employment on a single platform.
In the 2000s, however, age began to weigh on the ship, whose systems belonged to another technological generation and required increasingly complex maintenance.
Meanwhile, the French Navy already had Mistral-class ships, more modern and suitable for amphibious, humanitarian, and command operations, as well as more aligned with contemporary expeditionary needs.
The last campaign of the Jeanne d’Arc took place in 2009-2010, when the ship carried out its final training and presence commission before returning to Brest in May 2010.
After the formal withdrawal from active service, the tradition was preserved by the Mission Jeanne d’Arc, conducted annually by an amphibious ship of the Mistral class accompanied by a frigate.
In 2025, for example, the Jeanne d’Arc mission involved the Mistral and the frigate Surcouf in a deployment through the North Atlantic and the Arctic, keeping alive the name associated with French naval training.
After decommissioning, the former helicopter carrier was prepared for dismantling, while symbolic parts were preserved for their historical and institutional value.
For Brest and the Marine Nationale, a vessel that had combined naval school, diplomacy, embarked aviation, and military capability on a single platform ceased to exist physically.
