Chantiers de l'Atlantique

Chantiers de l'Atlantique is a major French shipbuilding company based at the historic Penhoët shipyard in Saint-Nazaire. Renowned globally for constructing some of the world's largest and most sophisticated vessels, its portfolio includes ocean liners, cruise ships, LNG carriers, and naval units for the French Navy. The yard's expertise in complex maritime engineering has made it a strategic national asset, with its ownership transitioning from private industrial groups back to the French State in recent years.

History

The modern entity was formed in 1955 through the merger of Chantiers de la Loire and Chantiers de Penhoët, consolidating shipbuilding activities in Saint-Nazaire that date to the 19th century. It gained fame in the 1960s by constructing the legendary French Line flagship SS France (1960), one of the last great transatlantic liners. Following a period of state control under Alstom beginning in 2006, the yard was acquired by the South Korean conglomerate STX Corporation in 2008, becoming part of STX Europe. Facing financial difficulties, control was reacquired by the French State in 2018 to preserve this critical industrial capability, with the Italian shipbuilding group Fincantieri initially set to become a major shareholder before negotiations shifted.

Notable ships built

The shipyard's legacy is defined by iconic passenger ships, beginning with the SS Normandie in 1935, which won the Blue Riband. In the modern era, it built the Queen Mary 2 in 2004 for Cunard Line, the largest ocean liner ever constructed. It has since dominated the cruise ship market, delivering numerous record-breaking vessels for Royal Caribbean International, including the Oasis-class cruise ship series like MS Symphony of the Seas and the new Icon-class cruise ship, Icon of the Seas, the world's largest cruise ship. Other significant builds include the MSC Cruises MSC World Europa and naval vessels such as the French aircraft carrier Charles de Gaulle (R91).

Facilities and operations

The primary facility is located at the Penhoët site in the Port of Saint-Nazaire, featuring one of the largest dry docks in the world, the Forme Joubert. This immense basin allows for the construction and outfitting of the largest cruise ships and LNG carriers. The yard integrates advanced welding techniques, modular construction, and extensive outfitting halls. Its operations also encompass the design and construction of sophisticated offshore energy structures and it engages in major retrofitting and repair projects, serving clients like the United States Navy and various commercial fleets.

Corporate structure and ownership

Since 2018, the majority shareholder has been the French State, represented by the Agence des participations de l'État. A planned sale of a significant stake to Fincantieri was blocked by the French government on strategic grounds in 2022. Current shareholding is split between the French State, Naval Group, and employee holdings. The company operates as a key industrial pillar within France's broader maritime and defense ecosystem, collaborating closely with Naval Group on military projects and with ENGIE on energy transition technologies like hydrogen-powered ships.
