Chantiers de l'Atlantique in the context of "French frigate Nivôse"

The Floréal class is a type of light "surveillance frigates" (French: frégate de surveillance) designed for the needs of the French Navy in low-threat environments ordered in 1989. The ships are named after months of the Republican Calendar. They use construction standards of commercial ships. The frigates were built between 1990 and 1993 by the Chantiers de l'Atlantique at Saint-Nazaire, France. The six French ships of the class, Floréal, Prairial, Nivôse, Ventôse, Vendémiaire and Germinal, remain in active service.

The ships' main armament was two Exocet MM38 surface-to-surface missiles and a 100 mm (4 in) CADAM turret, but in 2014, the Exocets were removed at the end of their life cycle. The vessels have a maximum speed of 20 knots (37 km/h; 23 mph) and can carry 24 marines. The vessels are used mainly to patrol the French overseas departments and regions in the Pacific, Indian Ocean and Caribbean regions, but have served in both military and humanitarian operations in the Persian Gulf and the Gulf of Guinea.

Alstom SA (French: [alstɔm]) is a French multinational rail transport systems manufacturer. It is active in the fields of passenger transportation, rail services, signalling, and locomotives, producing high-speed, suburban, regional and urban trains along with trams.

The company and its name (originally spelled Alsthom) were formed by a merger between the electric engineering division of Société Alsacienne de Constructions Mécaniques (Als) and Compagnie Française Thomson-Houston (thom) in 1928. Significant acquisitions later included the Constructions Électriques de France (1932), shipbuilder Chantiers de l'Atlantique (1976), and parts of ACEC (late 1980s).

Saint-Nazaire (French: [sɛ̃ nazɛːʁ] ; Breton: Sant-Nazer/Señ Neñseir; Gallo: Saint-Nazère/Saint-Nazaer) is a port town and commune in the Loire-Atlantique department in western France, in traditional Brittany.

The town has a major harbour on the right bank of the Loire estuary, near the Atlantic Ocean. The town is at the south of the second-largest swamp in France, called "la Brière". Given its location, Saint-Nazaire has a long tradition of fishing and shipbuilding. The Chantiers de l'Atlantique, one of the largest shipyards in the world, constructed notable ocean liners such as SS Normandie, SS France, RMS Queen Mary 2 and the cruise ship MS Symphony of the Seas, the largest passenger ship in the world until 2022.

Floréal is the lead ship of the Floréal-class frigates (French: frégates de surveillance) of the French Navy. Floréal is the first French vessel named after the eighth month of the Republican Calendar. The ship was constructed by Chantiers de l'Atlantique at Saint-Nazaire, France, in 1992 and entered service in 1993. Floréal is stationed at Réunion in the Indian Ocean for patrol duties.

Prairial is a Floréal-class frigate (French: frégate de surveillance) of the French Navy. She is the second ship of the class, and the second French warship named after the ninth month of the Republican Calendar. The ship was constructed by Chantiers de l'Atlantique at Saint-Nazaire, France, in 1992 and entered service in 1993. Prairial is stationed in the French Pacific territories for patrol duties.

Ventôse is a Floréal-class frigate (French: frégate de surveillance) of the French Navy. The frigate is the fourth ship of its class, and the first French vessel named after Ventôse, the sixth month of the Republican Calendar, the month of wind. The ship was constructed by Chantiers de l'Atlantique at Saint-Nazaire, France, in 1991–1992 and entered service in 1993. Ventôse is stationed in the French Caribbean Sea territories for patrol duties.

RMS Queen Mary 2 (QM2) is a British ocean liner. She has served as the flagship of the Cunard Line since April 2004, and as of 2025, is the only active, purpose-built ocean liner still in service. Queen Mary 2 sails regular transatlantic crossings between Southampton and New York City, in addition to short cruises and an annual world voyage.

She was designed by a team of British naval architects led by Stephen Payne, and was constructed in France by Chantiers de l'Atlantique. At the time of her construction, Queen Mary 2 was the longest, at 1,131.99 ft (345.03 m), and largest, with a gross tonnage of 148,528 GT, passenger ship ever built. She no longer holds these records after the construction of Royal Caribbean International's 154,407 GT Freedom of the Seas (a cruise ship) in April 2006, but remains the largest ocean liner ever built.
