The Floréal class is a type of light "surveillance frigates" 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.

French Republican calendar
The French Republican calendar, also commonly called the French Revolutionary calendar, was a calendar created and implemented during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871, and meant to replace the Gregorian calendar.
