The Brumaire-class submarines were built for the French Navy prior to World War I. There were sixteen vessels in this class, of the Laubeuf type.
All saw action during the First World War, with three boats lost.
The French Navy built 34 Laubeuf-type submarines between 1906 and 1911. These are usually described as two classes, of which the Brumaire class was one, the other being the Pluviôse class. (Another source treats the vessels as one group, divided by the yards that built them). The boats had two naming schemes; the earlier vessels were named after the months of the French Revolutionary calendar, and the later ones after French scientists. However, apart from the name ship of the class, only two were named after months; the remaining thirteen boats of the Brumaire class were named for scientists.
The Brumaire class were Laubeuf type submarines, following the Laubeuf standard design of double hull and dual propulsion systems (as were the Pluviôse class). The Brumaire boats had electric motors for underwater propulsion, and are usually listed as having diesel engines for surface propulsion, though in practice this was mixed. While most had diesels several of the earlier boats had steam engines. These had been preferred by Laubeuf in the early stages, though later Laubeuf type submarines, such as the Circé class, predecessors to the Pluviôse and Brumaire classes, had used diesel engines, and some of the later Pluviôse boats had diesels.
The Brumaire class were ordered in the 1906 programme and the first vessels were laid down the same year. However construction proceeded more slowly than the Pluviôse boats, and the first of the class, Brumaire was not launched until four years later, priority being given to the Pluviôse boats. The boats were built at three of the French Navy’s dockyards, at the Arsenals of Cherbourg, Rochefort and Toulon. The first of the class, Brumaire, was launched in April 1911, and the last, Franklin in March 1913.
