French submarine Narval (“Narwhal”) was a pioneering vessel of the French Navy, designed by Maxime Laubeuf and built at the end of the 19th century. She was designed in response to a competition set by the French Admiralty and had several revolutionary features which set the pattern for submarines for the next 50 years.

The Naïade-class submarines, sometimes referred to as the Perle class were a group of submarines built for the French Navy at the beginning of the 20th century. There were twenty vessels in this class, which was designed by Gaston Romazotti. The class introduced internal combustion engines into French submarine design. They remained in service until just prior to the outbreak of the First World War.
The Farfadet class consisted of four submarines built for the French Navy at the beginning of the 20th century designed by Gabriel Maugas. Two boats were lost in diving accidents. All were disposed of prior to the outbreak of the First World War.

It was sunk on 28 February 1943 10 miles off Murro di Porco, Sicily by Allied aircraft.
The Aigrette-class submarines were a class of two submarines built for the French Navy between 1903 and 1905. They were essentially experimental submarines, and although in service during World War I, saw no action. The class was designed by Maxime Laubeuf and used Drzewiecki drop collar launchers and external cradles to launch torpedoes.
Aigrette was the lead boat of the Aigrette-class submarines built for the French Navy between 1902 and 1905. Laid down in May 1902, she was launched in February 1904 and commissioned in 1908. She was essentially an experimental submarine, and although in service during World War I, saw no action. The class was designed by Maxime Laubeuf and used Drzewiecki drop collar launchers and external cradles to launch torpedoes.
The French submarine Laplace (Q111) was a Lagrange-class submarine built for the French Navy built between 1913 and 1919. It was laid down in the Arsenal de Rochefort shipyards and launched on 12 August 1919. Laplace was completed in 1921 and served in the French Marine Nationale until 1935.
The French submarine Lagrange (Q112) was a Lagrange-class submarine built for the French Navy built between 1913 and 1918. It was laid down in the Arsenal de Toulon shipyards and launched on August 12, 1919. Lagrange was completed in 1918 but saw no action during World War I and served in the French Marine Nationale until 1935.
The French submarine Regnault (Q113) was a Lagrange-class submarine built for the French Navy built between 1913 and 1924. It was laid down in the Arsenal de Toulon shipyards and launched on June 25, 1924. Regnault was completed in 1924 and served in the French Marine Nationale until 1937.
The French submarine Romazotti (Q114) was a Lagrange-class submarine built for the French Navy built between 1914 and 1918, during World War I. It was laid down in the Arsenal de Toulon shipyards and launched on March 31, 1918. Romazotti was completed in 1918 and served in the French Marine Nationale until 1937.
The Armide-class submarines were a class of three diesel-electric submarines built for the Greek and Japanese Navies before and during World War I. They were built in the Schneider-Creusot shipyards 1913 to 1918, but were seized during the war by the French government before they could be sold. The Armide class ships operated in the Mediterranean during the course of World War I and were stricken from the Navy list between 1928 and 1935.
Armide was a submarine ordered by the Japanese Navy from the Schneider-Creusot shipyard before World War I but was requisitioned by the French government before it was launched. Armide operated in the Mediterranean during the course of World War I and was stricken from the Navy list in July 1932.
The French submarine Antigone was an Armide-class diesel-electric attack submarine originally ordered by Greece. It was built in the Schneider-Creusot shipyards between 1912 and 1917, but was requisitioned on 30 May 1917 by the French Government before it was delivered. Antigone operated in the Mediterranean during the course of World War I and was stricken from the Navy list in August 1935.
X was a steel single hull submarine built for the French Navy between 1904 and 1905. She was launched in November 1904 and commissioned in 1905. Gaston Romazzotti modified the design of Farfadet to create an experimental submarine which was the first with twin shafts.
The French submarine Z was an experimental submarine built for the French Navy between 1902 and 1905. It was laid down in April 1902, launched in March 1904 and completed in 1905. Designed by Gabriel Maugas, Z was essentially an experimental submarine and it was the first French submarine to be commissioned with a diesel engine although Aigrette was the first to be launched.
The French submarine Y was a single-hull experimental submarine designed by Louis-Émile Bertin for the French Navy. She was launched in July 1905 but was never commissioned and remained in experimental status. A planned refit, which included adding an electric motor for underwater propulsion in 1907 was cancelled. Y was disarmed and stricken on 1 March 1909.
The French submarine Argonaute was an experimental attack submarine built for the French Navy between 1903 and 1911. Initially named Omega, Argonaute was laid down in January 1903, launched in November 1905 and commissioned in 1911. She was essentially an experimental submarine, and although in service during World War I, saw no action. Argonaute was decommissioned in 1919.
The Guêpe-class submarines were a planned class of submarines to be built for the French Navy ordered in 1904. Ten of the class were projected but only two were laid down before the whole project was cancelled. Construction of the two vessels that were laid down began in 1906, but it was stopped in 1908 before they could be completed.
