The French submarine "Narval" was a "Requin"-class submarine built for the French Navy in the mid-1920s. Laid down in March 1923, it was launched in May 1925 and commissioned in July 1926. It joined the Free French naval forces at Malta at the time of the French surrender during World War II. On or around 15 December 1940, "Narval" sank after striking a mine in the same minefield off the Kerkennah Islands that sank her sister ship "Morse" six months prior.
