The French submarine Morse was a Requin-class submarine built for the French Navy in the mid-1920s. Laid down in February 1923, it was launched in May 1925 and commissioned in February 1928. On 16 June 1940, Morse, under the command of Jean Georges Charles Paris, struck a mine and sank in the same minefield off the Kerkennah Islands that sank her sister ship Narval six months later.
