French Navy Daphne class
Prior to WW-II the French Marine National had established a clear distinction between long-range (`1st class`) submarine of 1,500 tons, and medium-range (`2ed class`) submarine of about half that size. This policy was to continue in the postwar period. The Narval class which was closely modeled on the German type XXI, became thestandard 1st class type, and in 1952 the General Staff requested the design of a 2ed class counterpart, which was to become the Daphne. Staff requirements included low noise, good maneuverability, a small crew, and ease of maintenance-by employing extensive automation and adopting unit replacement techniques to minimize onboard maintenance.
