The LZ 121 was a civilian airship from the Weimar Republic, a Y-Class zeppelin with a total length of 130.8 metres (429 ft 2 in).

The ship could reach a top speed of 130 km/h, with four Maybach Mb IVa, 245 hp 6-cylinder inline engines driving three propellers.

The older sister ship LZ 120 Bodensee did run a regular passenger service between Friedrichshafen and Berlin in late 1919.

The Commission Chairman General E. A. Masterman decided on 9 August 1920 that the two airships be given to France and Italy as war reparations.

[4] LZ 121 was put under the command of the French airline Société Anonyme de Navigation Aérienne (Sana), where it was renamed Méditerranée and operated as a Zeppelin air transport between southern France and Algeria.
