The Zeppelin LZ 13 Hansa (or simply Hansa) was a German civilian rigid airship first flown in 1912 with a volume of 18,700 cubic metres. It was first operated by DELAG to carry passengers and post and flew the first scheduled international passenger flights (starting with the visit to Denmark and Sweden in September 1912). At the outbreak of World War I, the German military requisitioned it for use in attack flights, reconnaissance, and finally as a training airship.
