The Zeppelin LZ 13 Hansa (or simply Hansa) was a German civilian rigid airship first flown in 1912. It was built for DELAG to carry passengers and post and flew the first international passenger flight, visiting Denmark and Sweden in September 1912. In 1913 it was hired to the German Navy as a training craft, and at the outbreak of World War I it was requisitioned by the German military who used it for bombing, reconnaissance, and finally as a training airship.
