Schütte-Lanz (SL) is the name of a series of rigid airships designed and built by the Luftschiffbau Schütte-Lanz company from 1909 until the last LS22 was delivered in 1917. One research and four passenger airships were planned for post-war use but were never built. The Schütte-Lanz company was an early strong competitor of the more famous airships built by Ferdinand von Zeppelin.
