and France. After being enlarged in summer 1915, several more missions were carried out before S.L.2 was stranded at Luckenwalde on 10 January 1916 after running out of fuel and decommissioned. The S.L.2 demonstrated the Schütte-Lanz wood girder's advantage in compression as opposed to tension allowed the Schütte-Lanz type of airship to be technically superior until a certain size had been reached.

The highlight of S.L.3's career was its attack on the British submarine E4 on 24 September 1915. The structure of the ship degraded because of atmospheric exposure and the ship was stranded near Riga on 1 May 1916. First Flight: 4 February 1915 Length: Diameter: Gas Capacity: Performance: Payload: Engines: 4x Maybach C-X 6-cyl in-line engines: total S.L.4 (Type 'c') Naval airship based at Seddin. S.L.4 flew 21 reconnaissance missions and two bombing raids against enemy harbours on the Eastern front. It was destroyed on 14 December 1915 after its hangar collapsed due to snow accumulation on the roof. First Flight: 2 May 1915 Length: Diameter: Gas Capacity: Performance: Payload: Engines:4x Maybach C-X 6-cyl in-line engines: total S.L.5 (Type 'c') S.L.5 was an army airship, based at Darmstadt. The structure was damaged during the first flight, but repaired after several months work. During its second flight the ship was forced down by bad weather at Gießen and stricken from service on 5 July 1915 First Flight: 4 February 1915 Length: Diameter: Gas Capacity: Performance: Payload: Engines: 4x Maybach C-X 6-cyl in-line engines: total S.L.6 (Type 'd') Naval airship based at Seddin. Flew six reconnaissance missions, but exploded due to unknown causes with the loss of all hands while taking off on 10 November 1915.
