The Junkers J11 was an all-metal two-seat floatplane fighter prototype competing with the Dornier Cs.I and the Brandenburg monoplanes. Powered by a 200 hp Benz Bz.IV, it had a maximum speed of 180 kmh, faster than the Brandenburg W29. Sturdy and durable, it would have been welcomed by maintenance crews. Both Dornier and Junkers were building all-metal monoplanes by the end of the war. There were no Allied all-metal warplanes; Germany clearly led the field in structural design.
The all-metal Junkers CLS.I was a floatplane development of the CL.I two-seat fighter. The CL.I was produced for the army and used postwar. The CLS.I was powered by a 200 hp Benz Bz.IV engine.The CLS.I had a top speed of 180 km/h, which was somewhat faster than the W29. The corrugated metal skin was characteristic of early Junkers designs. -

Marine #7501 was a floatplane adaption of the all-metal Junkers CL.I two-seat fighter. The CL.I landplane had no fixed fin, but one was required on the CLS.I due to the destabilizing effect of the floats. The CLS.I tail surfaces underwent extensive modifications to achieve good flying characteristics, but the type arrived too late for wartime service.

The Junkers J11 competed with the Zeppelin Cs.I. It used corrugated duralumin panels and was not the more advanced stressed skin structure of the Zeppelin Cs.I.

Junkers J11 (CLS1)
The J11 was a floatplane version of the J10 for use as a two-seat, maritime patrol aircraft for the German Navy. It began with the modification of two J10s (c/ns 7501 and 7503) of corrugated Duralumin construction. Their rear fuselages were altered, their wing area was increased, a triangular tailfin was added and rudimentary, braced floats were fitted. The J11 was armed with a machine gun on either side of the cockpit and was powered by a Benz Bz IIIa 180hp engine. Only three were built, the first (7501/18) making its initial flight on 23 October 1918 piloted by Navy pilot Richard Thiedemann. The war’s end brought about a closure to the programme.
