Junkers CLS.I

In 1918 three examples of the Junkers CLS.I were built, a floatplane version of the Junkers CL.I. The type did not go into production. It differed little from the CL.I except for the addition of a fin, and the tail surfaces never were quite worked out. The company designation was the J.11.

With longer wings than the CL.I, the CLS.I was over heavier, which resulted in a corresponding drop in performance. It was only postwar when it was given a 300hp Hispano engine that it reached its potential in the Junkers A-20.
