Hannoversche Waggonfabrik A.G. (Hannover) is best known for their CL ground-attack aircraft. In 1915 they began building planes under license, including the Aviatik C.I, Rumpler C.Ia, and Halberstadt D.II. With the specification of the CL-class escort planes, Hannover began building planes of their own.
