History
The Halberstadt CL.II series of two-seat close-support biplanes was introduced during 1917, and the type became the standard German type for the duration of the war, supplanted but never replaced by the later CL.IV and Hannover C1 biplanes. Robust and efficient in construction, and powered by the 180 hp. Mercedes D.IIIau water-cooled engine, the type was used to support ground troops – attacking, strafing, and bombing enemy positions, and causing considerable problems in Allied operations. In addition to ground support, the type often encountered Allied fighters, and crews often held their own against the more nimble Allied single-seaters. Postwar, surviving aircraft were flown into the 1920s, and the only surviving example, which was originally displayed in a Berlin aviation museum, is currently in Poland awaiting restoration. Detail photos of this aircraft are included in this publication.
