The Halberstadt CL.IV was one of the best ground attack aircraft of World War I. It performed well in combat as a low-level attack airplane, relying on its good maneuverability to avoid ground fire. This WWI combat veteran was one of three restored by Deutsches Technikmuseum in Berlin, being completed in June 1991 and is now on display at the Smithsonian's Udvar Hazy Center.
