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.

German CL class aircraft were light two-seaters used as escort fighters and ground attack aircraft. Developed from the Halberstadt CL.II, the nimble CL.IV was manoeuvrable and easy to fly. It saw action in the final battles of WWI in 1918.
