The Halberstadt CL.iV was one of the most effective ground attack aircraft of World War One and around 700 were built. Its manoeuvrability allowed it to avoid ground fire and it was also used as an escort fighter. On bright moonlit nights it was even used as a night fighter. This is one of four surviving examples and was built by Luft-Fahrzeug-Gesellschaft (L.F.G.), usually known as Roland. It was one of six aircraft of the type bought by Paul Strähle, a former Jasta 18 fighter pilot, in 1919. He intended to use them for a passenger transport service and at least three were flown with the last finally being grounded in 1938. In 1982, Strähle sold this last aircraft together with all the spare fuselages and parts. The entire collection was traded with the USAF Museum for six T-28 Trojans in 1984 and this fuselage was then donated to the Smithsonian Institute. Three complete aircraft were assembled from the collection of parts and were then restored by Museum fur Verkehr and Technik (MVT) in Germany. MVT later became the Berlin Technikmuseum and they retained one of the restored aircraft for display while the other two were returned to the United States. One is on display in the National Museum of the United States Air Force in Dayton, Ohio, while this is the third, Roland built, example. Seen on display in the Steven F. Udvar Hazy Center as part of the National Air and Space Museum. Washington Dulles International Airport, Chantilly, Virginia
