The Horten H.XVIII was a proposed German World War II intercontinental bomber, designed by the Horten brothers. The unbuilt H.XVIII represented, in many respects, a scaled-up version of the Horten Ho 229, a prototype jet fighter. The H.XVIII was one of many proposed designs for an Amerikabomber, and would have carried sufficient fuel for transatlantic flights. The XVIIIA variant, with its wood structure, buried engines in the fuselage, flying wing design and carbon-based glue component, would have been, in theory, the first stealth bomber in history.
The A model of the H.XVIII was a long, smooth blended wing body. Its six turbojet engines were buried deep in the wing and the exhausts centered on the trailing end. Resembling the Horten Ho 229 flying wing fighter there were many odd features that distinguished this aircraft; the jettisonable landing gear and the wing made of wood and carbon based glue, are but two. The aircraft was first proposed for the Amerika Bomber project and was personally reviewed by Hermann Göring: after review, the Horten brothers (with deep dissatisfaction) were forced to share design and construction of the aircraft with Junkers and Messerschmitt engineers, who wanted to add a single rudder fin as well as suggesting underwing pods to house the engines and landing gear.
