The Amerikabomber (English: America bomber) project was an initiative of the German Reichsluftfahrtministerium to obtain a long-range strategic bomber for the Luftwaffe that would be capable of striking the United States from Germany, a round-trip distance of about 11,600 km (7,200 mi). The concept was raised as early as 1938, but advanced, cogent plans for such a long-range strategic bomber design did not begin to appear in Reichsmarschall Hermann Göring's offices until early 1942. Various proposals were put forward, including using the Amerikabomber to deliver proposed German nuclear weapons[citation needed]; these plans were all eventually abandoned as too expensive, too reliant on rapidly-diminishing materiel and production capacity, and/or technically unfeasible.
