 In April 1941, the possibility of Great Britain falling to Nazi Germany seemed very real, and so the United States Army Air Corps unveiled a competition for a long-range bomber with intercontinental range (10,000 miles), making it capable of conducting air-strikes on Nazi-occupied Europe from US bases.Douglas stated that it did not wish to produce an 'out-and-out 10,000-mile (16,090 km) airplane project', instead proposing the Model 423 with a range of 6,000 miles (9,654 km).The Douglas Model 423 was eventually rejected in favor of the Consolidated Model 36, which became the Convair B-36 Peacemaker.
