    Heinkel He 277 (Amerika Bomber) Heavy Bomber Project

    Like other multi-engine heavy bomber projects of the Germans during World War 2, little became of the Heinkel He 277 design.

    There were many German aviation concerns lending their talents to the war effort of World War 2 (1939-1945) but only a few stood above the others - Heinkel, Messerschmitt, Focke-Wulf being some of the more notable ones. While Heinkel's contribution is largely through its He 111 medium bomber series, it also tried its hand at a larger, more advanced multi-engined platform in the ultimately-failed He 177 "Greif" ("Griffon"). A unique compound engine arrangement was featured which coupled a pair of Daimler-Benz DB605 inline engines (as the DB610) but these proved prone to catching fire and several prototypes were lost in development. Structural issues only served to limit the type in production as fewer than 1,000 examples were seen by war's end - manufacture was actually ended earlier in 1944.

    Back in April of 1942, the RLM initiated the "Amerika Bomber" program which called for a new long-range bomber featuring inherent endurance to bomb targets along the American East Coast following the United States' entry into World War 2 (December 1941). The range in question was about 3,600 miles and various companies threw their hat into the ring, various designs being contemplated which ranged from the conventional to the more advanced/bizarre. One final quality of the large aircraft would be provision to deliver an atomic bomb under development by German scientists before the end of the war.

    The companies called to further their more conventionally-minded/conventionally-powered designs became Focke-Wulf, Heinkel, Junkers and Messerschmitt. For Focke-Wulf this became the Fw 300 and Ta 400 entries and Heinkel followed with their He 277 based on the aforementioned He 177. Junkers worked on their Ju 390 concept and Messerschmitt poured its resources into the Me 264. No one offering made it into operational service and eight prototypes (five from Junkers and three from Messerschmitt) was all there was to show for the late-war effort.
