Heavy Bomber
Heavy bombers are bomber Fixed-wing aircraft, aircraft capable of delivering the largest payload of air-to-ground weaponry (usually Aerial bomb, bombs) and longest range (aeronautics), range (takeoff to landing) of their era.

In the second half of the 20th century, heavy bombers were largely superseded by strategic bombers, which were often even larger in size, had much longer ranges and were capable of delivering nuclear bombs. Because of advances in Aerospace engineering, aircraft design and engineering — especially in Aircraft engine, powerplants and aerodynamics — the size of payloads carried by heavy bombers has increased at rates greater than increases in the size of their airframes. The largest bombers of World War I, the ''Riesenflugzeuge'' of Germany, could carry a payload of up to of bombs; by the latter half of World ...

The B-17 was also employed in transport, anti-submarine warfare, and search and rescue roles.

Still, the Air Corps ordered 13 more B-17s for further evaluation, which were introduced into service in 1938. The B-17 evolved through numerous Boeing B-17 Flyin ...
