noun

su·​per·​bomb·​er ˌsü-pər-ˈbä-mər 

plural superbombers

: a bomber (see bomber sense 1) that has a much greater payload, range, or maximum speed than a typical bomber

So pressing was the need for a long-range superbomber to attack Japan, the U.S. Army Air Forces had taken the unheard-of step of ordering 250 B-29s while the airplane was still only a plywood mock-up in Seattle.
