When the B-58 Hustler bomber entered service in 1958 it was a very futuristic looking delta wing bomber, creating a lot of sensation. Intended as a successor of the B-47 Stratojet it could reach twice the speed of sound.However, problems occurred during the development process and costs risings went so out of control that the whole project was almost cancelled a few times. Strategic Air Command was initially against ordering the B-58 for service, not only because of its complexity but also since they saw no advantage of a Mach 2 bomber over other types. Despite this the B-58 entered service at S.A.C. in 1960. It would have a relatively short operational career.
