The United States has the expertise necessary to operate supersonic planes, and as with any expertise, it had to begin with a pioneering effort.
It was the Convair B-58 Hustler that earned the distinction of becoming the first ever supersonic jet bomber in the United States.
On Veteran's Day in 1956, the B-58 Hustler made its first flight, and on March 15, 1960.
It was formally accepted into service with the United States Air Force for operational purposes.
She was constructed by the now-defunct Convair Division of General Dynamics, which also produced the F-106 Delta Dart interceptor.
