America has seen some supersonic strategic bombers serve. Notable among these is the FB-111A Switchblade and the B-1B Lancer. But one bomber blazed the trail for these speedsters with a pretty huge payload.
The Convair B-58 Hustler was the first operational supersonic strategic bomber in American service. Aviation historian Joe Baugher noted that Strategic Air Command was looking for a high-performance bomber.

The B-58 made its first flight in 1956, but didn't enter service with the Strategic Air Command until 1960, due to a number of hiccups, and wasn't ready to stand alert until 1962. However, when the bomber entered service with the 43rd Bomb Wing, it was soon proving it had a lot of capability.
However, in 1961 and 1962, even as it dealt with the teething problems, it set numerous aeronautical records. The plane had a top speed of Mach 2.2 at high altitude, a maximum range of 4100 nautical miles, could carry five nuclear bombs (it never had a conventional weapons capability), and reached an altitude of 85,360 feet.
It also had a M61 Vulcan cannon in the tail with 1,200 rounds of awesome.

Ultimately, the B-58 was retired, and replaced by the FB-111A. The FB-111A not only was supersonic, but it was able to operate at low altitudes and carry conventional bombs – addressing the B-58's two shortcomings.
Most B-58s went to Davis-Monthan Air Force Base where they entered the boneyard and were eventually scrapped.
