The Convair B-58 Hustler

https://en.wikipedia.org/wiki/Convair_B-58_Hustler

The Convair B-58 Hustler was the first operational supersonic jet bomber capable
of Mach 2 flight. The aircraft was designed by Convair engineer Robert H. Widmer
and developed for the United States Air Force for service in the Strategic Air
Command (SAC) during the 1960s. It used a delta wing, which was also employed by
Convair fighters such as the F-102, with four General Electric J79 engines in
pods under the wing. It carried five nuclear weapons; four on pylons under the
wings, and one nuclear weapon and fuel in a combination bomb/fuel pod under the
fuselage, rather than in an internal bomb bay.

Replacing the Boeing B-47 Stratojet medium bomber, it was originally intended to
fly at high altitudes and supersonic speeds to avoid Soviet fighters. The B-58
received a great deal of notoriety due to its sonic boom, which was often heard
by the public as it passed overhead in supersonic flight.

The introduction of highly accurate Soviet surface-to-air missiles forced the
B-58 into a low-level penetration role that severely limited its range and
strategic value, and it was never employed to deliver conventional bombs. This
led to a brief operational career between 1960 and 1970 when the B-58 was
succeeded by the smaller, swing-wing FB-111A

The B-58 crews were chosen from other strategic bomber squadrons. Due to some
characteristics of delta-winged aircraft, new pilots used the Convair F-102
Delta Dagger as a conversion trainer, before moving to the TB-58A trainer.[24]
The B-58 was difficult to fly and its three-man crews were constantly busy, but
its performance was exceptional. A lightly loaded Hustler would climb at nearly
46,000 ft/min (235 m/s).[25] In addition to its much smaller weapons load and
more limited range than the Boeing B-52 Stratofortress, the B-58 had also been
extremely expensive to acquire.
