The Convair B-58A was a Mach 2 nuclear bomber used by the
USAF in the 1960s in two Bomber Wings. Initially, it carried a single warload in combined fuel/weapon MB-1C
pod. Out of the 103 production airframes, 17 were ordered as RB-58A strategic reconnaissance bomber which were
scheduled to be equipped with a specific MC-1A photo-reconnaissance pod. The cancellation of th MC-1A programme
lead these airframes to be converted to standard B-58A bombers. However, as from 1964 the 43rd BW operated a
modified MB-1C pod turned into a low altitude photo-reconnaissance suite, the LA-331, with 48 of the 43rd BW airframes
being modified to operate them.
The weight breakdown of the strike pod could be seen as
||4,172 US gal
Some time during its operational life, the B-58A were donned
with a two compartments pod carrying less fuel, and with underwing pylons to carry a total of four Mk43 nuclear bombs to
supplement the single weapon carried internally. The carrying and release of conventional weapons from these
pylons was tested and cleared but the idea of using the type for low altitude conventional strike was abandoned.
