Orange Herald
Two versions were designed - an "Orange Herald Large" with an overall diameter of 39 inches (1.0 m), and an "Orange Herald Small" with overall diameter of 30 inches (0.75 m). The difference between the two was in the size of the high explosives, the fissile cores were similar. Orange Herald Small was intended as warhead for a ballistic missile. Orange Herald Large was designed as device which would have the most certainty to give a yield in the megaton range. However, due to its size it was not suited as warhead for the ballistic missile and was more of an insurance which could be used if other devices failed to achieve the desired yield.
