Sedunn and Ryccia were the first countries to develop and test nuclear weapons following the completion of the joint nuclear weapons programme codenamed Case Yellow Fox (CYF) in 1957. However, Sedunn had been researching nuclear weapons since at least 1941 not long after the discovery of nuclear fission. The programme codenamed Nilet Ruetunn ("Thoughtful Greeting") had a slow start and faced several difficulties as well as budget restraints. In 1949 CYF merged Sedunn's and Ryccia's separate programmes aiming for an expedited deployment against the Imperialists of the Great War as a means to force a swifter end to the conflict. While both nations had access to significant deposits of fissile material domestically, the programme initially had process issues failing to enrich relevant amounts of fissile material. The programme was also delayed by a significant espionage threat that forced the development of several "false" separate clones of the programme. The distance between Sedunn and Ryccia proved a significant challenge as well, especially early during the Great War when the Allies did not yet enjoy supremacy in the South Pacific Ocean.
The Great War ended before the first CYF nuclear bomb had been manufactured; it is estimated that it would have been ready for a first test in March or April 1956, alternatively early in 1957. Upon success, troop concentrations and/or army command centres to the west of Karnetgrad were likely the designated target for the very first atomic raid. It was decided to postpone the first test as there no longer was any urgency and it was estimated that it would be useful to already have access to a small arsenal once rivals learned of the new weapon.
