Test chronology

Ace was the first detonation of a nuclear weapon conducted by the Fallish Federation and Crowned Republic of Mascylla jointly as a result of the efforts of Operation Whitehorse on the island of Jürsand at 11:00 a.m. on March 5, 1950, as part of one of the Melasian Crisis's arms race between Mascylla and Cuthland. The testing site was the desolate and uninhabited Jürsand island about 110 kilometres (68 miles) east of Ankstedt, situated in what was then the MGR Jürsand-Kappe Marine Testing and Proving Territory. For the purposes of the test, the Jürsand Proximity Site and three other buildings were built in the vicinity of the blast zone to observe effects of the detonation on the structures and to use them as laboratories for nuclear weapon components.

The test was of an implosion fission reaction uranium device, which was informally nicknamed Dawn. Ace was of a similar design to the Iron Lad bomb later deployed and detonated over X, Cuthland on X X 1944, ending the Melasian Crisis at large. The complexity of the design required the efforts of the entire Fallish Armed Forces and Reichswehr, and concerns about whether it would work led to a decision to conduct the nuclear test afterall. However, the success of the test had foremost priority as Cuthland was amid the development of new technologies in the wake of rapidly worsening tensions with Mascylla during the Melasian Crisis, and therefore Mascylla's security was regarded highly endangered; the collaboration between both countries contributed to the later cooperation in the Berean Defence Treaty Association and the Template:Country data nuclear weapons sharing of the stockpile. The project was overseen by Fallish Prime Minister X and Mascyllary Prime Minister Ernest Rähner, and the test was principalised and directed by X and Gerhard Wayner. The nuclear weapon was the culmination of crucial scientific reconaissance and intelligence brought about by the efforts of Operation Whitehorse.

Ace released the explosion yield of about 27 kilotons of TNT, exceeding the predicted 22 kilotons, due to unforeseen additional reactions and highly enriched uranium being used. At the time of its detonation, it was the largest artificially generated explosion in history.
