On August 29, 1949, the Soviet Union detonated a plutonium-core nuclear weapon on the steppes of Kazakhstan. The test was secret. Five days later (on September 3), an American B-29 weather plane, on its daily flight between Japan and Alaska to expose radioactive-sensitive filter papers to the air, recorded higher-than-usual levels of radioactivity. This in turn triggered additional probes. By September 19, a group of top-level nuclear scientists had concluded that the detected particles were undoubtedly the traces of an atomic bomb explosion, later dubbed “Joe-1”. On September 23, the news of the Soviet test was announced by President Truman.
