The RDS-1 (), also known as First Lightning (), was the first nuclear weapons test that was conducted by the Soviet Union. It was detonated on 29 August 1949 at 7:00 a.m. Kazakhstan Time (decree time) (UTC+06:00), at the Semipalatinsk Test Site in the Kazakh Soviet Socialist Republic, and yielded 22 kilotons of TNT.
It was roughly based on the American design, Fat Man, and the United States assigned it the code-name Joe-1, in reference to Joseph Stalin. RDS-1 also refers to the model of nuclear gravity bomb put into weapons production, with 29 bombs stockpiled by 1951.
