The Soviet Union detonated its first atomic bomb on August 29, 1949. This test, codenamed "First Lightning" or "Joe 1," marked the USSR's entry into the nuclear arms race, following the United States' atomic bombings of Hiroshima and Nagasaki in 1945. The successful detonation significantly shifted the geopolitical landscape during the Cold War.
