The second nation to develop an atomic bomb was the Soviet Union. They successfully tested their first atomic bomb, known as "First Lightning," on August 29, 1949, following the United States, which conducted its first successful test in 1945. The Soviet atomic bomb program was accelerated by espionage efforts that provided them with crucial information from the American Manhattan Project.
