How did the Soviets first develop their nuclear weapons program?
On December 25, 1946, the Soviets created their first chain reaction in a graphite structure similar to Chicago Pile-1. The Soviets successfully tested their first nuclear device, called RDS-1 or “First Lightning” (codenamed “Joe-1” by the United States), at Semipalatinsk on August 29, 1949.
Who developed nuclear weapons?
Robert Oppenheimer
Robert Oppenheimer, “father of the atomic bomb.” On July 16, 1945, in a remote desert location near Alamogordo, New Mexico, the first atomic bomb was successfully detonated—the Trinity Test. It created an enormous mushroom cloud some 40,000 feet high and ushered in the Atomic Age.
How did the Soviets learn about the atomic bomb?
Within days of Britain’s highly classified decision in 1941 to begin research on building an atomic bomb, an informant in the British civil service notified the Soviets. The big breakthrough began in 1946 when the United States, working with Britain, deciphered the code Moscow used to send its telegraph cables.
Who were the two main developers of the atomic bomb?
