Though America and Britain were allies with Russia, in the fight against Germany, Russia was always viewed with suspicion by America and Britain. Which is why, at the end of the war, the Americans hastened to spirit away the German scientists who had been working on rocket propulsion and guidance systems of the V2 rockets, to the USA, before the Russians could capture them. So, naturally, each ally had many secrets that were not divulged to anyone.

The building of the atomic bomb was known as the Manhattan Project. It was a research and development project during World War II that produced the first nuclear weapons.

Klaus Fuchs, a German-born physicist, played a minor but significant role in passing atomic secrets to the Soviets during and after World War II. He worked on the Manhattan Project and provided important information about nuclear weapons, which aided the Soviet atomic bomb program. Fuchs was arrested in 1950 and later confessed to espionage, highlighting the extent of Soviet infiltration into American atomic research. His actions contributed to the Cold War's nuclear arms race.
The Soviet Union successfully tested its first atomic bomb on August 29, 1949. This test, known as "First Lightning" or "Joe 1," marked the beginning of the nuclear arms race during the Cold War, as it demonstrated that the Soviets had developed nuclear capabilities shortly after the United States. The test took place at the Semipalatinsk Test Site in Kazakhstan.

No. By the time the US dropped the atomic bomb on Japan, Germany had already surrendered. While Germany did have a nuclear weapons program during the war, it did not actually get to the point that they were capable of building a working bomb.
