How did the Soviet Union acquire the knowledge for nuclear weapons?
Initial efforts were slowed due to the German invasion of the Soviet Union and remained largely composed of the intelligence knowledge gained from the Soviet spy rings working in the U.S. Manhattan Project.
When did Russia obtain nuclear weapons?
29 August 1949
On 29 August 1949, the Soviet Union conducted its first nuclear test, code-named ‘RDS-1’, at the Semipalatinsk test site in modern-day Kazakhstan. The device had a yield of 22 kilotons.
Why did Russia build nuclear weapons?
Russia relies heavily on nuclear weapons to offset its own perceived inferiority of its conventional forces in a conflict with the forces of the North Atlantic Treaty Organization. Despite economic challenges, Russia is building up its nuclear forces, and in some areas could gain an advantage over the United States.
Is Russia developing new nuclear weapons?

How did the atomic bomb create tension between US and USSR?
In 1949, the USSR tested its first atomic bomb. This led to a race between the two superpowers to amass the most powerful nuclear weapons with the most effective delivery systems. Tension was greatly increased as a result of the developing arms race which served to militarise both sides and bring war closer.
How did the Soviet Union build the atomic bomb?
Over the next four years the full resources of the Soviet Union were mobilized to build the bomb, including extensive use of prison labour from the Gulag to mine uranium and build the plants. The first Soviet chain reaction took place in Moscow on December 25, 1946, using an experimental graphite-moderated natural uranium pile known as F-1.

How did the Soviet Union develop nuclear fission?
Throughout 1939, leading Soviet physicists attempted to reproduce the fission experiment that Otto Hahn and Fritz Strassmann had conducted in Berlin and began to make measurements and calculations to determine under exactly what conditions, if any, a nuclear chain reaction would take place.
