The second most important state when it comes to researching, developing, and then storing nuclear weapon. Although the Russians managed to catch up with Americans later on, it was only in 1949 that the first nuclear test conducted by then the Soviet Union occurred. It was still quite a surprise for the Western Powers, who believed that Russia won’t be capable of producing nuclear warheads until 1953-1954. After the first test, the nation in question started to rapidly increase the amount of warheads they possessed. In the end of 1980s, they were the leading power when it comes to total number of warheads stored. It was approximately 40,000 warheads.
Nowadays, similarly to United States, the Russians store a total number of 6490 warheads, what is scarcely more than USA. When it comes to the number of deployed warheads, the amount is the same as in case of Americans, namely 1600 deployed warheads. We should also remember about the fact that Russia conducted over 700 tests, what makes them the second most important nation when it comes to developing nuclear weapons. However, it was the Soviet Union that managed to create the biggest bomb in the world. Known as Tsar Bomba, it had blast yield of 50 megatons of TNT.
