The attack was scheduled for June 1945, according to the interrogation minutes of Werner Waechter - a close associate of the Minister of Propaganda Nazi Germany Joseph Goebbels. The declassified document has been published by the Federal Security Service of the Russian Federation (FSB) - RT reported.
The release of the testimony coincided with the 79th anniversary of the US atomic bombing of Hiroshima, Japan at the end of World War 2, on August 6, 1945.
According to copies of documents related to the case of the former Nazi official, the nuclear attacks would be carried out by using "long-range bombers capable of bombing military construction centers of USSR in the Urals".
In his testimony in October 1945, Wachter told Soviet investigators that he knew about the development of atomic weapons from a Nazi engineer in 1943.
He said that German scientists had "succeeded in splitting atomic nuclei and engineers were developing methods and techniques to use atomic energy as a means of warfare".
At the end of the 1930s, German scientists discovered the fission of uranium atoms and made significant contributions to the foundation of atomic physics. Nazi Germany was the first country to launch a concentrated project to create an atomic bomb.
Wachter also said that in 1945, the editor of the government's secret news bulletin, Hans Hertel, told him that the German Ministry of Armaments was preparing to use an atomic bomb, intended to be equipped on a "newly designed" aircraft stationed at an airfield near the town of Celle in northern Germany.
Although uncertain about the exact date of the nuclear attack plan, Wacher believed that June was the most likely time for Hitler to deploy the new weapon, especially when Minister of Propaganda Joseph Goebbels ordered a special astrological chart for Hitler in that month.
The Third Reich frequently used astrology as a means of propaganda to predict future events and popularize them among the people.
According to FSB records, Hitler's plan to use nuclear weapons against the USSR ultimately failed in May 1945, when Soviet forces captured Berlin and forced Nazi Germany to surrender.
Although Germany was the first country to attempt to create an atomic bomb, the project was never completed. Meanwhile, the US developed atomic bombs at the end of the war and became the first and only country to use this deadly weapon in a military conflict, when it dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945 - 79 years ago.
The atomic bombings resulted in the deaths of over 200,000 people in Japan, mostly civilians.
