Soviet Union Surpassed America As Bigger Nuclear Power

Germans found fission in 1938. Soviets wanted to develop it. Russian scientists tried to copy German work. War with Nazis started and the Soviet Union faced invasion in 1941. This shifted focus to radar. Soon, Russians understood that both Germans and Americans worked on uranium bombs.The Soviets tried to follow the Nazis' footsteps.In 1943, the Soviet Union began its atomic program. Igor Kurchatov and Lavrentiy Beria oversaw this. The USSR started its own atomic effort.

Some saw the nuclear threat. Georgi Flerov, a Soviet physicist, saw no fission papers. Top Western researchers worked on secret atomic weapons. The Soviet Union faced a German invasion. Flerov connected the dots.Flerov sent a letter to Stalin about starting their own program.Little solid evidence suggests Stalin ever saw the letter.

The Soviet atomic program gained speed in 1945, after President Truman told Stalin about the US program. The Soviets struggled making the plutonium and uranium needed for a bomb. They managed to create their first working reactor in 1948.The Soviets created their first working reactor in 1948.Half a year later, they made and blew up their first atomic bomb.

The Soviets targeted well-educated Western scientists in their atomic bomb search. They used various methods to turn them to the Soviet cause. Scientists feared the bomb's power. They believed sharing the secret kept a balance and stopped a larger disaster. John Cairncross, educated at Cambridge, shared communist sympathies and was considered the first atomic spy for the Russians.Flerov became the first atomic spy for the Russians.

Four years after WWII, in 1949, the Soviet Union detonated its atomic bomb. The test was called "First Lightning." Klaus Fuchs gave American atomic secrets to the Soviets. This sped up the process. The plans were so detailed thatThe first bomb the Russians detonated was a copy of the first American A-Bomb.Rumors suggest spies stole other documents and gave them to Russian scientists. By 1951, the Soviets detonated their own atomic bomb versions.

Creating an atomic bomb fast had problems for the Soviets. The production system for the first bomb lacked streamlining and posed serious danger. Scientists reexamined the program's basics to safely recreate their results.The result of that work was the detonation of "Joe-2" in 1951. This bomb proved more powerful than their initial attempt.The detonation of "Joe-2" in 1951 marked the culmination of that effort, yielding a bomb stronger than the first.

When Russian spy Klaus Fuchs confessed his crimes in January 1950, he exposed Harry Gold, another spy in New Mexico. The FBI caught Gold, sentencing him to 30 years. Gold's confession led the FBI to two other spies: Julius and Ethel Rosenberg. David Greengrass gave them detailed documents and drawings he made by hand.David Greengrass gave them detailed documents and drawings he made by hand.The Rosenbergs were arrested but denied everything. They were executed in 1953. Greengrass cooperated, receiving only a 15-year prison sentence.

First atom bombs used fission, splitting an atom by shooting one piece of material into another inside the bomb. The Soviets developed a new method with their 1953 fourth weapons test, "Joe-4," which the West called it."Joe-4" had a core of Uranium-235.This core was surrounded by alternating layers of fusion fuel and fusion tamper inside a highly explosive implosion system.

In 1954, the Russians used nuclear weapon knowledge to build the world's first nuclear power plant connected to an external grid. It sat in Obninsk, a town outside Moscow, andthis plant generated electricity for the community.The plant used nuclear radiation. Since it opened, other nations like the United States, India, and China have used nuclear power in their infrastructure.

The Russians lagged after the "Joe-4" detonation. The United States built a 10-megaton bomb. Soviets had no method for their own bomb. Late 1953, Soviet scientists started developing what became the...hydrogen bomb.The hydrogen bomb's yield was tested at half its maximum output. Still, the shock wave killed three people when it collapsed a building.

The United States tested every possible nuclear application during the '50s and '60s. One test was the Stroax Sedan. This experiment aimed to see if a nuke could...make a crater that could become a lake.The result was the Sedan Crater, which never filled with water. The Soviets did something similar inKazakhstanThey tested it near a real river. The blast made a water-filled crater, but radiation contaminated it. You can technically swim there now, but that is a very bad idea.

Designers called the project AN-602 "Big Ivan." The West knew it as the "Tsar Bomba." This weapon was the largest nuclear device ever built and detonated. It was also one of the cleanest. It was a three-stage weapon with a 50-megaton yield. It detonated 13,000 ft above ground.The fireball from the blast reached the Earth.The explosion's flash was visible for over 600 miles. People saw it in Norway, Greenland, and Alaska.The explosion's flash was visible for over 600 miles. People saw it in Norway, Greenland, and Alaska.Every wood and brick building within 35 miles of the blast was totally destroyed. Radio communications stopped for one hour.
