RDS-1
The RDS-1 (), also known as Izdeliye 501 (device 501) and First Lightning (), was the nuclear bomb used in the Soviet Union's first nuclear weapon test. The United States assigned it the code-name Joe-1, in reference to Joseph Stalin. It was detonated on 29 August 1949 at 7:00 a.m., at the Semipalatinsk Test Site, Kazakh SSR, after top-secret research and development as part of the Soviet atomic bomb project. Etymology There are several explanations for the Soviet code-name of RDS-1, usually an arbitrary designation: a backronym "Special Jet Engine" (, ''Reaktivnyi Dvigatel Spetsialnyi''), or "Stalin's Jet Engine" (, ''Reaktivnyi Dvigatel Stalina''), or "Russia does it herself" (, ''Rossiya Delayet Sama''). Later weapons were also designated RDS but with different model numbers. Description The weapon was designed at the Kurchatov Institute, then at the time officially known as "Laboratory № 2" but designated as the "office" or "base" in internal documents, sta ...

Soviet Atomic Bomb Project
The Soviet atomic bomb project was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during and after World War II. Russian physicist Georgy Flyorov suspected that the Allied powers were secretly developing a " superweapon" since 1939. Flyorov urged Stalin to start a nuclear program in 1942. Early efforts mostly consisted of research at Laboratory No. 2 in Moscow, and intelligence gathering of Soviet-sympathizing atomic spies in the US Manhattan Project. Subsequent efforts involved plutonium production at Mayak in Chelyabinsk and weapon research and assembly at KB-11 in Sarov. After Stalin learned of the atomic bombings of Hiroshima and Nagasaki, the nuclear program was accelerated through intelligence gathering about the Manhattan Project and German nuclear weapon project. Espionage coups, especially via Klaus Fuchs and David Greenglass, included detailed descriptions of the implosion-type Fat Man bomb and plutonium production. In the final mo ...

RDS-2
The RDS-2 (Russian: РДС-2) was the second atomic bomb developed by the Soviet Union as an improved version of the RDS-1. It included new explosive lenses along with a new core design to decrease the probability of pre-detonation or 'fizzle'. The RDS-2 weighed approximately and had a diameter of 1.25 m. The RDS-2 was tested on September 24, 1951 and produced a 38.3 kiloton yield. It was detonated from the top of a tower thirty meters high. The detonation was initiated by a bomber flying over the testing site instead of the detonation being initiated by a ground control center. See also *Soviet atomic bomb project *RDS-1 *RDS-3 RDS-3 () was the third atomic bomb developed by the Soviet Union in 1951, after the RDS-1 and RDS-2. It was called ''Marya'' in the military. The bomb had a composite design with a plutonium core inside a uranium shell, providing an explosive powe ...

Fat Man
"Fat Man" (also known as Mark III) was the design of the nuclear weapon the United States used for seven of the first eight nuclear weapons ever detonated in history. It is also the most powerful design to ever be used in warfare. A Fat Man device was Atomic bombings of Hiroshima and Nagasaki#Bombing of Nagasaki, detonated over the Japanese city of Nagasaki on 9 August 1945. It was the second and largest of the only two nuclear weapons ever used in warfare. It was dropped from the Boeing B-29 Superfortress ''Bockscar'' piloted by Major Charles Sweeney. Its detonation marked the third nuclear explosion in history. The name Fat Man refers to the wide, round shape. Fat Man was an implosion-type nuclear weapon with a solid plutonium Nuclear reactor core, core, and later with improved cores. The first Fat Man to be detonated was the gadget in the Trinity (nuclear test), Trinity nuclear test less than a month earlier on 16 July at the Holloman Air Force Base, Alamogordo Bombing an ...

Nuclear Weapon Test
Nuclear weapons tests are experiments carried out to determine the performance of nuclear weapons and the effects of their explosion. Nuclear testing is a sensitive political issue. Governments have often performed tests to signal strength. Because of their destruction and fallout, testing has seen opposition by civilians as well as governments, with international bans having been agreed on. Thousands of tests have been performed, with most in the second half of the 20th century. The first nuclear device was detonated as a test by the United States at the Trinity site in New Mexico on July 16, 1945, with a yield approximately equivalent to 20 kilotons of TNT. The first thermonuclear weapon technology test of an engineered device, codenamed Ivy Mike, was tested at the Enewetak Atoll in the Marshall Islands on November 1, 1952 (local date), also by the United States. The largest nuclear weapon ever tested was the Tsar Bomba of the Soviet Union at Novaya Zemlya on October 30, 1961, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Weapon Yield
The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated. It is usually expressed as a ''TNT equivalent'', the standardized equivalent mass of trinitrotoluene (TNT) which would produce the same energy discharge if detonated, either in kilotonnes (symbol kt, thousands of tonnes of TNT), in megatonnes (Mt, millions of tonnes of TNT). It is also sometimes expressed in terajoules (TJ); an explosive yield of one terajoule is equal to . Because the accuracy of any measurement of the energy released by TNT has always been problematic, the conventional definition is that one kilotonne of TNT is held simply to be equivalent to 1012 calories. The yield-to-weight ratio is the amount of weapon yield compared to the mass of the weapon. The practical maximum yield-to-weight ratio for fusion weapons (thermonuclear weapons) has been estimated to six megatonnes of TNT per tonne of bomb ...

Plutonium
Plutonium is a chemical element; it has symbol Pu and atomic number 94. It is a silvery-gray actinide metal that tarnishes when exposed to air, and forms a dull coating when oxidized. The element normally exhibits six allotropes and four oxidation states. It reacts with carbon, halogens, nitrogen, silicon, and hydrogen. When exposed to moist air, it forms oxides and hydrides that can expand the sample up to 70% in volume, which in turn flake off as a powder that is pyrophoric. It is radioactive and can accumulate in bones, which makes the handling of plutonium dangerous. Plutonium was first synthesized and isolated in late 1940 and early 1941, by deuteron bombardment of uranium-238 in the cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which then beta-decayed to form the new element with atomic number 94 and atomic weight 238 (half-life 88 years). Since uranium had been named after the planet Uranus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julius And Ethel Rosenberg
Julius Rosenberg (May 12, 1918 – June 19, 1953) and Ethel Rosenberg (born Greenglass; September 28, 1915 – June 19, 1953) were an American married couple who were convicted of First Chief Directorate, spying for the Soviet Union, including providing top-secret information about American radar, sonar, jet propulsion engines, and nuclear weapon designs. Convicted of espionage in 1951, they were Capital punishment by the United States federal government, executed by the federal government of the United States in 1953 using New York's state execution chamber in Sing Sing in Ossining (village), New York, Ossining, New York, becoming the first American civilians to be executed for such charges and the first to be executed during peacetime.

Mayak
The Mayak Production Association (, , from 'lighthouse') is one of the largest nuclear facilities in the Russian Federation, housing Production reactor, production reactors (''non'' electricity) and a reprocessing plant. The closest settlements are Ozyorsk, Chelyabinsk Oblast, Ozyorsk to the northwest and Novogornyi to the south. Lavrentiy Beria led the Soviet atomic bomb project. He directed the construction of the Mayak plutonium plant in the Southern Urals between 1945 and 1948, in a great hurry and secrecy as part of the Soviet Union's Soviet atomic bomb project, atomic bomb project. The plant had a similar purpose to the Hanford Site of the Manhattan Project. Over 40,000 gulag prisoners and POWs built the factory and the closed nuclear city of Ozyorsk, called at the time by its classified postal code "Chelyabinsk-40". The first reactor, A-1 (nuclear reactor), A-1, operated from 1948 and fuelled the first nuclear test RDS-1 in 1949. During the Cold War, 10 nuclear reactors ...
