Joe One, the first Soviet atomic test. Nuclear weapons tests are experiments carried out to determine the effectiveness yield and explosive capability of Nuclear weapons Throughout the twentieth century most nations

The first Soviet atomic bomb, "RDS-1", was an implosion type like the U. S. "Fat Man" bomb, even in appearance; the front "eyes" are radar fuzes. "Fat Man" is the codename for the Atomic bomb that was detonated over Nagasaki, Japan, by the United States on August 9 A proximity fuze (also called a VT fuze for "variable time" is a fuze that is designed to detonate an explosive device automatically when the distance

The RDS-1 (Russian: РДС-1), also Joe-1, was the U. Russian ( transliteration:,) is the most geographically widespread language of Eurasia, the most widely spoken of the Slavic languages S. S. R. 's first nuclear weapon test, named in reference to Joseph Stalin. A nuclear weapon is an explosive device that derives its destructive force from Nuclear reactions either fission or a combination of fission and fusion. Nuclear weapons tests are experiments carried out to determine the effectiveness yield and explosive capability of Nuclear weapons Throughout the twentieth century most nations Joseph Stalin ( ნამდვილი გვარი ჯუღაშვილი|Iosif Vissarionovich Dzhugashvili; March 5 1953 was General Secretary of the Communist Party It was test-exploded on August 29, 1949, at Semipalatinsk, Kazakhstan, U. Events 708 - Copper coins are minted in Japan for the first time (Traditional Japanese date: August 10, 708) Year 1949 ( MCMXLIX) was a Common year starting on Saturday (link will display the full calendar of the Gregorian calendar. The Semipalatinsk Test Site (STS was the primary testing venue for the Soviet Union 's Nuclear weapons. Kazakhstan, also Kazakstan ( Қазақстан, Qazaqstan, qɑzɑqˈstɑn Казахстан, Kazakhstán,) officially the S. S. R.

The Joe-1 explosion yielded 22 kilotons of TNT force, similar to the U. Units of mass There are three similar units of Mass called the ton: Long ton (simply ton in countries such as the United Trinitrotoluene ( TNT) is a Chemical compound with the formula C6H2(NO23CH3 S. 's "Gadget" and "Fat Man" bombs. " The gadget " was the code-name given to the first nuclear explosive developed under the Manhattan Project during World War II, which was "Fat Man" is the codename for the Atomic bomb that was detonated over Nagasaki, Japan, by the United States on August 9 At Lavrenty Beria's insistence, the RDS-1 bomb was designed like the "Fat Man" bomb dropped on Nagasaki, Japan. Lavrentiy Pavlovich Beria (ლავრენტი პავლეს ძე ბერია Lavrenti Pavles dze Beria; Russian: Лаврентий Павлович ( is the Capital and the largest city of Nagasaki Prefecture in Japan. For a topic outline on this subject see List of basic Japan topics. The Soviets called it Lightning's First Strike (Первая молния, Pervaya molniya), and its development surprised complacent American military-intelligence. Later, they discovered that the Soviets' extensive Manhattan Project knowledge came from spies such as Klaus Fuchs, and Julius and Ethel Rosenberg, among others. The World War II Manhattan Project developed the first Nuclear weapon (atomic bomb Klaus Emil Julius Fuchs ( December 29, 1911 &ndash January 28, 1988) was a German -born theoretical physicist and Julius Rosenberg (May 12 1918 &ndash June 19 1953 and Ethel Greenglass Rosenberg (September 28 1915 &ndash June 19 1953 were American Communists who were executed

There are several explanations for the U. S. S. R. code-name of RDS-1, usually an arbitrary designation, a backronym" "Stalin's Rocket Engine" (Реактивный двигатель Сталина, Reaktivnyi Dvigatel Stalina), or "Russia does it herself" (Россия делает сама, Rossiya Delayet Sama); later weapons were designated RDS, with different model numbers. A backronym (or bacronym) is a Phrase that is constructed "after the fact" from a previously existing word or Abbreviation, the abbreviation
