Editing Soviet atomic bomb project (section)

=== RDS-1 ===
The [[RDS-1]], ([[Russian language|Russian]]: PДC), was the first Soviet nuclear device that was test fired in [[Semipalatinsk Test Site|Semipalatinsk]] in [[Kazakh SSR|Kazakhstan]] on August 29, 1949. The first [[atomic test|nuclear test]], that proved the [[Russia]]'s nuclear capability, has many codenames within Russian political community including the internally code-named ''First Lightning'' (''Первая молния'', or Pervaya Molniya).

Nonetheless, the test was widely known as "RDS-1" (''Россия делает сама,'' Rossiya Delayet Sama, which translate as "Russia Does it Herself"), which was suggested by [[Igor Kurchatov]]– all Russian nuclear tests were then followed the ''RDS'' nomenclature. The [[United States|Americans]] codenamed the test as ''Joe 1''. The energy yield measurement and its design was mostly based on the American design "[[Fat Man]]", using a [[Trinitrotoluene|TNT]]/[[hexogen]] implosion lens design.
