Operation Sandstone was the third American series of nuclear weapon tests. The United States of America —commonly referred to as the A nuclear weapon is an explosive device that derives its destructive force from Nuclear reactions either fission or a combination of fission and fusion. It was conducted in 1948 at Enewetak Atoll. Year 1948 ( MCMXLVIII) was a Leap year starting on Thursday (link will display the 1948 calendar of the Gregorian calendar. Enewetak (or Eniwetok) is an Atoll in the Marshall Islands of the central Pacific Ocean. These tests followed Crossroads and preceded Ranger. Operation Crossroads was a series of Nuclear weapon tests conducted by the United States in the summer of 1946 Operation Ranger was the fourth American nuclear test series It was conducted in 1951 and was the first series to be carried out at the Nevada Test Site As was the custom, each explosion was given a nickname.

The tests were authorized on June 27, 1947 and Enewetak Atoll was chosen as the test site on October 11.

The tests were used to evaluate new atomic weapon designs that had been developed at Los Alamos as part of the Manhattan Project but had not previously been used. Los Alamos National Laboratory (LANL (previously known at various times as Site Y, Los Alamos Laboratory, and Los Alamos Scientific Laboratory) is a The World War II Manhattan Project developed the first Nuclear weapon (atomic bomb The bombs used oralloy, a form of enriched uranium, as a replacement for plutonium, which had been used in all atomic weapons prior to this with the exception of the "Little Boy" bomb dropped on Hiroshima, which utilized uranium-235. Enriched uranium is a kind of Uranium in which the percent composition of Uranium-235 has been increased through the process of Isotope separation. Uranium (jʊˈreɪniəm is a silvery-gray Metallic Chemical element in the Little Boy was the Codename of the Atomic bomb, developed via the "Manhattan Project" which was dropped on Hiroshima, on August 6 1945 by the The Japanese city of ( is the capital of Hiroshima Prefecture, and the largest city in the Chūgoku region of western Honshū, the largest of Japan 's Uranium-235 is an isotope of uranium that differs from the element's other common isotope Uranium-238, by its ability to cause a rapidly expanding fission The X-Ray test used a 2:1 mix of oralloy and plutonium. The Yoke and Zebra tests used all oralloy.
