title: Timeline of the Manhattan Project text: Timeline of the Manhattan Project The Manhattan Project was a research and development project that produced the first atomic bombs during World War II. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the US Army Corps of Engineers. The Army component of the project was designated the Manhattan District; "Manhattan" gradually became the codename for the entire project. Along the way, the project absorbed its earlier British counterpart, Tube Alloys. The Manhattan Project began modestly in title: Code name text: policy of assigning code names intended to give no such clues to the uninitiated. For example, the British counter measures against the V-2 was called "Operation Crossbow". The atomic bomb project centered in New Mexico was called the Manhattan Project, derived from the Manhattan Engineer District which managed the program. The code name for the American A-12 / SR-71 spy plane project, producing the fastest, highest-flying aircraft in the world, was "Oxcart". The American group that planned that country's first ICBM was called the Teapot Committee. Although the word could stand for a menace to shipping (in this case, that title: Manhattan Project text: Manhattan Project The Manhattan Project was a research and development undertaking during World War II that produced the first nuclear weapons. It was led by the United States with the support of the United Kingdom and Canada. From 1942 to 1946, the project was under the direction of Major General Leslie Groves of the U.S. Army Corps of Engineers. Nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory that designed the actual bombs. The Army component of the project was designated the Manhattan District; "Manhattan" gradually superseded the official codename, Development of Substitute Materials, for the entire title: Soviet atomic bomb project text: (including those now in Kazakhstan). The uranium for the Soviet nuclear weapons program came from mine production in the following countries, RDS-1, the first Soviet atomic test was internally code-named "First Lightning" ("Первая молния", or Pervaya Molniya) August 29, 1949, and was code-named by the Americans as "Joe 1". The design was very similar to the first US "Fat Man" plutonium bomb, using a TNT/hexogen implosion lens design. On September 24, 1951, the 38.3 kiloton device RDS-2 was tested based on a tritium "boosted" uranium implosion device with a levitated core. This test was code named "Joe 2" by the title: Soviet atomic bomb project text: Soviet atomic bomb project The Soviet atomic bomb project (Russian: Советский проект атомной бомбы, "Sovetskiy proyekt atomnoy bomby") was the classified research and development program that was authorized by Joseph Stalin in the Soviet Union to develop nuclear weapons during World War II. Although the Soviet scientific community discussed the possibility of an atomic bomb throughout the 1930s, going as far as making a concrete proposal to develop such a weapon in 1940, the full-scale program was initiated during World War II. Because of the conspicuous silence of the scientific publications on the subject of nuclear fission by German, American,
