Explanation:

The Manhattan Project was a research and development project carried out

The Manhattan Project was a research and development project carried out during the Second World War that produced the first nuclear weapons, 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 Army Corps of Engineers of the United States, while the nuclear physicist Robert Oppenheimer was the director of the Los Alamos Laboratory in which the nuclear bombs were designed .

Two types of atomic bombs were developed simultaneously during the war: a relatively simple ballistic-type fission weapon and a more complex implosion nuclear weapon. The fission design of the Thin Man pump proved impractical for use with plutonium, so a simpler weapon called Little Boy was developed using uranium-235, an isotope that constitutes only 0.7% of the uranium in natural state.
