👉 The Manhattan weapon, also known as the atomic bomb, is a highly destructive nuclear weapon developed during World War II by the United States, primarily through the Manhattan Project. It harnesses the power of nuclear fission, where the nucleus of an atom splits into smaller parts, releasing a massive amount of energy. This weapon consists of two main components: a "gun" that accelerates a subcritical mass of uranium or plutonium to initiate a chain reaction, and a "implosion" device that compresses the fuel core to achieve the necessary conditions for a sustained nuclear reaction. The resulting explosion generates immense heat and radiation, capable of causing widespread devastation over a large area, making the Manhattan weapon one of the most powerful and feared weapons in history.
