True. The purpose of the Manhattan Project was indeed to develop an atomic bomb with the aim of ending World War II. It was a top-secret research project that began during World War II and involved a collaboration of scientists, engineers, and military personnel from the United States, the United Kingdom, and Canada. The project successfully produced the world's first atomic bombs, which were eventually used against Japan in August 1945. The bombings of Hiroshima and Nagasaki led to Japan's surrender, effectively bringing an end to the war in the Pacific.
