What was the top-secret mission to develop an atomic weapon called?

• A. Manhattan Project
• B. Enigma Project
• C. Trinity Project
• D. Apollo Project

Answer: (A)

The wartime effort to develop an atomic weapon was called the Manhattan Project. This massive, top-secret program brought together scientists, engineers, and military leaders from the United States and its allies starting in 1942, with key sites at Los Alamos for weapon design, Oak Ridge for uranium enrichment, and Hanford for plutonium production. Leading scientists like J. Robert Oppenheimer and military overseer General Leslie Groves guided the work, which aimed to build a functional atomic bomb before enemies could do so. The project ultimately produced the first nuclear weapons and carried out the Trinity test—the first detonation—in New Mexico in 1945. For context, Enigma relates to breaking German codes, Trinity is the first test explosion itself, and Apollo was NASA’s Moon program.
