Project Manhattan

The Manhattan Project was a secret U.S. research initiative during World War II focused on developing the first atomic bomb. Beginning in 1939 and accelerating in the early 1940s, scientists and engineers worked across multiple sites to unlock nuclear fission's potential for powerful weaponry. The project combined scientific innovation with significant logistical efforts, culminating in the successful test of the bomb in 1945. This development profoundly impacted warfare, geopolitics, and ethics, marking a pivotal moment in history by introducing nuclear weapons and altering the future of military technology.
