On August 6, 1945, B-29 Superfortress “Enola Gay” dropped the world’s first atomic weapon on Hiroshima, Japan. Three days later, “Bockscar” carried the second bomb to Nagasaki. Within a month, World War II was over. But that’s not the end of the story!

In September 1942 America embarked on one of the most ambitious scientific and industrial endeavors in history: the Manhattan Project. It would cost over two billion dollars—$20 billion today— and employ over 130,000 people. With the project cloaked in secrecy, only a handful knew we were in a race against Nazi Germany to build the world’s first atomic bomb.

It took only a few years for the secrets of the atomic genie to become known to others — friends and enemies alike. To date, at least nine nations have weapons of mass destruction and others may be close to joining the elite nuclear club.

In this captivating episode of “War Stories with Oliver North,” you’ll meet Bill Wilcox, Roger Rohrbacher and Gladys Owens—three pioneers who helped build the first atomic bomb. You’ll also learn from renowned international weapons inspector David Kay just how we hunt for nuclear weapons today, and why we should be worried about a nuclear Iran.

Come along as “War Stories” explores the secrets of the bomb — from the Manhattan Project to Tehran.
