Castle Bravo

When it comes to Nuclear bombs there's large and then there's Castle Bravo. On March 1st, 1954 the United States detonated the largest Thermonuclear weapon in the world. The Castle Bravo explosion wouldn't be topped for nearly 10 years. To this day, it holds the spot as the largest explosion ever caused by the United States and sits as the fifth largest man-made detonation of all time. This is the story of how the Castle Bravo bomb stunned researchers and brought about an international call to ban such thermonuclear testing.
