Anniversary of the Explosion of the First Hydrogen Bomb

November 1, 1952
Published: July 31, 2023

Hydrogen bombs are 1000 times more powerful than the atomic bombs dropped on Hiroshima and Nagasaki during World War II. On January 31, 1950, U.S. President Harry S. Truman announced his controversial decision to pursue the research and production of thermonuclear weapons. The United States conducted its first hydrogen bomb test at Eniwetok Atoll in the Pacific on this day in 1952. The H-Bomb cloud rose to a height of about 25 miles at its peak. By the late 1970s, seven nations constructed their own hydrogen bombs.
