Britain's connection to nuclear weapons uncovered in chilling report, revealing potential risks to our safety
Eighty years ago, the world was forever changed with the dropping of an atomic bomb on the Japanese city of Hiroshima. This momentous event was a culmination of years of scientific research and development, much of which was initiated by the Frisch-Peierls Memorandum.
Written by Otto Frisch and Rudolf Peierls, two nuclear physicists who had fled Nazi Germany, the memorandum provided the first clear scientific proof that an atomic bomb was achievable. The document, submitted confidentially to the British government in 1940, detailed the physics behind nuclear fission, the concept of critical mass, and the potential explosive power of a uranium-235 based bomb.
Frisch and Peierls, working at the University of Birmingham in Britain during World War II, were motivated by the fear that Nazi Germany might develop an atomic bomb first. They calculated the critical mass of uranium-235 needed for a bomb and showed it was much smaller than previously assumed—making the construction of an atomic bomb feasible and practical.
The memorandum also discussed means of uranium enrichment and anticipated the strategic and ethical implications of nuclear weapons. This groundbreaking document spurred immediate action, leading to the establishment of the MAUD Committee, which urged bomb development and collaboration with the United States.
This British initiative was influential in triggering the subsequent Tube Alloys project and then the Manhattan Project, which built the first atomic bombs. The bombs dropped on Hiroshima and Nagasaki, with the explosive power of around 16 and 20 kilotonnes of TNT respectively, were a testament to the success of these projects.
Today, nine countries possess nuclear weapons: the US, Russia, China, France, the UK, India, Pakistan, North Korea, and Israel. Modern nuclear weapons, such as the W76 thermonuclear warhead, are much more powerful than the bombs dropped on Japan. For instance, the largest warhead in America's current arsenal, the B83, has the explosive equivalent of 1.2 megatonnes (1.2 million tonnes of TNT).
The current nuclear situation is more precarious than in 1963 due to the confluence of new existential risks like the military use of AI and climate change. It is a stark reminder of the importance of the Frisch-Peierls Memorandum and the role it played in shaping the world we live in today.
