24. Germany’s Atomic Missteps
Germany’s chief nuclear physicist, Werner Heisenberg, had nebulous ideas that splitting the atom could produce a powerful weapon. However, he never figured out how to weaponize nuclear fission. In their last test in the spring of 1945, German scientists failed to achieve the preliminary first step of criticality – a self-sustaining chain reaction that the Manhattan Project had achieved in 1942. Criticality was the crucial foundation, without an atomic weapon program could not have succeeded.
Additionally, the German nuclear program lacked necessary support. After achieving criticality, it took America another three years, with a massive investment of resources and the personal support and attention of the head of state, to successfully test the first atomic bomb. The Germans had not accomplished the criticality breakthrough by the time the war ended, and their nuclear program had never received anything close to the support enjoyed by the Manhattan Project.
