Recognizing 75 Years of Nuclear Deterrence 'Fat Man' was dropped from the B-29 bomber Bockscar, detonating at 11:02 AM, at an altitude of about 1,650 feet (500 m) above Nagasaki. An estimated 39,000 people were killed outright by the bombing; a further 25,000 were injured.
A group of individuals (both men and women) all played a significant role in maintaining Nuclear Deterrence over the past 75 years. Not just the obvious military personnel who served as crews of the nuclear deterrence forces (bombers, ICBM silos and nuclear submarines, as well as tactical weapon platforms) but also those who provided supporting efforts in the production of these forces, the training needed, and, like me, the war planning for our nuclear forces.
