Project Plum Bob

Project Plum Bob was a covert U.S. military initiative during the Cold War, primarily in the 1960s, focused on developing nuclear test detection technologies. It sought to enhance surveillance capabilities to monitor and verify nuclear activities of other nations. By improving the detection of underground nuclear tests, the project aimed to bolster national security and ensure compliance with international arms control agreements. The name "Plum Bob" is derived from a type of weight used in construction, symbolizing precision and the project's aim to achieve accurate measurements in nuclear monitoring efforts.
