How could the US detonate a bomb on the Moon?

TL;DR
The plan called Project A119 proposed sending a nuclear warhead to the Moon to create a visible mushroom cloud as a warning of American power. NASA considered it but rejected the idea due to fears of misfire and triggering a Soviet response. The episode documents this near miss and related Cold War covert acts.

Key Insights
- Project A119 was a real, secretly discussed plan to detonate a nuclear device on the Moon as a show of force. The plan used a W25 warhead with a 1.7 kiloton yield strapped to a missile for a lunar detonation. The proposal aimed to leave a visible, lasting American crater as a warning signal.
- The mission was met with concerns that a misfire could occur, causing damage or triggering a Soviet nuclear response, potentially escalating to full scale war. These risks led to the plan being shut down.
- NASA initially considered the idea within a broader push to catch up with Soviet space achievements, reflecting the urgency and fear of the space race during the Cold War.
- The episode situates the lunar detonation plan within a larger context of aggressive, sometimes absurd strategies explored by military and intelligence communities.
- In addition to space, the video recounts MI6 operations such as Tamarisk, which exploited Soviet material shortages to gather intelligence, including torn and used paper from latrines.
- The Winnipeg If Day stunt demonstrates another facet of wartime morale campaigns, using a Nazi occupation mock to raise war bonds, illustrating propaganda as a tool of national effort.
- The narrative shows how extreme ideas can be both technically possible and strategically rejected due to risk, ethics, and international consequences.
- Overall, the episode blends myth, memory, and factual record to reveal how fear influenced extraordinary proposals in history.
