The BBC Future article discusses a once-secret plan developed during the Cold War era to detonate a nuclear bomb on the Moon. This plan, “Project A119” or “A Study of Lunar Research Flights,” was a top-secret United States Air Force project devised in the late 1950s.
At the height of the Cold War, the United States and the Soviet Union were locked in a race for supremacy in space. During this time, the U.S. Air Force initiated Project A119, which aimed to demonstrate the nation’s technological prowess by detonating a nuclear bomb on the Moon. The project was primarily intended as a show of force and a means to intimidate the Soviet Union.

The plan involved launching a nuclear device on a rocket and detonating it upon impact with the lunar surface. The explosion would have been visible from Earth, creating a significant psychological impact. The project’s scientific goals include studying the effects of a nuclear explosion in a low-gravity environment and analyzing the lunar surface’s composition after the blast.
Project A119 was eventually cancelled due to several factors, including concerns about the potential negative public reaction, the growing realization of the potential consequences of nuclear fallout, and the risk of the mission failing and the nuclear device crashing back to Earth.
As the space race evolved, the United States and the Soviet Union shifted their focus to more peaceful endeavours, such as landing humans on the Moon and conducting scientific research. In 1969, the U.S. achieved a major milestone in the space race with the successful Apollo 11 mission, which saw astronauts Neil Armstrong and Buzz Aldrin becoming the first humans to set foot on the Moon.
The revelation of Project A119 highlights the extreme measures that were considered during the Cold War and served as a cautionary tale about the potential consequences of unchecked competition and the militarization of space.
