What Was the US Army's Secret Plan for the Moon?

TL;DR

The US Army's Project Horizon was a secret plan in the 1960s to establish a lunar outpost and defend it using fragmentation weapons. The plan outlined detailed strategies for construction, technology, and weaponry tailored to the moon's unique environment, emphasizing the use of explosive devices over traditional firearms. Ultimately, the project was shelved due to political and logistical challenges, including the Outer Space Treaty.

Questions & Answers

Q: What was Project Horizon and why was it developed?

Project Horizon was a top-secret plan by the US Army to establish a lunar outpost. It was developed in response to the Soviet Union's success in space, with the goal of not falling behind in the space race.

Q: What were the key recommendations of Project Horizon for lunar base defense?

The plan prioritized the use of fragmentation weapons such as mines for perimeter defense. If the enemy breached the perimeter, modified handheld shotguns were suggested as handheld weapons.

Q: How did the lunar environment affect the effectiveness of weapons?

The low gravity and lack of atmosphere on the moon posed challenges for traditional weapons. Firing a pistol, for example, would have higher recoil and be more difficult to control in a vacuum. Bullets would also travel in extended ballistic arcs.

Q: What led to the demise of Project Horizon?

The signing of the Outer Space Treaty in 1967, which prohibited military operations on celestial bodies, made Project Horizon officially impossible. Additionally, the cost and political implications of the project were significant.

Summary & Key Takeaways

• Project Horizon was the US Army's detailed plan to create and maintain a lunar outpost in response to the Soviet Union's success in space exploration.

• The declassified report outlined specific recommendations for launch and landing sites, living quarters, and the use of nuclear-powered rockets.

• The plan prioritized perimeter defense using fragmentation weapons like mines, and suggested modifying handheld guns to function as shotguns in the lunar environment.
