The Pentagon already had a plan for a permanent armed Moon base in 1959
In March 1959, before a single human had reached space, the US Army ordered a feasibility study for something far more ambitious than a flag-and-footprints landing: a permanent, nuclear-powered military outpost on the Moon, staffed by soldiers, armed, and operational by December 1966. The final report, submitted to the Pentagon that June, is real, declassified, and held today at the Smithsonian’s National Air and Space Museum. Eisenhower rejected it in favor of NASA’s civilian program. The idea it proposed, a permanent human foothold on the Moon rather than a brief visit, is the exact pitch now being made again in 2026.

Trudeau, the Army’s Chief of Research and Development, tasked the Army Ballistic Missile Agency, led by Wernher von Braun, with studying the feasibility of a lunar military outpost. The order came in the immediate aftermath of Sputnik, when each US military branch still ran its own independent space program and losing the Moon to the Soviet Union outright was treated as a real strategic risk, not a hypothetical one.
The final report, Project Horizon: A U.S. Army Study for the Establishment of a Lunar Military Outpost, ran to two volumes and was submitted June 8, 1959. It called for a base staffed by 10 to 12 soldiers, operational by December 1966, powered by nuclear reactors, and requiring roughly 150 Saturn rocket launches to deliver over 220,000 kilograms of cargo. The estimated cost was $6 billion, on the order of $64 billion in 2025 dollars. The outpost’s stated purpose combined genuine scientific research with an explicitly military one: surveillance of Earth and space, a communications relay, and if required, a base for lunar military operations. The plan even specified modified anti-personnel mines adapted to function in the Moon’s temperature extremes.
President Eisenhower rejected Project Horizon in favor of a civilian space program, a decision that led directly to NASA absorbing responsibility for the American Moon effort. When that responsibility transferred, Project Horizon was formally cancelled. The 1969 landing the country remembers was the civilian version of a much larger military ambition that had already been costed out, planned in detail, and shelved a decade earlier.
This establishes that a real, declassified 1959 US Army study proposed a permanent, staffed, armed military outpost on the Moon in specific technical and budgetary detail, that the study was formally submitted to the Pentagon, and that it was rejected in favor of the civilian program the public actually remembers. This is confirmed by the report itself, held today in the Smithsonian’s archive.
What this does not establish is that any current proposal for a permanent Moon presence is directly descended from Project Horizon specifically, or that today’s advocates are aware of it. The resemblance in language and ambition is real and worth noting. A direct institutional lineage between the two is not documented.
