In 1945, as Allied forces swept through the ruins of Nazi Germany, American intelligence officers raced to find the scientists behind Hitler’s most advanced weapons. What they found changed the course of the Cold War, the Space Race, and the moral foundations of American intelligence.

The men who designed the V-2 rockets that terrorized London were given new names, new histories, and new careers in the United States. Their Nazi Party memberships were erased. Their SS ranks were buried in classified files. Their connections to concentration camp slave labor were scrubbed from the record. The program was called Operation Paperclip, and it would recruit more than 1,600 German scientists over the next fourteen years.

The Detail That Changes Everything

Wernher von Braun held the rank of Sturmbannführer in the SS. Twenty thousand prisoners died building his V-2 rockets at the Mittelbau-Dora concentration camp. After the war, the United States made him the father of the American space program. Arthur Rudolph supervised slave labor at Mittelbau-Dora. He designed the Saturn V rocket that landed Americans on the moon.

The Devil’s Bargain

On August 28, 1945, the Joint Chiefs of Staff authorized Operation Overcast, the precursor to Paperclip. The directive was clear: recruit German scientists before the Soviets could get them. President Truman explicitly prohibited entry for anyone who had been an active supporter of Nazi militarism. American intelligence officers solved this problem by falsifying the scientists’ records. SS memberships disappeared. Party affiliations were downplayed. War crimes were reclassified as administrative service.

By September 1946, a new directive formally expanded the program and overruled Truman’s restrictions. The Cold War had begun, and technical expertise outweighed moral accountability.

Key Figures

Wernher von Braun arrived in the United States in 1945 with 127 German rocket scientists. He held 355 patents, spoke five languages, and had overseen the deaths of twenty thousand concentration camp prisoners at Mittelbau-Dora. He became the most celebrated rocket engineer in American history and the chief architect of the Apollo program.

Arthur Rudolph supervised slave labor production of V-2 rockets at Mittelbau-Dora before designing the Saturn V rocket for NASA. When the Justice Department investigated his war crimes in the 1980s, he surrendered his American citizenship and left the country rather than face trial.

Kurt Debus was an active SS officer who reported colleagues to the Gestapo. He became the first director of the Kennedy Space Center and oversaw every Apollo launch.

Hubertus Strughold directed high-altitude medical experiments on concentration camp prisoners at Dachau. He became known as the Father of Space Medicine and received numerous American honors before his Nazi past resurfaced.

Linda Hunt was the investigative journalist whose 1984 Freedom of Information Act request uncovered 130,000 classified pages that blew the entire operation wide open.

Jean Michel was a French Resistance fighter and Mittelbau-Dora survivor who testified before Congress in 1984, forty years after the scientists he watched torture prisoners were given American citizenship and celebrated as heroes.

The Reckoning That Never Came

On July 20, 1969, when Neil Armstrong stepped onto the lunar surface, three former Nazi scientists stood in Mission Control: Wernher von Braun, Arthur Rudolph, and Kurt Debus. The Saturn V rocket that carried Apollo 11 to the moon was a direct descendant of the V-2, built by the same engineers who had built Hitler’s weapons of terror. The technology that landed Americans on the moon was born in a concentration camp.

Linda Hunt’s investigation in 1984 finally brought the truth into public view. The Justice Department’s Office of Special Investigations opened cases against several Paperclip scientists. Arthur Rudolph surrendered his citizenship. But most subjects died before facing prosecution. No successful war crimes conviction was ever obtained against a Paperclip recruit. Over ten thousand pages related to the program remained classified as of 2024.

The same pattern of government secrecy and moral compromise appears across our Declassified series – from MKUltra to the Manhattan Project’s secret cities to America’s hidden doomsday bunkers.

Arthur's Verdict

The men who put America on the moon were the same men who built Hitler's deadliest weapons. The government knew. They recruited them anyway.

Frequently Asked Questions

Operation Paperclip was a secret United States intelligence program that recruited more than 1,600 German scientists, engineers, and technicians from Nazi Germany after World War Two. The program ran from 1945 to 1959. American intelligence officers fabricated new identities and sanitized the backgrounds of former Nazi Party members and SS officers, directly violating President Truman's order prohibiting entry for anyone who had been an active supporter of Nazi militarism. The scientists were placed in key positions across the American military, aerospace, and intelligence agencies. The name came from the paperclips that intelligence officers attached to the files of recruits they had selected.
Wernher von Braun was a German rocket engineer who held the rank of Sturmbannführer in the SS. During World War Two, he served as technical director of the V-2 rocket program. The V-2 rockets were built at the Mittelbau-Dora concentration camp, where an estimated twenty thousand prisoners died from starvation, exhaustion, and execution. After surrendering to American forces in 1945, von Braun was brought to the United States through Operation Paperclip. His Nazi past was erased from official records. He went on to become the director of NASA's Marshall Space Flight Center and the chief architect of the Saturn V rocket that carried Apollo astronauts to the moon in 1969.
In 1984, investigative journalist Linda Hunt filed a Freedom of Information Act request with the United States government and uncovered approximately one hundred thirty thousand classified pages documenting Operation Paperclip. Her findings, first published in the Bulletin of the Atomic Scientists in October 1984, revealed the systematic falsification of Nazi scientists' backgrounds by American intelligence. The Justice Department's Office of Special Investigations subsequently launched investigations into several Paperclip recruits during the 1980s and 1990s. Arthur Rudolph, the designer of the Saturn V rocket, was stripped of his citizenship and deported in 1984. However, most subjects died before facing prosecution. Over ten thousand pages related to the program remained classified as of 2024.

The scientists who built Hitler's V-2 rockets went on to build the Saturn V that landed Americans on the moon. Does the achievement justify how they got there? Or did America choose winning the Space Race over justice for twenty thousand concentration camp victims?
