At the twilight of World War II, as the embers of battle subsided and the world began to reimagine its new geopolitical landscape, the United States launched an audacious covert operation. Termed “Operation Paperclip,” this classified mission sought to capitalize on the scientific prowess of Nazi Germany, aiming to bolster American defense, research, and space exploration capabilities for the decades to come.

Background and Objectives

When the dust of World War II settled, the global powers, especially the U.S. and the Soviet Union, were already eyeing the spoils of war. Both nations understood the scientific and military advantage the German technological innovations presented. Operation Paperclip, initiated in 1945, was the U.S.’s answer to this strategic opportunity.

Its primary objective was to recruit and relocate top German scientists, engineers, and technicians to the United States. In doing so, America hoped to prevent their expertise from benefiting the Soviet Union, or from contributing to any resurgence of power in post-war Germany.

Key Figures and Accomplishments

The breadth of talent acquired through Operation Paperclip was vast, but among the recruits, certain names stood out:

• Dr. Wernher von Braun: Arguably the most renowned figure of the operation, von Braun was instrumental in the development of the V-2 rocket for Nazi Germany. Once in the U.S., he became a linchpin in the development of the American space program, playing a pivotal role in the Apollo moon landings.

Through the acquired German expertise, the U.S. made significant leaps in:

1. Aerospace Technologies: These experts were foundational in shaping what would become NASA and propelling the U.S. to its eventual moon landing.
2. Missile and Defense Systems: Beyond space exploration, the German scientists were pivotal in advancing U.S. missile technology, which would prove crucial during the Cold War era.

Ethical Concerns and Controversies

The benefits of Operation Paperclip to the U.S. are undeniable. However, the program’s legacy is not without its shadows. Many of the scientists recruited had affiliations with the Nazi Party, and some were even implicated in war crimes, including conducting heinous experiments in concentration camps.

The U.S. government, in its quest for technological superiority, often chose to overlook these dark histories. These ethical oversights have, over the years, become a significant point of contention and debate.

Conclusion

Operation Paperclip underscores the intricate dance of science, ethics, and geopolitics. It is a chapter in history that presents a mix of admiration for scientific advancements and introspection on the moral lines crossed in the process.

As you delve into the declassified documents archived below, the magnitude and nuances of Operation Paperclip will unfurl, offering a more profound understanding of this pivotal moment in history.

This document is a study on the effects of the allied bombardment campaign on the German air force. It starts by giving the original composition of the German air force (mostly bombers and dive bombers). The battle of Britain and the Russian front taught them that bombers without fighter protection are very vulnerable. Item discusses fighter production, aircraft production in general, and the effects of USAAF (united states army air forces) attacks on: German tank production; the bearing industry; oil and the synthetic oil and gasoline plants (big USASF problem, as there were some 81 plants dispersed); and armament factories, motor transportation, and chemicals. Discusses the German forces committed to static defense. There are statistics on German gasoline production by month from April 1944 through January 1945.

The Alsos Mission was an organized effort by a team of British and United States military, scientific, and intelligence personnel to discover enemy scientific developments during World War II. Its chief focus was on the German nuclear energy project, but it also investigated both chemical and biological weapons and the means to deliver them.

The Alsos Mission was created following the September 1943 Allied invasion of Italy with a twofold assignment: search for personnel, records, material, and sites to evaluate the above programs and prevent their capture by the Soviet Union. It was established as part of the Manhattan Project’s mission to coordinate foreign intelligence related to enemy nuclear activity. Alsos personnel followed close behind the front lines in Italy, France, and Germany, occasionally crossing into enemy-held territory to secure valuable resources before they could be destroyed or scientists escape or fall into rival hands.

The Alsos Mission was commanded by Colonel Boris Pash, a former Manhattan Project security officer, with Samuel Goudsmit as chief scientific advisor. It was jointly staffed by the Office of Naval Intelligence (ONI), the Office of Scientific Research and Development (OSRD), the Manhattan Project, and Army Intelligence (G-2), with field assistance from combat engineers assigned to specific task forces.

Alsos teams were successful in locating and removing a substantial portion of the German research effort’s surviving records and equipment. They also took most of the senior German research personnel into custody, including Otto Hahn, Max von Laue, Werner Heisenberg and Carl Friedrich von Weizsäcker.

This document had been classified since 1939, and has never seen the light of day. In fact, at the time of requesting, even the title was classified, and was unknown.  In essence, when I filed the Mandatory Declassification Review (MDR) request to the Department of Defense (DOD), I had no idea what I was going to find.

The MDR was a success, and the document was released.

The post Report of the Coast Artillery Board on Project No. 1153, Heavy Antiaircraft Gun, March 9, 1939 first appeared on The Black Vault.

Abstract:

The proposal herein outlined sets forth the exact method for control of an aircraft bomb, classified as Barrage Type, intended to be remotely flown, thence unerringly guided from a ground control position to its ultimate target. It is suggested to also consider it as an artillery supplement in the laying down of a barrage.  In several different ways it is better for long-range intensive barrage than the huge rifles of artillery. It is contemplated to employ that part of the radio spectrum between 70 and 200 megacycles or thereabouts.

This document, from 1940, was listed with no title, and has remained classified until December of 2016. I filed a Mandatory Declassification Review (MDR) for it’s release, and it was fully granted.

Aircraft and midget submarines of the Imperial Japanese Navy began a surprise attack on the U.S. under the command of Admiral Isoroku Yamamoto.

Despite long-standing assertions that this attack could have been predicted and prevented by the United States Military, the U.S. forces at Pearl Harbor appeared to be utterly unprepared, and the attack was devastating in loss of life and damage to the U.S. fleet. At 6:05 a.m. on December 7, the six Japanese carriers launched a first wave of 183 planes composed mainly of dive bombers, horizontal bombers and fighters.

The Pearl Harbor Spy

On February 21, 1942, just 76 days after the tragic attack on Pearl Harbor, Bernard Julius Otto Kuehn (pictured) was found guilty of spying and sentenced to be shot “by musketry” in Honolulu. What was a German national doing in Hawaii in the days leading up to the attack? What exactly did Kuehn do to warrant such a sentence? Here’s the story…

Bed sheets on clothes lines. Lights in dormer windows. Car headlights. A boat with a star on its sail.

Otto Kuehn had a complex system of signals all worked out. A light shining in the dormer window of his Oahu house from 9 to 10 p.m., for example, meant that U.S. aircraft carriers had sailed. A linen sheet hanging on a clothes line at his home on Lanikai beach between 10 and 11 a.m. meant the battle force had left the harbor. There were eight codes in all, used in varying combinations with the different signals.

In November 1941, Kuehn had offered to sell intelligence on U.S. warships in Hawaiian waters to the Japanese consulate in Hawaii. On December 2, he provided specific—and highly accurate—details on the fleet in writing. That same day, he gave the consulate the set of signals that could be picked up by nearby Japanese subs.

Kuehn—a member of the Nazi party—had arrived in Hawaii in 1935. By 1939, the Bureau was suspicious of him. He had questionable contacts with the Germans and Japanese. He’d lavishly entertained U.S. military officials and expressed interest in their work. He had two houses in Hawaii, lots of dough, but no real job. Investigations by the Bureau and the Army, though, never turned up definite proof of his spying.

Not until the fateful attack of December 7, 1941. Honolulu Special Agent in Charge Robert Shivers immediately began coordinating homeland security in Hawaii and tasked local police with guarding the Japanese consulate. They found its officials trying to burn reams of paper. These documents—once decoded—included a set of signals for U.S. fleet movements.

All fingers pointed at Kuehn. He had the dormer window, the sailboat, and big bank accounts. Kuehn was arrested the next day and confessed, though he denied ever sending coded signals. His sentence was commuted—50 years of hard labor instead of death “by musketry”—and he was later deported.

Today, his story reminds us how much damage espionage can do to our country. And why the FBI continues to rank counterintelligence as a top investigative priority.

Since World War II, US intelligence agencies have devised innovative ways to defeat their adversaries. In 1944, CIA’s precursor, the Office of Strategic Services (OSS), created the Simple Sabotage Field Manual.

This classified booklet described ways to sabotage the US’ World War II enemies. The OSS Director William J. Donovan recommended that the sabotage guidance be declassified and distributed to citizens of enemy states via pamphlets and targeted broadcasts.

Surprisingly Relevant Sabotage Instructions

Many of the sabotage instructions guide ordinary citizens, who may not have agree with their country’s wartime policies towards the US, to destabilize their governments by taking disruptive actions.  Some of the instructions seem outdated; others remain surprisingly relevant. Together they are a reminder of how easily productivity and order can be undermined.

Here’s a list of five particularly timeless tips from the Simple Sabotage Field Manual

1. Managers and Supervisors: To lower morale and production, be pleasant to inefficient workers; give them undeserved promotions. Discriminate against efficient workers; complain unjustly about their work.
2. Employees: Work slowly. Think of ways to increase the number of movements needed to do your job: use a light hammer instead of a heavy one; try to make a small wrench do instead of a big one.
3. Organizations and Conferences: When possible, refer all matters to committees, for “further study and consideration.” Attempt to make the committees as large and bureaucratic as possible. Hold conferences when there is more critical work to be done.
4. Telephone: At office, hotel and local telephone switchboards, delay putting calls through, give out wrong numbers, cut people off “accidentally,” or forget to disconnect them so that the line cannot be used again.
5. Transportation: Make train travel as inconvenient as possible for enemy personnel. Issue two tickets for the same seat on a train in order to set up an “interesting” argument.

The post Simple Sabotage Field Manual, 1944 first appeared on The Black Vault.

Presents a case study of one air-ground team’s experience with the theory and practice of tactical air power employed by General George Patton during the climactic Word War 2 campaigns against the forces of Nazi Germany.

As Richard P. Hallion wrote in the foreword:

This insightful work by David N. Spires holds many lessons in tactical air-ground operations. Despite peacetime rivalries in the drafting of service doctrine, in World War II the immense pressures of wartime drove army and air commanders to cooperate in the effective prosecution of battlefield operations. In northwest Europe during the war, the combination of the U.S. Third Army commanded by Lt. Gen. George S. Patton and the XIX Tactical Air Command led by Brig. Gen. Otto P. Weyland proved to be the most effective allied air-ground team of World War II.

 

The great success of Patton’s drive across France, ultimately crossing the Rhine, and then racing across southern Germany, owed a great deal to Weyland’s airmen of the XIX Tactical Air Command. This deft cooperation paved the way for allied victory in Westren Europe and today remains a classic example of air-ground effectiveness.

 

It forever highlighted the importance of air-ground commanders working closely together on the battlefield. The Air Force is indebted to David N. Spires for chronicling this landmark story of air-ground cooperation.
