In April 1945, American forces were sweeping eastwards toward Berlin, in part advancing across territory that would eventually become part of the Soviet Occupation Zone. As they advanced, US troops uncovered major parts of the manufacturing facilities and the people associated with the engines that powered Germany’s last generation of miliary aircraft: the jet fighters and bombers.

Understandably, the engine technology involved in powering these aircraft, such as the Messerschmitt Me 262 and the Arado Ar 234, was of great interest to the Allied nations. Among the many questions that needed to be answered was whether the Germans had made important breakthroughs in their successful use of these engines.

Having made these discoveries and seizures, the American authorities needed to decide exactly what they would do with them. Would they share the bounty with the other Allies? American collaboration with the British was a fact. The French, while Allies, were, in American eyes, militarily unimportant in realizing the defeat of Nazi Germany. Sharing technology with them was not of great interest. The Soviets were far behind, but nevertheless ambitious and keen to catch up to western military capability. The Americans knew their relation to the Soviets was tense and confrontational: no sharing was likely there.

From their perspective, Hitler’s jet engineers faced not only a lost war, but the economic and intellectual realities that work in Germany would not be available. They had technical knowledge and experiences that were undeniably valuable to the Allied victors. These nations would be engaged in a new competition for control of world affairs that would be called the Cold War.

While the major technical interests were atomic bombs, guided missiles, and jet engines, it is the last of these that is explored here. What happened to the people and to the institutions they would staff? This is the story of some who found homes and work in the US and in France and some who were brutally abducted to the Soviet Union.

This is also the story of American decisions made regarding the German jet engineers and the consequences for them as people and propulsion technology for American, French, and Soviet aviation. The competitive stance between the Soviet Union and the Western Allies was one of the key elements of the Cold War that followed. It led to a brutal Russian view and execution of war reparations that elevated the Soviet Union into a powerful position to challenge the West.
