An American project to bring former Nazi scientists to the United States after World War II, particularly those involved in the development of the V-2 rocket, including Wernher Von Braun. This was despite the fact that U.S law explicitly prohibited former Nazi officials from immigrating into America.

By 1955 more than 760 Geman scientists (the total number of people was 1600 including dependents) had been granted U.S citizenship and had their records purged of any trace of their Nazi past, including membership of the Nazi party, their use of slave labour and the fact that some of them had experimented on humans in the concentration camps.

Many worked initally on the Manhattan Project and went on to join various parts of the US space/missile program including NASA. The earliest batches being based at The White Sands Missile Ground.
