[1] The operation was designed to completely evaluate the entire V-2 rocket assembly, interrogate German personnel specialized in all phases of it, and then to test and launch missiles across the North Sea.

Auxiliary Territorial Service (ATS) Junior Commander Joan Bernard also played a role in this operation.

The Americans had already taken away most of the V2 rocket technology from the German underground Mittelwerk factory at the Mittelbau-Dora concentration camp near Nordhausen.

Many of the rockets and the hydrogen peroxide fuel used in the operation were provided by T-Force, a secretive British Army unit that had, in spring and summer 1945, searched for German military technology and scientists.
