Project: Whisper is a top secret research and development project designed by the Nazis in the game Wolfenstein: The New Order.
Project: Whisper is the name given to the development of an experimental helicopter designed to be quiet in flight and undetectable by means of radar. The helicopter is also designed to be multirole, able to transport or pack weapons for all out attack. They were successful in creating three VTOL-like helicopters that were capable of such a thing. The three working prototypes were placed within the London Nautica and were kept under heavy guard by means of both Soldiers and Guard Robots of the Nazi regime.
