    Hi all

    For ships and/or submarines operating in hostile waters during WW2, how dangerous was it sending radio messages back to your HQ. By using triangulation of a radio signal from two, or more different listening posts, the transmitters’ location could be determined. But how dangerous was this, how quickly could a ship/submarine be located, enabling local forces to track it down and destroy.

    IMO, it was suicidal. Hunter Killer group would be dispatched and generally sank the sub.

    Didn't Luthjens send a 30 minute message to Hitler when he thought the Bismarck was doomed. At least he doomed the ship himself..
