Attack on Imperial Japanese Navy submarine I-52:
These are two wires recording by the second aircraft sent by USS Bogue. Note that I-52 had already been sunk by the first aircraft. The propeller noise heard are from a German submarine in the area. However, the crew of the aircraft did not know this. It is interesting to hear the real rhythm of the 3 man crew working to find the target. It is also interesting how the training record above mixed the sounds from these recordings with those from the first plane’s attack for dramatic effect. These two wires survived in the collection of the NUWC Division Newport and later transferred to the US National Archives in College Park, MD. The NARA reference information is RG-38, 273, 1 and RG-38, 273, 2.
