Scientists are reportedly developing a way of sending covert audio signals underwater without detection. They claim the signals will be disguised as whale song and edited with a coding system to produce the altered whale sounds.
The messages are designed to be indistinguishable from the regular background noise of the ocean.Whale song is automatically filtered out by ships and submarines and secret messages will therefore be camouflaged and go undetected, the Chinese scientists claim...
Notice how it is always supposedly the 'Chinese' or 'Russians' that are developing these technologies. No one mentions our allies.
