...machine's first tests was to distinguish sonar signals bounced off a submarine from those bounced off a porpoise, the ocean floor, or schools of fish. Even an ordinary computer could solve the same problem, but only after a tedious programing telling it exactly how. The Cybertron was merely fed a variety of sounds -several thousand-and after some diligent work by Witt on the goof button, it soon learned to discriminate infallibly. The Cybertron responds by flashing lights on its console, can give not only "yes" (the submarine) and "no" (the porpoise) answers but a broad variety...

...remember the breeze-cooled side on Indiabound ships. Acronyms first picked up speed in World War I with such coinages as Anzac, for Australia and New Zealand Army Corps, AWOL, for absent without official leave, and asdic (Allied Submarine Detection Investigation Committee), which eventually led to the development of sonar (sound navigation ranging...

...Toned Sonar. Biggest change of all is in the business of sub detection. The search for hidden subs still depends largely on sonar (underwater sound waves), but there has been an important switch: low-power, high-frequency sound has been replaced by low-frequency waves of enormous power...

Sound with the pitch of low piano notes travels much farther than the high-pitched beeps of early sonar. But generating enough such noise under water is a large problem. The Navy's latest shipboard sonar weighs 30 tons and consumes 1,600 times as much power as the standard postwar sonar. The listening apparatus is trickier because the long, slow waves that echo from targets require computers to interpret them correctly. But the detection problem is considered licked, since the new equipment has many times the range of earlier sonars-enough for catching nukes under most combat conditions...

Ocean of Sound. The most ambitious A.S.W. project now under consideration is Artemis, an extremely powerful sonar system that may-so its tests indicate-fill a whole ocean with searching sound and spot anything sizable that is moving in the water. Artemis grew out of a 1951 suggestion by Harvard Physicist Frederick V. Hunt, who convinced Navy A.S.W. experts that submarines could be detected at great distances only by unheard-of volumes of low-pitched sound...
