Most frustrating to Thach's goblin killers is the sea's own natural cacophony. Antisubmarine-warfare hands are trained to differentiate the sound of a sub from that of a destroyer or a rowboat. But they must also learn that a school of shrimp sounds like fish frying, that sea robins cluck, that the white whale creaks like the lid on Davy Jones's locker, that the eel makes a zizz like water on a hot stove, and the whistling, jocular porpoise makes enough noise to give any sonarman a headache. Most deceptive of all for Thach...
...Exercise. Airman Thach himself needed training in submarine warfare. He took a short course at Norfolk's ASW Tactical School, whizzed through studies in sound detection in New London, dropped anchor at Key West's weapons-testing center, climbed aboard every nuclear submarine in the Atlantic, visited destroyers, jawed with officers and bluejackets. Next he ordered a "cross-pollination" program, sent his aviators aboard submarines, his sub skippers into helicopters, his destroyer men into 52Fs. He put airplane pilots at the helms of submarines to help work out tactical underwater maneuvers...
...Manhattan to defuse the international time bombs threatening the peace of the Middle East. Last week, after eight days of palaver, the Assembly brought forth its own novel method of bomb disposal. The technique: wrap the infernal device in verbal cotton wool-this deadens that unpleasant ticking sound-and tiptoe quickly away...
...physical, biological, geological and chemical characteristics." Trieste's real mission may be more urgent: submarine warfare is clearly going deep, deep, deeper. Conventional subs now dive about 750 ft., and some advanced models are capable of 1,000 ft. One growing antisub problem is that present sound gear penetrates accurately to only about 800 ft. Another is that depth charges sink too slowly (14 ft. per second) to hit a fast sub sailing deep at high speed, and the explosion is reduced by pressure. U.S. submariners are also reportedly anxious to design a vessel capable of operating as deep...
...Trieste help? It may improve sonar gear by showing how to cut through the ocean's sound-distorting layers of temperature and noisy marine life. Already it has found life right at the bottom. Another finding: layers of different temperature form "tunnels" that carry sound waves for thousands of miles. In one, an exploding 4-lb. charge of dynamite can be heard from San Diego to Hawaii...
