UNDERSEA WARFARE.

SUBMARINE FLEET TACTICS. SWEEPING CHANGES COMING. DUE TO TELEPHONIC MARVEL, ■Dy Calfle. - Press Assjcintiou. —Co;'jri=a:.) i Received 7O a.m. 1 LONDON. March T The "Daily News'" naval correspondent says that a revolution in -übmariuo tactic?, enabling mas* attacks and the 1 launching 0; .-.vrtv of torpedoes simuli taneously. and necessitating sweeping ] changes in naval operation*, is likely to result from the American Navy's solution nf the pn ')lem of underwater communication. Preliminary te>fs have established the practicability of direct telephonic communication for two mile* under water. and there is a possibility that tliis range j may he greatly extended. 1 The system is iiascd on inaudible or [ super-sonir sound waves, which are proj jected through the water, thus enabling j the commodore of the submarine flagship to direct the movements of his flotilla witii the same eas? r.s the Admiralty manoeuvres a battleship fleet. The opinion is expressed that the invention will enable submarines to become I a legitimate weapon and thus outlive the odium they have acquired owing to their attacks on merchantmen.— I ■'Sun.")
