Wake-Less Torpedoes Blasted Jap Navy -- A trial Surface run of the torpedo at the Sharon, Pa., Westinghouse plant. It breaks water some 50 yards from its starting point before splashing caused by its exit from the tube, subsides. This view is taken looking straight out from dock where torpedo was launched, the tube having been lowered into water in the- cut-away port son of the dock.Wake-less torpedoes that sped, silent and untraceable, through enemy waters played an important part in blasting the Jap Navy. Developed and built by westinghouse, these torpedoes were the first electrically- propelled projectiles of their type and were standard submarine equipment more than a year before V-J Day.
