Article Title and/or Image Caption (Dublin Core): Will Submarine Superdreadnought of the Future Sweep the Seas with 12-Inch Guns?; Caption 1: The undersea superdreadnought is in its first stages of development. Japan is constructing a number of submarines of 7500 tons displacement, equipped with four 7.5-inch and 5.5-inch guns. Diesel engines will drive these fighting ships at a speed of twenty-one knots; Caption 2: The efficiency of the torpedo is still an uncertainly, as German learned. The smaller submarine is giving place to the heavily armored sub-surface battleship, of which the British "M" type is the first experimental example, designed to "mop up" disabled ships
