Article Title and/or Image Caption (Dublin Core): Sinking U-Boats with a Sub-Sea Barrage. The Isham shell, which does not ricochet, is the latest destroyer of the submarine; Caption: 1: High-angle firing makes the shell strike the water at such an angle that it will dive into the sea instead of ricocheting; Caption 2: The explosion of the Isham shell beneath the surface is regulated automatically by a time fuse set to operate at a certain degree of submergence regardless of hydrostatic pressure; Caption 3: The missiles fall all about the U-boat and form a veritable subaqueous barrage—an underwater curtain of fire
