The Coracle of ancient Britain, still used in Wales.Figure 49 shows a British submarine, a sister ship of the E-11, that entered the Sea of Marmora through the Dardanelles for the purpose of destroying Turkish and German shipping. The E-11 put a torpedo right into Constantinople harbor. The Second Officer of the E-11 in relating this exploit, stated that they steered by the “Sperry” all the way in and out. His remark was that, “It never let me down.”In this exploit, and many others of a similar nature, the Gyro-Compass was used for all navigation. These extremely daring and hazardous operations would not have been possible without this instrument.A similar British submarine left Harwich on the east coast of England, and during a period of three weeks made seven patrol trips, and without once seeing the sun, finally returned to Harwich and picked up the buoy at the mouth of the harbor without the least difficulty. The navigation in this case was carried out entirely by the Gyro-Compass.Repeaters on Test.Figure 54 is a photograph of H. M. S.Lion, the flagship of Admiral Beatty in the battle of Jutland. This ship was provided with the Sperry Gyro-Compass equipment early in the war. During the Jutland engagement a fire broke out in a magazine of theLionimmediately below the two Master Compasses which were located in one compartment. It became so hot that the lead sheathing was melted off the electric cables and one of the Gyro-Compasses was heated until its parts fused. Notwithstanding this same heat the other compass functioned throughout the entire action. Of the ships engaged in the battle of Jutland practically all except the destroyers were equipped with the Gyro-Compass. Every one of them performed perfectly throughout the action except in the case of theLionon which one was destroyed by fire.Hundreds of Sperry Gyro-Compasses are veterans of many battles and encounters under heavy gunfire and adverse conditions.
