Germany became aware of the depth charge following unsuccessful attacks on U-67 on 15 April 1916, and U-69 on 20 April 1916. [3] The only other submarines sunk by depth charge during 1916 were UC-19 and UB-29. [3] Numbers of depth charges carried per ship increased to four in June 1917, to six in August, and 30–50 by 1918.

German Naval Grid Reference (German:Gradnetzmeldeverfahren), was a system for referencing a location on a map. Introduced initially by the German Luftwaffe just before World War II , it was used widely in the German armed forces until 1943.
The cruiser submarine concept originated during the unrestricted submarine warfare campaign of 1917.Three German Type U 139 submarines and seven former merchant submarines, each armed with two 15-centimetre (5.9 in) guns, patrolled areas distant from their North Sea bases to sink Allied merchant shipping as part of an effort to end World War I by starving the United Kingdom of Great Britain ...
A German U-boat from the First World War is likely to have been sunk deliberately rather than being handed to the Allies, according to a 3D map produced by researchers.
After World War I depth charge throwers were developed, which could hurl depth charges some 100 feet (30 m) from the side of a ship, perpendicular to its direction of travel. These were a significant improvement over the old method, permitting the use of large 'patterns' of up to ten depth charges from the throwers and stern depth charge rails ...

The changes in British tactics meant that they had swiftly established a defence in depth on reverse slopes, protected by standing barrages, in dry, clear, weather with specialist counter-attack reconnaissance aircraft for the observation of German troop movements and improved contact-patrol and ground-attack operations by the RFC.
The German Navy's pre-war planning held that the British would be compelled to mount either a direct attack on the German coast to defeat the High Seas Fleet, or to put in place a close blockade. Either course of action would permit the Germans to whittle away at the numerical superiority of the Grand Fleet with submarines and torpedo boats.
