Destroyer - World War I

World War I

While capital ship engagements were scarce in World War I, destroyer units were almost continually engaged in raiding and patrol actions. The first shot of the war at sea was fired on 5 August 1914 by a destroyer of the 2nd Flotilla, HMS Lance, in an engagement with the German auxiliary minelayer SS Königin Luise.

Destroyers were involved in the skirmishes that prompted the Battle of Heligoland Bight, and filled a range of roles in the Battle of Gallipoli, acting as troop’s transports and fire support vessels, as well as their fleet-screening role. Over 80 British destroyers and 60 German torpedo-boats took part in the Battle of Jutland, which involved pitched small-boat actions between the main fleets, and several foolhardy attacks by unsupported destroyers on capital ships. Jutland also concluded with a messy night action between the German High Seas Fleet and part of the British destroyer screen.

The threat evolved by World War I with the development of the submarine, or U-boat. The submarine had the potential to hide from gunfire and close underwater to fire torpedoes. Early-war destroyers had the speed and armament to intercept submarines before they submerged, either by gunfire or by ramming. Destroyers also had a shallow enough draft that torpedoes would find it difficult to hit them.

The desire to attack submarines underwater led to rapid destroyer evolution during the war, which were quickly equipped with strengthened bows for ramming, depth charges and hydrophones for identifying submarine targets. The first submarine casualty to a destroyer was the German U-19, rammed by HMS Badger on 29 October 1914. While U-19 was only damaged, the next month Garry successfully sank U-18. The first depth-charge sinking was on 4 December 1916, when UC-19 was sunk by HMS Llewellyn.

The submarine threat meant that many destroyers spent their time on anti-submarine patrol; once Germany adopted unrestricted submarine warfare in January 1917, destroyers were called on to escort merchant convoys. US Navy destroyers were among the first American units to be dispatched upon the American entry to the war, and a squadron of Japanese destroyers even joined Allied patrols in the Mediterranean. Patrol duty was far from safe; of the 67 British destroyers lost in the war, collisions accounted for 18, while 12 were wrecked.

At the end of the war the state-of-the-art was represented by the British W class.
