[10][11] G193 remained part of the 2nd half-flotilla of the 1st Torpedo Boat Flotilla on the outbreak of the First World War in August 1914.

[12] On 28 August 1914, the British Harwich Force, supported by light cruisers and battlecruisers of the Grand Fleet, carried out a raid towards Heligoland with the intention of destroying patrolling German torpedo boats.

[13] The German defensive patrols around Heligoland consisted of one flotilla (the 1st Flotilla) of 12 modern torpedo boats forming an outer patrol line about 25 nautical miles (29 mi; 46 km) North and West of Heligoland, with an inner line of older torpedo boats of the 3rd Minesweeping Division at about 12 nautical miles (14 mi; 22 km).

[14] V193, at the eastern end of the patrol line, was not engaged when the British attacked, and remained on station until recalled to Heligoland by radio.

The British light cruiser Arethusa and destroyers Laurel, Laertes and Liberty were badly damaged but safely returned to base.

[16][17] From 15 to 17 December 1914, the 1st Torpedo Boat Flotilla, including G193, accompanied German battlecruisers during the Raid on Scarborough, Hartlepool and Whitby.

It was planned to enter the Gulf via the Irben Strait, defeating any Russian naval forces and mining the entrance to Moon Sound.

[d][21][22] On 25 March 1916, the British seaplane carrier Vindex, escorted by the Harwich force, launched an air attack against a Zeppelin base believed to be at Hoyer on the coast of Schleswig.

Forces of the High Seas Fleet were ordered to sea in response to the attack, and on the evening of 25 March, 18 German torpedo boats of the 1st and 6th Torpedo Boat Flotillas, including G192 were deployed in a wide front with orders to search for Medusa to the North West of Horns Rev.
