SMS G102[a][b] was a G101-class large torpedo boat (Großes Torpedoboot) operated by Imperial German Navy during the First World War.

The ship was ordered for the Argentine Navy from the German shipyard Germaniawerft as the San Luis, but was still under construction at the start of the war and was seized by Germany.

G102 was interned at Scapa Flow after the war, and was present at the Scuttling of the German fleet on 21 June 1919, but did not sink, and was allocated to the United States under the Treaty of Versailles.

In 1912, the Argentine Navy ordered four large destroyers, (Santiago, San Luis, Santa Fé and Tucuman) from the German shipyard Germaniawerft as a replacement for British-built ships that had been built for Argentina but had been sold to Greece before completion (as the Aetos-class).

[8] On 16 August 1915, the 2nd Torpedo Flotilla was ordered to carry out a patrol off Horns Rev to search for a reported British submarine and armed trawlers.

[26] On 14 February 1918, the 2nd Flotilla, including G102, set out from Germany to attack the Dover Barrage, an anti-submarine barrier consisting of a minefield patrolled by trawlers and other small craft.

In order to avoid alerting the British defences, the German force would attack without stopping at Flanders, refuelling on the return journey.

[34] Following the end of the First World War, G102, along with much of Germany's remaining fleet, was interned at Scapa Flow in accordance with the terms of the Armistice of 11 November 1918.

[3][35] On 21 June 1919, the German fleet interned at Scapa scuttled itself, but several of the ships, including G102 did not sink, either being beached by British forces or drifting ashore when mooring cables were cut.

[3][36][37] G102 was refloated and allocated to the United States under the Treaty of Versailles as a "Propaganda ship", which could be used for a short period of time for experimental purposes or as a target.
