Although reportedly completed on 5 December 1917,[2] she was listed as being commissioned on 15 November 1917,[3] prior to her completion. In December 1917, she was assigned to the 13th Destroyer Flotilla[4] in the Grand Fleet.[5]
In early June 1918, Vectis conducted towing trials with the NS-class airshipN.S.3 to see if an airship which ran out of fuel or suffered a mechanical breakdown could be towed at speed by a ship at sea. Trials were successful, with Vectis reaching nearly 20 knots (37 km/h; 23 mph) with N.S.3 in tow. Before the final run, N.S.3 landed on the sea to exchange two officers from Vectis for two of her own crew.[6][7]
Vectis was among the ships which accompanied the battlecruisersHMS Hood and HMS Tiger during their visit to Scandinavian ports in June 1920. During the voyage, she and the destroyer HMS Vega tested the Royal Navy's High Speed Mine Sweep, which the British Admiralty hoped to use in the shallow waters of the Baltic in the event of a war with Bolshevik Russia (soon to become the Soviet Union). In a blow to the Admiralty's plans, both destroyers lost their minesweeping apparatus, demonstrating the High Speed Mine Sweep to be impractical in shallow water.[8]
After World War I, the United Kingdom received the passenger liner SS Bismarck from Germany in 1920 as a war reparation, and she was sold to the White Star Line, later the Cunard White Star Line, in which she served as RMS Majestic. In 1936, Cunard White Star retired Majestic and sold her to Thos. W. Ward for scrapping, but because of legal requirements imposed under the agreement transferring Majestic to the United Kingdom as a war prize, the British government instead took control of Majestic and assigned her to the Royal Navy. To pay Thos W Ward for Majestic, the Royal Navy agreed to transfer 24 old destroyers with a combined scrap value equivalent to that of Majestic to Thos. W. Ward for scrapping. Vectis was among these, and her transfer to Thos W Ward for scrapping took place on 25 August 1936. She was scrapped at Inverkeithing, Scotland.[2]
