HMS Seawolf was an S-class destroyer that served with the Royal Navy and, in 1922, was commanded by the future Admiral of the Fleet, John Tovey.

Subsequently deployed to Ireland, the vessel carried some of the bodies of the victims of Bloody Sunday to their funerals in 1920 and, in 1924, rescued the passengers and crew of the steamship Asian that had sunk in a storm near Queenstown.

After the London Naval Treaty of 1930 restricted the tonnage of destroyers operated by the Navy, Seawolf was retired and, in 1931, was sold to be broken up.

A full load of 301 long tons (306 t) of fuel oil was carried, which gave a design range of 2,750 nautical miles (5,090 km; 3,160 mi) at 15 knots (28 km/h; 17 mph).

[8] The ship was designed to mount two additional 18 in (457 mm) torpedo tubes either side of the superstructure but this required the forecastle plating to be cut away, causing excess water to come aboard at sea, so they were removed.

[10] One of nine of the class to be built by the shipyard,Seawolf was laid down on 30 April 1918 by John Brown & Company in Clydebank with the yard number 480, launched on 2 November shortly before the Armistice that ended the First World War and completed on 28 January the following year.

[18] On 28 December, the destroyer, along with sister ships Sardonyx and Tenedos, left the capital of Tallinn and sailed home, arriving in Rosyth on 4 January the following year.

[27] On 17 September 1924, while based at Queenstown, Seawolf rescued the passengers and crew of the Leyland Line steamship Asian that went down in a storm.
