At the end of the war, the vessel was allocated to the Home Fleet but was given a reduced crew in 1919 as there was no longer the need for as many active ships in the navy.

The destroyer subsequently helped in the searches following the loss of the submarines H47 and M2, as well as rescuing 10 members of the crew of the steamer Ioannois Fafalios, sunk after colliding with the freighter Bacchus.

[1] The design was generally similar to the preceding M class, but differed in having geared steam turbines, the aft gun mounted on a raised platform and minor changes to improve seakeeping.

A total of 296 long tons (301 t) of fuel oil was carried which gave a design range of 3,450 nautical miles (6,390 km; 3,970 mi) at 15 knots (28 km/h; 17 mph).

[4] Armament consisted of three single 4 in (102 mm) Mk IV guns on the ship's centreline, with one on the forecastle, one aft on a raised platform and one between the second and third funnels.

[3] Laid down by Harland & Wolff at their shipyard in Govan on 27 August 1915, Salmon was launched on 7 October the following year and completed on 20 December.

[9] During that time, the German submarine tactics had changed from using gunfire, so that, by April, over half of the vessels sunk had been hit by torpedoes.

[17] On 5 December 1921, the destroyer carried the Private Secretary to the Prime Minister, Geoffrey Shakespeare, to Belfast to negotiate the peace that led to the Anglo-Irish Treaty.

[21] On 3 April 1928, the four destroyers of the Portland Anti-Submarine Flotilla, including Salmon, undertook a display of speed and dexterity, using depth charges to create a spectacle, for Amanullah Khan, the King of Afghanistan, while he was on a state visit.

[22] On 5 May, Salmon rescued 10 crew members of the Greek steamer Ioannois Fafalios which had sunk after colliding with the stores freighter Bacchus.
