In May 1924, the unit was re-equipped with the Fairey Fawn. With these aircraft, the squadron performed air-mail carrying services breaking the General Strike of 1926. In September of that year, the squadron took Hawker Horsley aircraft on complement and in November 1930 moved to Donibristle, Fife, converting to torpedo-bombing. Its revised official designation as 'No. 100 (Torpedo-Bomber) Squadron' came later, in 1933.
