 Kent was built by Chatham Dockyard and laid down on 15 November 1924. She was launched on 16 March 1926 and commissioned 25 June 1928. The ship was assigned to the 5th Cruiser Squadron on the China Station and spent the bulk of the interbellum period there. In 1929 – 30 she received a High-Angle Control System, used to direct her anti-aircraft guns, and an aircraft catapult was also fitted. Her AA armament was reinforced by the addition of two single 4-inch guns abreast the forward funnel in 1932 – 33. Two quadruple Vickers .50-calibre (12.7 mm) Mark III machine guns were added in 1934.
