"Jutahy" was ordered by Brazil on 8 December 1937 from J. Samuel White, Cowes. The ship was laid down on 31 May 1938 and was purchased by the British on 5 September 1939 after the beginning of the Second World War and renamed HMS "Havelock". She was launched on 16 October and commissioned on 10 February 1940. After working up, the ship was assigned to the 9th Destroyer Flotilla of the Western Approaches Command. "Havelock" was detached to Home Fleet during the Norwegian Campaign and supported the Allied landings on 12–13 May at Bjerkvik during the Battle of Narvik. During the initial stages of this battle, she mounted a French mortar battery on her forecastle. She continued to provide fire support during the battle for the rest of the month. During the nights of 30 and 31 May, the ship helped to evacuate troops from Bodø to Harstad and Borkenes to await further evacuation. "Havelock" was one of the ships that escorted the troop ships evacuating the troops from the Narvik area on 7 and 8 June. She was commanded by Capt. E. Barry Stevens, DSC.
