The depth-charge throwers were removed in 1936 and more 200-kilogram depth charges were carried in their place. The ship's 13.2-millimeter machineguns were repositioned in front of the bridge in early 1939. The four single 37-millimeter mounts aboard Vauquelin were replaced by a pair of twin mounts in May 1940. The Navy reconsidered its anti-submarine warfare tactics after the war began in September and reinstated the pair of depth-charge throwers, although these were an older model than the one previously installed. Vauquelin received hers in June 1940Jordan & Moulin 2015, pp. 123–127 and she was fitted with a British Alpha 128 ASDIC system later in December.Whitley, p. 41 A pair of Browning 13.2-millimeter AA machineguns were installed abaft the mainmast in late 1940–early 1941. During the ship's 6 August – 7 September anti-aircraft refit, the mainmast was replaced by a platform for the two 37-millimeter twin-gun mounts and a single Browning, the Hotchkiss machine guns were moved to new platforms between the funnels and their former positions were occupied by new Brownings.Jordan & Moulin 2015, pp. 125–128
