Lewis gun
Main armament for a V-class destroyer consisted of four QF Mark V guns. This was supplemented by a QF 2-pounder gun (with a second installed in January 1942), two twin Lewis gun mountings, a single Lewis gun (later replaced by a 4-barrel Vickers .303 gun), and two torpedo tube sets (initially 3-tube, later replaced by 4-tube sets). Four depth charge chutes were fitted during construction, with two depth charge throwers installed later; the destroyer could carry up to 50 charges.
