===Wartime modifications===
Beginning in May 1940, the after bank of torpedo tubes was removed and replaced with a [[QF 3 inch 20 cwt gun|QF 12-pounder 20-cwt anti-aircraft gun]],<ref group=Note>"Cwt" is the abbreviation for [[hundredweight]], 20 cwt referring to the weight of the gun.</ref> the after mast and funnel being cut down to improve the gun's field of fire. Four to eight [[Oerlikon 20 mm cannon|QF 20&nbsp;mm Oerlikon]] [[Autocannon|cannon]]s were added to the surviving ships, usually replacing the .50-calibre machine gun mounts between the funnels. One pair of these was added to the bridge wings and the other pair was mounted [[wikt:abreast|abreast]] the [[searchlight]] platform.<ref name=l1/> Early in the war, depth charge stowage increased to 38.<ref>Friedman, pp. 236–37</ref> By 1943, all the surviving ships, except {{HMS|Fury|H76|2}} had the 'Y' gun on the [[Deck (ship)|quarterdeck]] removed to allow for additional depth charge stowage and two additional depth charge throwers. The 12-pounder was removed to allow for the installation of a [[Huff-Duff]] [[radio direction finder]] on a short [[mainmast]] and for more depth charges. All of the survivors, except perhaps for {{HMS|Echo|H23|2}}, had 'A' or 'B' gun replaced by a [[Hedgehog (weapon)|Hedgehog]] anti-submarine [[spigot mortar]], and their director-control tower and rangefinder above the bridge removed in exchange for a [[Type 271 radar|Type 271]] target-indication [[radar]], {{HMS|Fame|H78|2}} had her 'A' gun reinstalled by 1944. A [[Type 286 radar|Type 286]] short-range, surface-search radar, adapted from the [[Royal Air Force]]'s ASV radar, was also added. The early models, however, could only scan directly forward and had to be aimed by turning the entire ship.  {{HMS|Express|H61|2}}'s modifications differed somewhat in that 'B' gun was replaced by a twin-gun [[QF 6-pounder Hotchkiss]] mount and a split Hedgehog installation. In addition, she retained her 12-pounder gun, but her remaining torpedo tubes were removed.<ref name=l1/>
