Editing E and F-class destroyer (section)

===Flotilla leaders===
For the first time since the [[A-class destroyer (1929)|A class]] of the 1927 programme, the [[flotilla leader]]s were built to an enlarged design, being lengthened to incorporate an additional QF 4.7-inch gun between the funnels. The lengthened design resulted in a three [[Boiler room (ship)|boiler room]] layout to enhance water-tight integrity. The leaders were not fitted for minesweeping or minelaying.<ref>Whitley, p. 105</ref> They displaced {{convert|1475|-|1495|LT|t}} at standard load and {{convert|2010|-|2050|LT|t}} at deep load. The ships had an overall length of {{convert|343|ft|m|1}}, a beam of {{convert|33|ft|9|in|m|1}} and a draught of {{convert|12|ft|6|in|m|1}}.<ref name=l0/> The ships carried a total of 175 personnel which included the staff of the [[Captain (D)]], commanding officer of the flotilla.<ref>Whitley, pp. 97, 105</ref> Their turbines were {{convert|2000|shp|abbr=on}} more powerful than the [[private ship]]s, which made them {{convert|0.5|kn}} faster; their propulsion machinery was otherwise identical. {{HMS|Exmouth|H02|2}} was an early wartime loss and consequently received no modifications, but {{HMS|Faulknor|H62|2}} survived the war. Her modifications differed somewhat from those of the private ships. She received a {{convert|4|in|adj=on|0}} AA gun in lieu of her aft torpedo tubes, although they were later reinstalled and the 4-inch gun replaced 'X' 4.7-inch gun. Two Oerlikons were later added on the forward part of her aft superstructure and a quadruple [[QF 2-pounder naval gun|QF two-pounder "pom-pom"]] mount replaced 'Q' gun between the funnels. Finally her rangefinder was replaced by a high-angle director fitted with a [[Type 285 radar|Type 285]] gunnery radar.<ref name=l1/>
