==Machinery==
===Generators===
In 1916, it was stated that flotilla leaders have two 26.25 kw dynamos arranged in parallel with an additional 9 kw oil-fired set for emergency use.{{ARTS1916|p. 120}}  It is fairly likely that this applied to this earlier class.

==Armament==

===Guns===
* four {{Gun|4-in Q.F. Mark IV|UK}}s on {{Mount|P. IX|UK}}.{{UKDirectorFiringDestroyers1918|p. 55}}

===Torpedoes===
* Two double revolving 21-in torpedo mounts{{CN}}

In 1917, at least some of these ships were using {{Torp|21-in Mark II*****|UK}}es.{{ARTS1917|p. 61}}

==Fire Control==
[[File:HandbookFCMClass1915_Plate14.jpg|thumb|480px|'''Range and Order Instruments'''<ref>Admiralty.  ''Handbook of Fire Control in Torpedo Boat Destroyers of "M" Class and Later and Flotilla Leaders, 1915'', Plate XIV.</ref>]]
By the end of 1915, it was planned that all but ''Anzac'' at least were to be provided a [[Barr and Stroud Mark I Fire Control Instruments#Destroyer Range and Order Instruments|range and order data system]] like that then being given to the [["M" Class Destroyer (1914)|"M" class destroyers]] and to the [[Faulknor Class Flotilla Leader (1914)|''Faulknor'' class]] leaders.<ref>Admiralty.  ''Handbook of Fire Control in Torpedo Boat Destroyers of "M" Class and Later, and Flotilla Leaders, 1915'', p. 3, Plate XIV.</ref>

The scheme placed the combined transmitter on the forebridge, and a combined receiver near the sightsetter position of each gun.  Ranges from 0 to 9900 yards in increments of 100 yards, and orders were "Independent", "Control" and "Fire" with illuminated indicators and a red indicator on the receivers to signal loss of power from the battery pack located below decks.
===Rangefinders===

By 1921, all R.N. destroyer leaders mounted a 9ft [[F.Q. 2]] on an [[M.Q. 1]], [[M.Q. 9]] or [[M.Q. 12]] mount on their fore bridge.{{HRFs1921|p. 168}}

[[File:ARTS1917Plate101.jpg|thumb|480px|'''Training and Slewing Circuits'''{{ARTS1917|Plate101}}]]
In 1917, it was approved that all flotilla leaders except {{UK-Swift}} and {{UK-Abdiel}} should receive installations of the [[British Destroyer Director Firing System]],{{ARTS1917|p. 229}} though no installations of this equipment were completed prior to 1918,{{UKProgressInNavalGunnery1914-1918|p. 37}} and though a source from 1920 indicates that the ''Parkers'' had not received theirs,{{UKTHVol4Part34|p. 17}} the 1918 handbook on the destroyer director system indicates the surviving units had them.{{UKDirectorFiringDestroyers1918|p. 55}}

Additionally, the ''Director Firing Handbook, 1917'' reports that they had [[Small Type Training Receiver]]s of pattern number 20 on #1, #2 and #3, and pattern number 21 on #4.{{DirectorH|p. 146}}

==Torpedo Control==
In 1919, it was decided that all these ships except {{UK-Anzac}} should each receive a [[Renouf Torpedo Tactical Instrument Type A]].{{ARTS1919|p. 119}}  A year later, the allocation was increased to include ''Anzac''.{{ARTS1920|pp. 90-1}}

==Alterations==
By November 1918, ''Seymour'' (only), operating with the [[Eleventh Destroyer Flotilla (Royal Navy)|Eleventh Destroyer Flotilla]], was fitted to carry forty "H" and "M" type mines.  The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.<ref>Admiralty.
