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.[1] It is fairly likely that this applied to this earlier class.

Armament

Guns

Torpedoes

  • Two double revolving 21-in torpedo mounts[Citation needed]

In 1917, at least some of these ships were using 21-in Mark II***** torpedoes.[3]

Fire Control

Range and Order Instruments[4]

By the end of 1915, it was planned that all but Anzac at least were to be provided a range and order data system like that then being given to the "M" class destroyers and to the Faulknor class leaders.[5]

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.

Directors

Firing Circuits[6]
Training and Slewing Circuits[7]

In 1917, it was approved that all flotilla leaders except Swift and Abdiel should receive installations of the British Destroyer Director Firing System,[8] though no installations of this equipment were completed prior to 1918,[9] and though a source from 1920 indicates that the Parkers had not received theirs,[10] the 1918 handbook on the destroyer director system indicates the surviving units had them.[11]

Additionally, the Director Firing Handbook, 1917 reports that they had Small Type Training Receivers of pattern number 20 on #1, #2 and #3, and pattern number 21 on #4.[12]

Torpedo Control

In mid-1920, it was decided that all these ships except Anzac should each receive a Renouf Torpedo Tactical Instrument Type A.[13] A year later, the allocation was increased to include Anzac.[14]

Alterations

By November 1918, Seymour (only), operating with the Eleventh Destroyer Flotilla, was fitted to carry 40 "H" and "M" type mines. The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.[15]
