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 likely that this applied to this class.

Armament

The ships were armed as follows.[2]

4.7-in Guns

  • Five 4.7-in B.L. Mark I guns on C.P. VI mountings

These guns could elevate 30 degrees and had 24 common, 96 lyddite and 19 practice rounds per gun.

Other Guns

  • One 3-in H.A. gun on S. III mounting with 100 rounds
  • One .303-in Maxim with 5,000 rounds

Torpedoes

  • Two Triple Revolving 21-in torpedo mounts

The torpedoes were Mark II torpedo or Mark I**** torpedo.


Fire Control

Directors

Firing Circuits[3]
Training and Slewing Circuits[4]

In 1917, it was approved that all flotilla leaders except Swift and Abdiel should receive installations of the British Destroyer Director Firing System,[5] though no installations of this equipment were completed prior to 1918.[6]

The first three units were completed with directors.[7] It seems certain the last two would have, as well.[Inference]

The Small Type Training Receivers were pattern number 20 on #1, #2 and #3, whereas #4 and #5 had pattern number 21.[8]

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.[9]

Torpedo Control

Torpedo Control Circuits in Shakespeare and Spenser[10]

In 1919, it was decided that all (except it seems Broke) should each receive a Renouf Torpedo Tactical Instrument Type A.[11]

Dreyer Table

These ships had no fire control tables.[12]
