View source for Lightfoot Class Flotilla Leader (1915)

The seven [[Flotilla Leader|flotilla leaders]] of the '''''Lightfoot'' Class''' (sometimes referred to as "''Marksman'' class destroyers") were completed in 1915-16.

==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.<ref>''Annual Report of the Torpedo School, 1916'', p. 120.</ref>  It is fairly likely that this applied to this earlier class.

==Armament==

===Guns===
Four 4-in QF Mark IV guns on P IX mountings.<ref>''Technical History and Index'', Vol 4, Part 34, p. 11.</ref>

===Torpedoes===
Two double revolving 21-in torpedo mounts.<ref>''Technical History and Index'', Vol 4, Part 34, p. 11.</ref>

==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, at least, the ships had or 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 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.

==Alterations==
''Abdiel'' had long been equipped to carry mines, as she'd sown some at Horn's Reef after the [[Battle of Jutland]].  By November 1918, these were noted as being 40 "M" type sinkers.  At the same time, ''Gabriel'' was also to be equipped to carry "M" type sinkers, likely in the same number.  The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.<ref>Admiralty. ''Annual Report of the Torpedo School Mining Appendix, 1917-1918'', p. 11. Plate 7.</ref>
