The seven 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.[1] It is fairly likely that this applied to this earlier class.
Armament
Guns
Four 4-in QF Mark IV guns on P IX mountings.[2]
Torpedoes
Two double revolving 21-in torpedo mounts.[3]
Fire Control
By the end of 1915, at least, the ships had or were to be provided a range and order data system like that 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.
Rangefinders
Evershed Bearing Indicators
Gunnery Control
