Revision as of 15:12, 16 September 2012

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 Q.F. Mark IV guns on P. IX or C.P. III mountings.[2]

Torpedoes

Two double revolving 21-in torpedo mounts.[3]

Fire Control

Range and Order Instruments[4]

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.

The ships did not receive a director.[6]

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.[7]
