==Director FIring==

==Fire Control==
The first installations of the [[British Destroyer Director Firing System]] were being effected in May 1918.{{UKTH23|p. 12}}
+
 
 +
===Mid-1916 Outfit===
 +
Experiments from February with two Grand Fleet destroyers employing [[Dumaresq|dumaresqs]] and [[Vickers Range Clock]]s and voicepipes showed definite advantages over ships using unaided spotting and voicepipes, even when the crews had no special training in the new equipment.  Tests were also conducted to find a rangefinder suitable to the lively and cramped platform that destroyers provided.  This led to an order on 3 April, 1916 that each T.B.D. of [["M" Class Destroyer (1914)|"M" class]] and later should be equipped with:{{UKTH23|p. 31}}{{UKProgressInNavalGunnery1914-1918|p. 35}}
 +
* one [[Waymouth-Cooke Rangefinder|Waymouth-Cooke sextant rangefinder]]
 +
* one [[Vickers Range Clock]]
 +
* one Dumaresq
 +
* range and deflection receivers at each gun
 +
 
 +
Two ratings, trained before coming aboard, were added to the crew to work the equipment.  The clocks and rangefinders were issued in the following three months, and the dumaresqs a few months later.  The data instruments did not become available in numbers until 1917.  By mid-1917, the whole system was broadly in place in the destroyers of the Grand Fleet and in the [[Harwich Force]].{{UKTH23|pp. 31, 32}}
 +
 
 +
===Directors===
 +
The first installations of the [[British Destroyer Director Firing System]] were being effected in May 1918.{{UKTH23|p. 12}} The 1918 handbook on the destroyer directors indicates that these ships carried them.{{UKDirectorFiringDestroyers1918|p. 55}}
 +
 
 +
In 1918, it was ordered that those destroyers with director installations were to additionally receive:{{ARTS1918|p. 376. (C.I.O. 1081/18, G. 24486/15)}}
 +
* a voice pipe from {{TS}} to director
 +
* a fire gong at director worked from existing push in {{TS}}
 +
* a fire gong push on fore bridge to be added, wired in parallel to that in the {{TS}}
 +
* the repeat receivers on the fore bridge were to be positioned so as to be visible to the director sightsetter.
  
 
==Torpedo Control==
 
==Torpedo Control==
Line 514: Line 534:
  
 
The control position had a single Mark I deflection transmitter and separate order transmitters and keys for the forward and aft tubes.  Each torpedo mount had a combined receiver for these signals.{{ARTS1917|p. 211, Plate 84.  (C.I.O. 439/17.)}}

 +
 +
In 1921, it was approved that all "R" class destroyers should land their [[Torpedo Deflection Sight Mark II]]s so they could be replaced by replaced by [[Torpedo Deflection Sight Mark III]]s.{{ARTS1921|p. 137.  V.W.O. 11/21}}

Latest revision as of 11:26, 25 April 2018

A total of 62 destroyers of the "R" Class were completed in 1916-1917 as part of the War Emergency Programme.

There was a mix of Admiralty design vessels (39) and a diverse set of builder's specials (12 ships). Feedback on the performance of the early units led to the final 11 being adapted into the Modified "R" Class, which had slightly different armament, a bridge placed further aft, and an altered arrangement of boiler rooms that permitted two of the the three funnels to be trunked together.[1]

Performance

The ships' capacity for 300 tons of fuel, delivered the following endurance.[2]

The Modified "R" delivered much the same endurance. It's actually surprising that someone thought it worthwhile documenting them separately, given the variance between individual ships.

Machinery

Generators

In 1916, it was stated that "new destroyers" have two 26.25 kw dynamos arranged in parallel.[3] It is likely that this applied to this class.

Armament

4-in Guns

Modified "R" class (11 ships):

Others (51 ships):

Other Guns

By 1920, some or all had one 2-pdr pom-pom for air defence.[6]

Torpedoes

  • two double revolving 21-in torpedo tubes on the centreline

These, along with those in Fearless may have been among the first A.W. tubes built with screw plugs to permit the alteration of range and depth and perhaps gyro angle to be adjusted, the stop and charging valve to be access, and the collision head to be filled while the torpedo was in the tube.[7][8]

In 1917, at least some of these ships were using 21-in Mark II*** torpedoes and 21-in Mark II***** torpedoes.[9]

In mid-1920, it was ordered that the "R" class should use 21-in Mark II** torpedoes through 21-in Mark II***** torpedoes.[10]

Other Weapons

Fire Control

Mid-1916 Outfit

Experiments from February with two Grand Fleet destroyers employing dumaresqs and Vickers Range Clocks and voicepipes showed definite advantages over ships using unaided spotting and voicepipes, even when the crews had no special training in the new equipment. Tests were also conducted to find a rangefinder suitable to the lively and cramped platform that destroyers provided. This led to an order on 3 April, 1916 that each T.B.D. of "M" class and later should be equipped with:[11][12]

Two ratings, trained before coming aboard, were added to the crew to work the equipment. The clocks and rangefinders were issued in the following three months, and the dumaresqs a few months later. The data instruments did not become available in numbers until 1917. By mid-1917, the whole system was broadly in place in the destroyers of the Grand Fleet and in the Harwich Force.[13]

Directors

The first installations of the British Destroyer Director Firing System were being effected in May 1918.[14] The 1918 handbook on the destroyer directors indicates that these ships carried them.[15]

In 1918, it was ordered that those destroyers with director installations were to additionally receive:[16]

  • a voice pipe from T.S. to director
  • a fire gong at director worked from existing push in T.S.
  • a fire gong push on fore bridge to be added, wired in parallel to that in the T.S.
  • the repeat receivers on the fore bridge were to be positioned so as to be visible to the director sightsetter.

Torpedo Control

Electrical Torpedo Control Instruments[17]
found in most or all "R" class destroyers

A single sighting position was located high up in the centre of the bridge, thus requiring only a single set of firing pushes or keys as well as keys for operating a buzzer at the forward torpedo mount and a rattler at the aft mount.[18]

The control position had a single Mark I deflection transmitter and separate order transmitters and keys for the forward and aft tubes. Each torpedo mount had a combined receiver for these signals.[19]

In 1921, it was approved that all "R" class destroyers should land their Torpedo Deflection Sight Mark IIs so they could be replaced by replaced by Torpedo Deflection Sight Mark IIIs.[20]

Alterations

By November 1918, those ships operating with the Twentieth Destroyer Flotilla, Telemachus, Tarpon and Venturous, were fitted to carry 44 mines. The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.[21]
