There was a mix of Admiralty design vessels (39) and a diverse set of builder's specials (12 ships), and a refined Admiralty design (11 ships) that is sometimes referred to as the '''Modified "R" Class'''.<ref>Conway's. pp. 76-77, 79-80.</ref>

There was a mix of Admiralty design vessels (39) and a diverse set of builder's specials (12 ships).  While 62 ships were planned, feedback on the performance of the early units led to the final 11 being adapted into the [[Modified "R" Class Destroyer (1916)|Modified "R" class]].{{Conways1906|pp. 76-77, 79-80}}

In 1916, it was stated that "new destroyers" have two 26.25 kw dynamos arranged in parallel.<ref>''Annual Report of the Torpedo School', 1916', p. 120.</ref> It is likely that this applied to this class.

The eleven modified "R" class ships had three 4-in Q.F.

By 1915, at least, these ships also had fixed voice pipes installed between decks with the last lengths being flexible (one voice pipe for gunnery, one for torpedoes) fitted between bridge and guns, torpedo tubes, and searchlights.  A third voicepipe, entirely flexible, ran from bridge to the forward gun.<ref>''Manual of Gunnery, Vol. III., 1915.'', p. 150.</ref>

By November 1918, those ships operating with the [[Twentieth Destroyer Flotilla (Royal Navy)|Twentieth Destroyer Flotillas]], ''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.<ref>Admiralty.

Revision as of 12:35, 21 September 2012

A total of 51 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). While 62 ships were planned, feedback on the performance of the early units led to the final 11 being adapted into the Modified "R" class.[1]

Performance

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

Admiralty R

Knots Tons / hour Endurance
(hours)
radius (nm)
14 1.7 170 2,380
16 2.0 142 2,272
18 2.6 110 1,980
20 3.4 80 1,600
22 4.5 63 1,386
24 5.5 50 1,200
26 7.2 40 960
28 9.0 30 840
30 11.5 24 720

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

Three 4-in Q.F. Mark IV guns on P. IX mountings, as in the preceding "M" class destroyers.

Other Guns

By 1920, some or all had one 2-pdr pom-pom for air defence.[4]

Torpedoes

Other Weapons

Fire Control

Alterations

By November 1918, those ships operating with the Twentieth Destroyer Flotillas, Telemachus, Tarpon and {UK-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.[5]
