In 1907 it was decided that all the Rivers (except Test and Stour, which were not yet in hand) would be among 42 destroyers (primarily Tribals and Rivers) and Swift to receive radio equipment fixed to the "D" tune of 700 feet wavelength for transmission and with a Mark II receiver tunable to 8,300 feet. One P.O. telegraphist would be allowed each ship. All ships had their mast fitted with a 12 foot yard 60 feet above the water and received the aft end of the aerial by the awning station, but the placement of the wireless office varied as follows. Liffey, Foyle, Arun, Ouse, Itchen, Moy, Blackwater, Chelmer, Colne, Jed, Kennet, Wear, Rother, Ure, Exe, Swale, Erne, Ettrick, Dee, Cherwell, Nith, Ness, Waveney, Doon, Boyne, Kale, Derwent and Eden had the office on the bridge with an extended chart house, whereas Welland, Gala, Ribble, Teviot, Garry and Usk had their offices on the upper deck between the mast and fore funnel.
The short wavelength meant the sets worked less well during the day than at night, and tests between Portsmouth and Portland showed strength 8 by night and 6 by day. Practical tests with Usk showed the following strengths over 50 miles of water:
|Signal Strengths from/to|
Originally carried the same armament dating back to the "B" class:
- One 12-pdr 12 cwt on a P. I mounting. The gun recoiled 12 inches and the mounting and its sights were capable of 30 degree elevations (9500 yards).
- Five Q.F. 6-pdr on Mark I* mountings recoiling 5 inches. The mounting could elevate 30 degrees, but the sight only 25 degrees (4000 yards). By 1920, two 6-pdrs had been removed.
From 1906, the 6-pdrs had been replaced by three 12-pdr 8 cwt guns. An order from March 1913 that special sights provided for these be returned indicates that the 8cwt guns were on G. I* mountings and had telescopic sights. Sometime during the war, some of the ships landed two of these 8 cwt weapons to offset the weight of depth charges.
In late-1913, the 12-pdr mountings were equipped with percussion firing gear.
By 1920, the 29 remaining ships had also been fitted with a Q.F. 12-pdr 8 cwt on a converted H.A. mounting.
- two single 18-in tubes, on the centreline.
Arrangements were made in 1909 to equip the ships with chocks (for 21-inch Mark I or Mark II torpedoes, curiously) or fixed loading trays (for 18-inch torpedoes) for deck storage of a spare torpedo per tube in time of war. This may have forecast hopes to switch to 21-inch torpedoes, as Waveney was testing an experimental 21-inch tube (weight: 2744 pounds), derrick and winch that same year before transferring the equipment to Rocket, the then-tender to Vernon.
During the war, along with "A" to D" classes, these ships were given depth charges. A pair of 12-pdr 8cwt guns were landed in some cases to maintain stability.
The River class were the last British destroyers to use a single searchlight.
By 1915, at least, these ships 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.
By mid-1918, these destroyers were among several earlier classes for which "alarm circuits" were to be fitted.
In 1917, it was approved that "D" through "G" class destroyers should receive firing gongs at the tubes, operated from the bridge.
