A total of thirty six destroyers of the River Class entered service between 1904 and 1909.

They were designated the "E" class in 1912.[1] Eden, Stour and Test alone had turbine propulsion.

Armament

Guns

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).[2]
  • Five QF 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.[2]

From 1906, the 6-pdrs had been replaced by three 12-pdr 8 cwt guns.[3] Sometime during the war, some of the ships landed two of these 8 cwt weapons to offset the weight of depth charges.[4]

By 1920, the 29 remaining ships had also been fitted with a QF 12-pdr 8 cwt on a converted HA mounting.[2]

Torpedoes

Reload tray for River class.[5]

Two single 18-in tubes.

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.[6]

In 1916, the torpedo in use was the 18-in Mark VII.[7]

Other Weapons

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.[8]

Searchlights

The River class were the last British destroyers to use a single searchlight.[9]

Fire Control

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.[10]

Instruments

Rangefinders

Evershed Bearing Indicators

Gunnery Control

Control Positions

Control Groups

Directors

Torpedo Control

Some of the ships were equipped with Fore Bridge Firing Gear, either upon completion or prior to 1911.[11]
