A total of 25 destroyers of the "V" Class were completed in 1917-1918.

Design

The bridge replaced the conventional canvas screens with steel plates to better resist heavy seas. This required the dumaresq and Line of Sight Indicator to be duplicated to port and starboard pairs. The chart table jutted out from the bridge, and a director was fitted. A panel with torpedo control instruments was also sited on the bridge.[1]

Performance

The ships' capacity for 365 tons of fuel, delivered the following endurance.[2]

Knots Tons / hour Endurance
(hours)		 radius (nm)
14 1.7 206 2,884
16 2.0 175 2,800
18 2.5 140 2,520
20 3.6 97 1,940
22 4.5 80 1,760
24 5.5 63 1,512
26 6.8 50 1,300
28 8.5 40 1,120
30 10.5 33 990

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

  • Four 4-in Q.F. Mark V guns with 30 degree elevation and 120 rounds per gun. Range and deflection receivers were Barr and Stroud, and not F.T.P..[4]

Other Guns

  • One 3-in H.A. 20 cwt Mark III with 100 rounds.[5]

Torpedoes

Two twin 21-in tubes on the centre line enjoying 50 degree arcs centered on the beam.[6]

Other Weapons

Fire Control

Instruments

Rangefinders

Directors

Firing Circuits[7]
Training and Slewing Circuits[8]

In 1917, it was approved that the "V" class and later destroyers should all receive installations of the British Destroyer Director Firing System,[9] but no installations were completed before February, 1918, but subsequent to that month, all units being completed had training systems in place upon completion and from May they had their mechanical elevating gear in place.[10][11]

Torpedo Control

Torpedo Control Circuits "V" class[12]

The "V" class had entirely electrical instruments in all vessels.

Flotilla leaders and "S", "W" and "V" class destroyers had nearly identical torpedo control facilities, with sighting positions on both sides of a bridge that had been enlarged from earlier classes with firing pushes and keys for sounding buzzers at the tubes. The order and deflection transmitters were situated centrally on a panel on the bridge, between the two sights.[13]

Alterations

A 9-foot rangefinder and two hydraulic releases for depth charges were added to the bridge at some point.[14] After the war, the twin torpedo tubes were replaced with triple mounts as in the "W" class vessels.[15]

By November 1918, those ships operating with the Twentieth Destroyer Flotilla (Vanoc, Vanquisher and Venturous) were fitted to carry 44 mines, apparently of the "H" and "M" variety. Those with the Eleventh Destroyer Flotilla were also equipped, but with "M" type sinkers: Vivacious with 40 mines and Versatile, Vittoria, Vortigern and Vancouver with 74.

Venetia and Vesper serving with the Thirteenth Destroyer Flotilla and Velox at Dover also could carry 74 "M" sinkers. The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.[16]
