"W" Class Destroyer (1917)

Twenty-one destroyers of the "W" Class were completed in 1917-1918. They were essentially the same design as the "V" class, but incorporated the triple torpedo tube mounts that had not been ready in time for the "V"s.

Late in the war, an additional order was placed for a large number of Modified "W" class destroyers, most of which were cancelled.

Torpedo Control

Torpedo Control Circuits in Flotilla Leaders and "S", "W" and "V" class T.B.D.s^[3]

Torpedo Control Circuits in Later Flotilla Leaders and "W" class T.B.D.s^[5]

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.^[6]

These ships were also equipped with Chadburn's Torpedo Telegraphs for orders and deflection and battery-worked electrical firing and firing gongs.^[7]

Alterations

By November 1918, Warwick and Whirlwind were operating out of Dover and were equipped to carry 74 "M" type sinker mines. The torpedo tubes and guns removed when the mines were shipped could be placed back aboard with enough notice.^[8]
