Modified "W" Class Destroyer (1918)

A total of sixteen destroyers of the Modified "W" Class were completed soon after the war, though many more were cancelled. The ships were a variation of the "W" class destroyers completed in some time earlier. The design of the stern was different, and there were changes in the boiler room arrangement to improve watertightness which made the second funnel larger than the first, but the big change was that the 4-in guns long common on Royal Navy destroyers were now landed in favor of 4.7-in weapons.

Armament

Other Guns

In 1918, it was ordered that the Scott class flotilla leaders and destroyers of "V" and "W" classes should have range and deflection receivers for their 3-in H.A. guns and fire gongs worked off the firing key used for the ships' L.A. weaponry.

Fire Control

Directors

Firing Circuits

Training and Slewing Circuits

In 1917, it was approved that the "V" class and later destroyers should all receive installations of the British Destroyer Director Firing System. These ships were likely delivered with directors in place.^{[Citation needed]}

In 1918, it was ordered that those destroyers with director installations were to additionally receive:

• a voice pipe from T.S. to director
• a fire gong at director worked from existing push in T.S.
• a fire gong push on fore bridge to be added, wired in parallel to that in the T.S.
• the repeat receivers on the fore bridge were to be positioned so as to be visible to the director sightsetter.
