Editing V and W-class destroyer (section)

===WAIR===
<!-- Linked from [[Thornycroft type leader]] -->
The '''WAIR type''' conversion supplemented the construction of {{sclass2|Hunt|destroyer|5}} and {{sclass|Black Swan|sloop|5}}-class escorts with their emphasis on [[anti-aircraft]] capabilities for east coast service (the exact meaning of 'WAIR' has fallen into obscurity; it is often capitalised suggesting an [[abbreviation]] or [[acronym]], but it is most likely derived from '''W'''-class anti-'''AIR'''craft). The [[Thornycroft type leader]] {{HMS|Wallace|1918|2}} was also given a WAIR conversion, but as a larger ship she also received a quadruple QF 2 pdr Mark VII mounting.

Converted ships were cleared to the main deck level, leaving only the funnels and after shelter deckhouse. The armament was replaced with four [[QF 4-inch naval gun Mk XVI|QF 4 inch L/45 Mark XVI guns]] in two twin mountings HA/LA Mark XIX, shipped on the fore and aft main decks. The armament was controlled by a Mark II(W) [[Rangefinding telemeter|rangefinder - director]], fitted with [[Type 285 radar]] for target ranging as soon as it became available. A new tower bridge, reminiscent of the Hunt class, was built and the metric Radar Type 286 air warning was added at the foremast head, replaced by [[Type 291 radar]] as it became available. The armament was completed by a pair of quadruple [[Vickers .50 machine gun|0.5 inch Vickers machine guns]] on a platform amidships, although sometimes single [[QF 2-pounder naval gun|QF 2 pdr Mark VIII]] were carried in lieu. These guns were generally sided, but a number of ships had them arranged ''en echelon'' to allow cross-deck fire. These light weapons proved to be generally ineffective and were replaced by the [[Oerlikon 20 mm cannon|20 mm Oerlikon gun]] as it became available, although other ships took priority and the older weapons were carried well into 1942 in some cases. Two racks and throwers for [[depth charge]]s were carried aft, principally for self-defence purposes, although ''Viceroy'' sank {{GS|U-1274||2}} off the east coast of Scotland on 16 April 1945.
