Design features

The S class introduced the CP (central pivot) Mark XXII mounting for the QF Mark IX 4.7 in guns. This new mounting had a shield with a sharply raked front, to allow increased elevation (to 55 degrees), contrasting noticeably with the vertical front of the previous CP Mark XVIII, and easily differentiated the S class onwards from their immediate predecessors. Savage was the exception in this respect, being fitted with four 4.5 in guns; a twin mounting forward and two singles aft. These ships used the Fuze Keeping Clock HA Fire Control Computer.[1]

The quadruple mounting Mark VII for the QF 2-pounder pom-poms was replaced by the twin mounting Mark IV for the 40 mm Bofors gun. Known as the "Hazemeyer" (or "Haslemere"), this advanced mounting was tri-axially stabilised in order that a target could be kept in the sights on the pitching deck of a destroyer and was fitted with an analog fire control computer and Radar Type 282, a metric range-finding set. The Hazemeyer design had been brought to Britain by the Dutch minelayer Willem van der Zaan that had escaped from the German occupation in May 1940.

The T class also was the first class to replace pole or tripod foremasts with lattice masts, which continued in subsequent War Emergency Flotillas.
