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.

The quadruple mounting Mark VII for the
QF 2-pounder pom-poms was replaced by the twin mounting Mark IV for the

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.
