The S and T class was a class of sixteen destroyers of the Royal Navy launched in 1942–1943. They were built as two flotillas, known as the 5th and 6th Emergency Flotilla, and they served as fleet and convoy escorts in World War II.

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.

[ru] Эскадренные миноносцы типов S и T

Эскадренные миноносцы типов «S» и «T» — тип эскадренных миноносцев, состоявший на вооружении Королевских ВМС Великобритании в период Второй мировой войны. Заказ на 16 кораблей типов «S» и «T» был выдан в 1941 году в рамках «Чрезвычайной военной программы» (поэтому корабли этого типа называли «5-я и 6-я чрезвычайные флотилии»), два из них ещё в ходе постройки были переданы ВМФ Норвегии. Вошедшие в строй в 1943—1944 годах эсминцы участвовали в боевых действиях в Арктике, Средиземном море и Тихом океане (в том числе боях у Нордкапа и в Малаккском проливе), два корабля были потеряны — «Свифт» и норвежский «Свеннер». После войны три эсминца типа S были переданы ВМС Нидерландов. Все 8 представителей типа T в 1950-х годах прошли конверсию в противолодочные фрегаты типов 15 и 16, списаны и проданы на слом в 1960-е, как и большинство эсминцев типа S.
