Project history

War in Atlantic demanded the increasing number of escorts. For acceleration of building the design of "River" class frigate has been modified for a section building method. Now shipbuilding yards only assembled the ships from already ready sections several tens tons weight made at the inland plants. At designing the basic thrust became on adaptability to production speed, frequently even to the detriment of other qualities. Transition to a longitudinal hull framing system and wide use of welding became basic difference from "River" class. For building simplification the unprecedented decision, forbidding to bring into the design after completing of a lead frigate any changes which could influence rates of building of the subsequent ships of a class was accepted. As well as "Rivers", these ships first of all formed as anti-submarine, and it was possible to equip them with more perfect Squid ASW rocket launcher. Air defence possibilities have simultaneously considerably improved also by installing of the quadruple 40mm pompom. Only 28 ships were completed from 110 ordered frigates of "Loch" class under original design. Besides, two more, Loch Assynt and Loch Torridon were completed as a depot ships Derby Haven and Woodbridge Haven respectively, 26 ships were completed as AA frigates of "Bay" class. The order for building of 54 more units has been cancelled.
