Ship project history: War on Atlantic demanded the increasing number of escorts. For reduction of terms of building the design of "River" class frigate has been recycled under a section method of building. Now shipbuilding yards only assembled the ships from already ready sections in weight to several tens the tons made at the inland plants. At designing the basic thrust became on adaptability to manufacture of production, 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 in 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 "River", these ships first of all formed as anti-submarine, but them it was possible to equip with more perfect Squid ASW rocket launcher. Air defence possibilities have simultaneously considerably improved also by installing of the quadruple 40mm pom-pom.

Only 28 ships were completed from 110 ordered frigates of "Loch" class on an 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.
