Ship project history: In the beginning of 1944 a part of "Loch" class frigates was reoriented on the decision of air defence tasks for operations on Pacific ocean where the basic threat emanated not from submarines but from aircraft, their anti-submarine potential was thus stored (the truth, in a little deadened kind). The basic weapon of new frigates which have replaced "Loch" names ("Lake" by Scottish) by "Bays", were two twin 102mm DP mounts with radar-tracking aiming (they were removed from outdated WAIR program destroyers and damaged "Hunt" class escort destroyers).

26 units were scheduled to re-equipment, 21 was completed. 4 More were completed as survey vessels, works on one more have suspended.

Modernizations: None
