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" on Scottish language) 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with radar-tracking aiming (they were removed from outdated WAIR program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
Naval service: Surprise was disarmed in 1953 and used as Royal yacht.
