HMS Derg and her sisters HMS Kale and HMS Tay with destroyers HMS Rapid, HMS Relentless and the two Australians HMAS Norman and HMAS Quiberon were responsible for providing the A/S escort for the final leg of the passage.

In September 1945 Derg was part of the large armada of naval ships assembled at Tokyo Bay, where the official surrender of Japan was held onboard the American battleship USS Missouri.

In 1951 Derg was renamed Wessex and was used as an RNVR drill-ship, at a later stage in her life she was renamed Cambria.
