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 1944 Derg was docked in the Selborne dry dock at Simonstown, South Africa.

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 September 1960, the frigate was broken up for scrap, at Cashmore, Newport.
