During the Norwegian Campaign HMS Arab survived 31 bombing attacks in five days while serving in the Namsos area. On one occasion during this period her CO Lt. Stannard and two of his crew tackled for two hours a fire on the jetty caused by a bomb igniting ammunition. Part of the jetty was saved, which proved invaluable at the subsequent evacuation. Later feats included the destruction of a Nazi bomber whose pilot, thinking that he had HMS Arab at his mercy, ordered that she be steered into captivity.

Returned to her owner in November 1945.
Renamed Loch Seaforth in 1947.
Scrapped at Ghent, Belgium in 1963.
