Taken over by the Admiralty and completed as a Landing Ship Gantry carrying 15 LCMs with accommodation for 150 military personnel. Took part in the North African, Italian, and Far East landings.
In August 1943, Captain S.T. Dunster was awarded the OBE. The citation read:
"The ship [RFA Ennerdale] played a vital part in carrying oil and petrol to forces operating off the coast of North Africa and was the focus of sustained and heavy air attacks. So skillfully was she handled by her Master and so efficient was her barrage that she sustained no damage, and performed invaluable work. In addition to this service, her Master did well in two Malta Convoys earlier in the war. His courage and resource have been unfailing."
In December 1945 she was damaged by a mine at Port Swettenham in Malaya, and returned to the UK for repair. After the war she resumed freighting duties as a tanker.
