In June 1942, seven months after the United States had entered World War II, Pan Royal made two roundtrips in transatlantic convoys between Boston and the United Kingdom via Halifax.
While in the UK during her second visit, the ship had called at Belfast Lough, Barry, and Milford Haven before returning to New York in October.
In mid November, Pan Royal sailed from Hampton Roads, Virginia, to Casablanca, and returned in mid-January 1943.

On 7 February 1943, Pan Royal departed Hampton Roads in Convoy UGS-5 for North Africa.
Two days out, Pan Royal was accidentally rammed by both the Norwegian cargo ship Evita and the American Liberty ship George Davis.
Pan Royal sank at position 36°40′N 67°20′W with the loss of eight men.
Her 54 survivors were rescued by US Navy destroyer USS Boyle (DD-600).
