Fort Duquesne was built by West Coast Shipbuilders in Vancouver as SS Queensborough Park for the Canadian Merchant Navy as part of the Canadian government's Park ship program.[1] The vessel was a "Victory" type cargo ship.[1] Before she was completed, the vessel was transferred to the British Ministry of War Transport.[1]
