For the next 12 months, "Jacob Jones" continued her escort duty for North Atlantic convoys. Departing from either New York or Boston, Massachusetts, she sailed as convoy escort to such ports as Derry and Moville, Northern Ireland; Liverpool, Southampton and Plymouth, England; and Le Havre and Cherbourg, France. When in the United States awaiting her next convoy, she maintained her operational readiness by training exercises in waters off Maine or Long Island. When in Europe, she operated on coastal and harbor ASW patrols. In all "Jacob Jones" crossed the Atlantic 20 times, providing protection for merchant and troop convoys in the North Atlantic.
