"Opportune" performed missions of international goodwill and mercy on her first European cruise (April–June 1960). She escorted two Iranian ships to the entrance of the Mediterranean, then sailed directly to Agadir, Morocco, where she delivered 50 tons of clothing donated by the Navy for victims of the recent earthquake. Princess Lasla Aisha, sister of the King of Morocco, came on board to thank "Opportune" for her aid.
