"Preble"s mission supported the United States' long-standing partnership with the maritime nations of Micronesia, Oceania, and the Marshall Islands, with the focus on IUU fishing in the EEZs of these island nations and on the high seas itself. During the course of this operation, "Preble" encountered multiple vessels conducting fishing operations in EEZ. All the data was reported to USCG District 14 for evaluation and follow-on action via the embarked Coast Guard liaison team. Also, "Preble"s embarked detachment of Sikorsky SH-60 Seahawk helicopters from squadron HSL-43 was used to conduct routine aerial patrols, enabling the surveillance team to search multiple areas of interest.
