HONOLULU – The crew of USCGC Harriet Lane (WMEC 903) returned to Honolulu Saturday following an 81-day patrol in support of Coast Guard Oceania District’s Operation Blue Pacific.
The Harriet Lane crew departed Joint Base Pearl Harbor-Hickam in September to conduct joint operations and territorial integrity missions across Oceania. Patrolling more than 16,000 nautical miles throughout Oceania to include the Republic of the Marshall Islands, Papua New Guinea, Vanuatu, Tonga, and American Samoa, the cutter’s crew worked alongside interagency and Pacific Island partners to deter transnational criminal organization activities, facilitate the flow of commerce, and protect critical ocean resources.
“This patrol was a resounding success for the crew of Harriet Lane and reinforced the Coast Guard’s commitment as a trusted partner across Oceania,” said Cmdr. Justin Matejka, commanding officer, Harriet Lane. “It was a pleasure to partner with the many professional officers from multiple Pacific Island Countries to combat illegal, unreported, and unregulated fishing and transnational criminal organization activity. I am proud of the crew’s incredible commitment to operational success and look forward to being a part of Harriet Lane’s growing impact across the region.”
The Harriet Lane crew exercised partnerships with the Marshall Islands, Papua New Guinea, Vanuatu, and Tonga through bilateral maritime law enforcement agreements, professional exchanges, and domestic federal maritime law enforcement operations. In total, the Harriet Lane crew and Pacific Island enforcement officers conducted 31 boardings of fishing vessels, resulting in 20 potential violations.
The crew conducted 15 additional high seas boarding and inspections on commercial fishing vessels, resulting in 2 potential violations of conservation and management measures under the Western and Central Fisheries Commission.
Enhancing diplomatic relationships within the Pacific Quadrilateral Defence Coordinating Group, the Harriet Lane crew also integrated Royal New Zealand Navy sea riders for a portion of the patrol.
Harriet Lane’s visit to Tonga included strategic discussions with Defense and Foreign Minister, Crown Prince Tupouto’a ‘Ulukalala, focusing on enhancing bilateral cooperation to address maritime security threats and counter illegal, unreported, and unregulated fishing activity in the region.
Commissioned in 1984, Harriet Lane is a 270-foot medium endurance cutter homeported in Honolulu to support Coast Guard missions in the Pacific region. The service’s medium endurance cutter fleet supports a variety of Coast Guard missions including search and rescue, law enforcement, maritime defense, and protection of the marine environment.

The Coast Guard currently has 22 medium endurance cutters. Only three are in the Pacific Area, one in Alaska, one on the West coast, and one in Hawaii despite the fact 85% of the US EEZ is in the Pacific Area.
If we add in the NSCs, the Coast Guard has 32 large patrol cutters and only nine of them are in Pacific Area.
