Central Pacific Area (CPAC) The Central Pacific Area (CPAC) is an operational designation used in strategic planning and coordination for maritime, air, and joint activities across the central Pacific Ocean region. It provides a geographic construct for coordinating forces, assets, and logistics among allied and partner commands, linking strategic hubs such as Pearl Harbor, Guam, and Kwajalein to operations involving long-range strike, surveillance, and sea control. CPAC intersects with theaters, commands, and multinational arrangements that include Pacific Rim capitals, regional bases, and treaty organizations.
CPAC functions as a coordination and operational planning zone that aligns with assets from United States Indo-Pacific Command, United States Pacific Fleet, United States Air Force Pacific Air Forces, United States Marine Corps Forces Pacific, and partner forces from Japan Self-Defense Forces, Australian Defence Force, Republic of Korea Armed Forces, and Philippine Armed Forces. It serves as a nexus between strategic nodes like Pearl Harbor Naval Base, Andersen Air Force Base, Guam, Kwajalein Atoll, Wake Island, and logistical hubs such as Diego Garcia and Hickam Field. CPAC is referenced in contingency plans involving the United Nations Command, North Atlantic Treaty Organization liaison efforts, and trilateral frameworks such as the Quadrilateral Security Dialogue and AUKUS-related cooperation. Command relationships often intersect with established agreements such as the US-Japan Security Treaty, the US-Philippines Visiting Forces Agreement, and arrangements tied to the Compact of Free Association.
Geographically, CPAC spans oceanic areas including parts of the Central Pacific Basin, the Line Islands, the Marshall Islands, the Caroline Islands, and maritime approaches to the Hawaiian Islands. Its boundaries are defined relative to strategic waypoints used by Seventh Fleet transit routes, Task Force 72 areas, and surveillance corridors linking Midway Atoll with Wake Island and the broader Micronesia region. CPAC’s maritime jurisdictional considerations interact with Exclusive Economic Zones of states such as Kiribati, Federated States of Micronesia, Marshall Islands (nation), Nauru, and Samoa while overlapping navigational lanes used by vessels from China National Offshore Oil Corporation-affiliated fleets, Mitsui O.S.K. Lines, and multinational merchant convoys.
CPAC’s responsibilities include maritime domain awareness tasks executed by platforms from National Reconnaissance Office-assisted satellites, Naval Oceanographic Office research, long-range patrols by Boeing P-8 Poseidon squadrons, and signals collection by assets linked to National Security Agency partnerships. It supports logistics throughput for expeditionary forces using Military Sealift Command vessels, prepositioned stocks such as those at Naval Magazine Guam, and airlift operations by Air Mobility Command and Civil Reserve Air Fleet components. Crisis response coordination involves entities such as United States Agency for International Development disaster teams, Red Cross contingencies, and civil-military cooperation with organizations like Pacific Islands Forum and Secretariat of the Pacific Community.
CPAC is not a single standing command but a planning construct that binds elements of United States Strategic Command tasking, United States Northern Command liaison elements, and theater force providers including the III MEF and transient units from Carrier Strike Group One and Carrier Air Wing Two. Staff functions draw personnel with expertise from the Defense Intelligence Agency, Joint Chiefs of Staff planning directorates, and affiliated national attachés from Ministry of Foreign Affairs (Japan), Department of Defence (Australia), and Ministry of National Defense (Republic of Korea). Logistics coordination uses nodes such as Andersen Logistics Complex, Naval Supply Systems Command, and civil port authorities like Port of Honolulu.
CPAC evolved from mid-20th century theater delineations established during campaigns involving United States Pacific Fleet (World War II), South Pacific Area (World War II), and operations tied to the Battle of Midway and Guadalcanal Campaign. Cold War developments incorporated assets from Strategic Air Command forward basing, signals links to ECHELON-related networks, and coordination with ANZUS partners. Post-Cold War restructuring saw CPAC concepts absorb lessons from operations such as Operation Desert Storm logistics, humanitarian missions exemplified by Operation Tomodachi, and disaster relief after Typhoon Haiyan. Recent doctrinal shifts reference scenarios involving Freedom of Navigation Operations and multinational exercises led by United States Indo-Pacific Command.
CPAC hosts recurring multinational exercises and operations including elements of Rim of the Pacific Exercise, Malabar (naval exercise), Talisman Sabre, Balikatan, Cobra Gold, and Keen Sword where naval, air, and amphibious forces rehearse sea control, strike, and civil assistance. Training events involve units such as Marines from 3rd Marine Expeditionary Force, P-8 squadrons from VP-5, and carrier assets like USS Ronald Reagan (CVN-76), USS Nimitz (CVN-68), and USS Carl Vinson (CVN-70). Exercises incorporate unmanned systems from manufacturers like General Atomics and Boeing and integrate command-and-control systems such as Aegis Combat System and Link 16 networks. Law enforcement and counter-narcotics operations coordinate with agencies including United States Coast Guard and regional police forces.
CPAC’s effectiveness depends on diplomatic and defense ties with nations and organizations including Japan, Australia, South Korea, Philippines, New Zealand, France (French Polynesia), and Pacific island states associated through the Pacific Islands Forum and the Compact of Free Association. Partnerships involve interoperability standards from North Atlantic Treaty Organization-derived protocols, bilateral agreements like the US-Japan Status of Forces Agreement, and trilateral initiatives exemplified by Japan-Australia-United States consultations. Civilian agencies such as United States Agency for International Development and international bodies like the International Federation of Red Cross and Red Crescent Societies participate in planning for humanitarian assistance across the CPAC area.
