Historical Case Study Analysis: World War II Southwest Pacific Area Theater of Operations Ports of Debarkation

Conventional Army forces have long been absent from the land areas of the southwestern Pacific. This study would help twenty-first-century transportation planners understand the historical uses of key ports and terminals used by US forces during the last major land operation in this part of the world. It should focus on how access and basing rights developed from the late nineteenth century to the World War II period to inform planners of the geopolitical history of the region.

• Baptiste, LCDR Ryan P., "Sustaining the Fight: Innovations to Enhance Naval Logistics in INDOPACOM's Contested Environment," AFGC thesis, 2025.
  • Answers the query by framing the "logistical revolution" of the WWII Pacific Theater as a foundational case study for overcoming a lack of established ports and terminals. The research highlights that because traditional, fixed bases were often unavailable or highly contested, the U.S. Navy developed mobile logistics groups—including fleet oilers, tenders, and floating drydocks—to sustain maritime operations. By detailing how underway replenishment allowed U.S. forces to operate far from fixed ports and leapfrog Japanese strongholds, this paper informs twenty-first-century planners on how historical forces successfully projected power and sustained operations across the vast distances of the Pacific without relying solely on terrestrial infrastructure.

  • Bostic argues that appreciating the current US posture requires analyzing how the historical footprint was formed, offering lessons on how to establish new operating locations while avoiding past errors. This historical perspective helps explain how diverse cultures, immense distances, and interconnected sea lanes have shaped access and cooperative security locations over time.
• Croft, CDR Michael E., "Navy Expeditionary Cargo Handling: Manpower Challenges," AFGC thesis, 2020.
  • While primarily focused on modern Navy expeditionary cargo handling, this paper addresses the query by connecting modern logistical frameworks to the history of World War II Pacific operations. Croft relies on historical analyses of amphibious operations and the critical role of military logistics during the Pacific War to contextualize how forces manage expeditionary cargo. By highlighting the historical necessity of expeditionary logistics, this paper provides a bridge between the massive supply chains of WWII Pacific campaigns and the requirements for operating ports and terminals in contested maritime environments.
• Endicott, Maj. Kenneth M. Endicott, "USMC Force Design 2030 in Historical Context," AFGC thesis, 2023.
  • Answers the query by providing case studies on historical military preparations for Pacific operations, specifically examining the creation of the "Advanced Base Force" and the evolution of amphibious assault concepts prior to World War II. The paper references early 20th-century efforts—such as the formation of the Advance Base Force in 1913-1914—to establish expeditionary footholds from the sea. By reviewing how the US military historically designed its forces to secure basing and project power in the Pacific, this research gives planners insight into the historical doctrine and organizational shifts that enabled World War II land and maritime operations.
• Georgulis, Lt. Col. Grant M., "Victory through Air and Sea Power: A 21st Century Primer," SAASS thesis, 2021.
  • Addresses the prompt by examining the development of US basing rights in the Pacific from the late nineteenth century through World War II to demonstrate how strategic expeditionary points arbitrate control. The paper traces the geopolitical history of the region by highlighting the 1898 annexation of Hawaii and the 1900 acquisition of the Philippines, which spurred the creation of War Plan Orange to prepare for a potential conflict with Japan. By detailing how the US Navy systematically acquired islands during the World War II Pacific campaign to serve as deep harbors for fleet sustainment and critical supply line nodes, Georgulis provides twenty-first-century planners with a historical model of how establishing forward operating bases and securing maritime lines of communication are essential for projecting power across vast distances.
• Gulick, Branden W., "To the Ends of the Earth and Beyond: A Strategic Analysis of the Sustainability of the Unified Command Plan," SAASS thesis, 2023.
  • Addresses the prompt by exploring the strategic and logistical foundations of the WWII Pacific campaign, specifically the island-hopping strategy and the development of War Plan Orange. The author explains how half a century of war planning culminated in the realization that the U.S. needed to dominate sea lanes and rely on islands like the Philippines and Guam as vital forward projections for air and seapower. By analyzing the massive costs associated with moving across the Pacific, the paper provides planners with an understanding of the "genesis of American interest in the first island chain" and how historical basing requirements were driven by the need to secure critical resources and prevent strategic surprise.
• Langan, Lt. Col. Dan, "CAF Flightline Maintenance Should Reorganize to Align with AFFORGEN," AF Fellows (Argonne National Lab), 2024.
  • Addresses the historical use of Pacific bases by reflecting on the extreme logistical difficulties U.S. forces faced during campaigns in the Southwest Pacific, such as Guadalcanal. The author notes that during WWII, U.S. forces fought to secure and hold airfields throughout the first and second island chains while under constant enemy attack, forcing them to overcome contested logistics along multiple legs of the supply chain. This study aids modern transportation planners by demonstrating that the historical use of these regional hubs required a unified command structure capable of marshaling all available manpower and resources to survive the chaotic and contested environment of a forward-deployed Pacific airfield.
• MacDonald, Maj. Andrew, "Off-Ramps in the Pacific: National Character and the Mismanagement of the Great Power Competition," SAASS thesis, 2021.
  • Addresses the prompt's focus on the geopolitical history of the region by tracing the strategic relationship between the United States and Japan from the nineteenth century through 1941. To inform planners about the environment preceding the last major land operations in the Southwest Pacific, the study explores how the two nations developed inherently tense, escalatory approaches to the international order as they expanded their influence across a shared Pacific frontier. By analyzing historical concepts like Manifest Destiny and the competition for regional hegemony, MacDonald provides deep contextual background on the strategic tensions and national characteristics that ultimately shaped US access disputes and the onset of the World War II Pacific theater
• McKittrick, LTC J. Kevin, "A Long and Costly Fight: How Historical Insight from Operation Causeway Can Still Deter Aggression Today," AWC SSP, 2024.
  • Contributes to the topic by examining the logistical constraints of a specific, major WWII Pacific theater operation: the planned 1944 amphibious invasion of Formosa (Taiwan). The paper details how senior military leaders debated the use of Formosa as a major operational base and terminal, ultimately concluding that a lack of resources and severe logistical constraints would make securing the island too long and costly of a fight. This historical analysis of the Joint Planning Staff's decision-making process helps modern planners understand the immense supply chain vulnerabilities and resource requirements that dictated the use—or bypassing—of major land areas and ports in the region during WWII.
• Melendez, LCDR Michael A., "Enemy on Island, Situation in Doubt: Climate Change's Implications to Wake Island's Strategic Importance," AFGC thesis, 2022.
  • Answers the prompt by tracing the geopolitical history and strategic importance of Pacific island bases from the late nineteenth century to the World War II era. The paper explains that the transition from the age of sail to coal-powered ships during the industrial revolution necessitated the establishment of a global network of coal refueling ports. Melendez links this early requirement for maritime access to the height of the World War II era, specifically noting how General Douglas MacArthur’s "Island Hopping" campaign relied on capturing entrenched island fortresses to serve as operational footholds. By focusing on Wake Island's historical past, the author helps modern transportation planners understand how these small but critical land masses evolved into indispensable logistical nodes for US power projection in the Indo-Pacific.
• Skilling, Maj. Ryan, "Semper Fi to Semper Supra: Lessons for the USSF on Organizational Efficiency and Effectiveness from 246 Years of United States Marine Corps History," SAASS thesis, 2022.
  • Contributes to the historical geopolitical context by analyzing the strategic shifts in the Pacific following World War I and the rise of Japan. Skilling details how the United States, fearing a threat to its Pacific interests, began focusing its operational planning on the ability to seize enemy bases via amphibious assault. This paper helps explain the strategic drivers that forced the US to rethink its Pacific basing and access rights in the early 20th century, culminating in the major operational concepts utilized during the Pacific campaigns of World War II.
• Spinella, Thomas W., "A Tale of Two Airbases: A Comparative Analysis of US Government Airbase divestment and Retainment Decisions," SAASS thesis, 2025.
  • Answers the query by providing a detailed geopolitical history of U.S. basing rights in the Pacific, tracing their development from the late nineteenth century through World War II. The paper highlights that the U.S. acquisition of the Philippines following the 1898 Spanish-American War marked its transition to an imperial power, aligning with Alfred Thayer Mahan’s naval theories that advocated for strategically located bases to project American power. By detailing how early military planners envisioned the Philippines as a “Great Western Base” to counter Japanese expansion and protect economic interests, this study offers transportation planners crucial historical context regarding how the U.S. initially secured and utilized access and basing rights in the region.
• Walsh, Lt. Col. Sean, "Enhancing Fuel Support to Expeditionary Advanced Base Operations through Autonomous Unmanned Technologies," AWC SSP, 2020.
  • Explores the development of Pacific basing and access during the interwar period and World War II, specifically focusing on the Marine Corps' strategy to seize advanced naval bases. Walsh highlights how planners developed Operations Plan 712 for Advanced Based Operations in Micronesia to counter Japan's fortified island chains and anti-access strategies. By detailing the historical necessity of capturing and sustaining expeditionary bases in the Pacific Campaign, this paper offers transportation planners valuable context regarding the logistical challenges of establishing footholds in contested Pacific environments.
