Contested Logistics in the Pacific Theater Lacks Protected Resupply Routes

A conflict in the Western Pacific — most plausibly a Taiwan contingency — would require the United States to sustain forces across 5,000+ miles of ocean within range of China's anti-access/area-denial (A2/AD) capabilities. China's DF-26 intermediate-range ballistic missiles can strike Guam. Its DF-21D anti-ship ballistic missiles threaten surface vessels across the first island chain. Its submarine fleet, air-launched cruise missiles, and cyber capabilities can target logistics nodes from ports to airfields. The United States has not fought a war where its logistics lines were seriously contested since World War II, and the current force is not structured for it. This matters because every bullet, missile, meal, and gallon of fuel consumed in a Pacific fight must cross an ocean that an adversary can attack. Unlike European scenarios where NATO has land-based supply lines and multiple ports, the Pacific theater offers no such luxury. Forces on Guam, Okinawa, the Philippines, and at sea depend entirely on air and sea lines of communication that pass through contested space. If China can interdict even a fraction of resupply shipments, U.S. forces run out of munitions and fuel within days to weeks. Wargames conducted by RAND, CSIS, and the Pentagon consistently show that logistics, not combat power, is the binding constraint in a Taiwan scenario. The consequences are stark. Without reliable resupply, forward-deployed forces become a wasting asset. Aircraft without missiles and fuel are targets, not weapons. Ships without munitions must withdraw. The entire concept of sustained operations in the Western Pacific depends on solving the contested logistics problem, and the U.S. military has not yet demonstrated a credible solution at scale. Distributed operations concepts like Agile Combat Employment and Expeditionary Advanced Base Operations are promising but remain largely experimental. This problem persists because U.S. logistics planning since 1991 has assumed uncontested rear areas and secure supply lines. The wars in Iraq and Afghanistan involved long supply lines vulnerable to IEDs and ambushes, but the ports, airfields, and sea lanes connecting the U.S. homeland to theater were never at risk. An entire generation of logisticians was trained in an environment where the supply chain started at a secure port and ended at a forward operating base, with the only threats in between being small arms and improvised explosives. The mental model and institutional muscle memory are wrong for great power competition. Structurally, the U.S. military's logistics enterprise is centralized and hub-dependent. Major logistics hubs like Guam, Kadena Air Base, and Yokosuka Naval Base are known, fixed targets that China has been planning to strike for decades. Dispersing logistics across many small, austere locations is doctrinally appealing but operationally difficult — it requires different equipment, different training, different command relationships, and different contracts with host nations. The transformation required is not incremental; it is a fundamental redesign of how the joint force sustains itself in combat.
