When Adm. Samuel Paparo, the four-star commander responsible for deterring China across the Pacific, told the Associated Press that U.S. arms shipments to Ukraine and Israel were “eating into” the weapons his forces would need in a crisis, he was not speaking in hypotheticals. He was describing a trade-off the Pentagon has been making for years and is now struggling to reverse.
As of spring 2026, the United States faces a widening gap between the munitions it considers essential for a conflict in the Western Pacific and the stockpiles it actually holds. Anti-ship missiles, long-range strike weapons, and air defense interceptors have flowed to partners fighting active wars in Europe and the Middle East. Replacing them has proven far slower than spending them. The result, according to congressional testimony, Pentagon budget documents, and public statements from senior commanders, is a readiness shortfall in the theater the Defense Department has designated its top priority.
Years of drawdowns, slow recovery
The scale of the problem has been building since at least 2022, when the United States began large-scale arms transfers to Ukraine following Russia’s full-scale invasion. Subsequent support packages to Israel compounded the pressure. The weapons most affected overlap significantly with those Pentagon war planners have earmarked for a Taiwan contingency or a confrontation in the South China Sea: precision-guided munitions, surface-to-air interceptors, and anti-ship cruise missiles.
During a Senate Armed Services Committee hearing held during the 118th Congress (2023-2024) on the fiscal year 2024 defense authorization request, lawmakers and Defense Department officials treated munitions procurement as a readiness bottleneck. Witnesses described a situation in which the military had enough personnel and platforms but not enough weapons to load onto them at the pace a major war would demand. The hearing record, designated S.Hrg. 118-625, captured bipartisan alarm about the mismatch between inventory levels and operational requirements. That alarm has not subsided; as of April 2026, the shortfalls identified in that testimony remain a central reference point in ongoing defense debates.
That alarm translated into contracting changes. A Congressional Research Service report on the FY2024 munitions request (R47582) documented the Pentagon’s shift toward multiyear procurement and large-lot contracts for precision-guided weapons, noting that these tools were adopted specifically because standard annual procurement had failed to keep pace with demand. These are not routine purchasing tools. They exist to signal long-term commitment to manufacturers, encouraging them to invest in new production lines, hire specialized workers, and secure long-lead components like rocket motors and seekers that can take 18 to 24 months to deliver.
A separate CRS analysis of FY2026 munitions funding (R48860) consolidated missile and munitions accounts into a single comparison of what the Pentagon requested and what Congress authorized. The gaps in that crosswalk reveal where lawmakers and defense officials disagree on priorities. In several cases, Congress added funding for specific missile programs it viewed as critical to Pacific deterrence while trimming others, effectively overriding the Pentagon’s own sequencing.
The Pacific commander’s warning
Paparo’s public comments carried unusual weight because of who he is and what he commands. As head of U.S. Indo-Pacific Command, he oversees roughly 380,000 military personnel and is the officer who would direct American forces in a fight over Taiwan or freedom of navigation in contested waters. When he told reporters that concurrent aid missions were degrading his readiness, he was placing a combatant commander’s credibility behind a claim that had previously circulated mostly in budget documents and think-tank reports.
The Pentagon’s own actions reinforced his words. In early 2025, defense officials paused certain arms shipments to Ukraine as part of a global review of munitions allocation, specifically citing pressure on high-demand air defense interceptors. That review covered worldwide stockpile distribution, not just a single theater, and its existence confirmed that depletion had moved from a planning concern to an operational constraint shaping real-time decisions about which allies receive weapons and when.
The pause also highlighted an uncomfortable reality: the United States was, in effect, choosing between supporting partners under fire today and preserving the arsenal it might need for a larger war tomorrow. That is not a theoretical dilemma. It is a resource allocation problem with concrete consequences for deterrence.
What the public record does not show
For all the official concern, several critical details remain classified or simply unavailable. No public source provides exact current inventory levels for weapons like the Long Range Anti-Ship Missile (LRASM), the Joint Air-to-Surface Standoff Missile (JASSM), or the Standard Missile-6 (SM-6) interceptor. Without those numbers, it is impossible to calculate how many days or weeks of high-intensity combat the existing stockpile could sustain.
Production rates are similarly opaque. CRS reports document how much money Congress appropriated, but appropriations are not the same as delivered rounds. Factory capacity, not funding alone, often determines how quickly stocks recover. Bottlenecks in specialized components, testing infrastructure, and a shrinking pool of skilled defense manufacturing workers can slow output even when budgets rise sharply.
The direct link between specific aid packages and specific Indo-Pacific shortfalls also lacks granular public documentation. Paparo’s comments establish that simultaneous commitments are straining reserves, but no unclassified Defense Department statement quantifies how many interceptors or anti-ship weapons were drawn from Pacific-oriented stocks versus other regional allocations or war reserve categories. The Pentagon’s global review may eventually produce that accounting, but its detailed findings have not been released.
The other side of the equation
Any assessment of U.S. readiness in the Pacific is incomplete without considering what China has been doing on its side of the ledger. The People’s Liberation Army has spent the past decade expanding its own missile arsenal at a pace that dwarfs American production. China’s shipbuilding output now exceeds that of the United States by a wide margin, and its stockpiles of anti-ship ballistic missiles, cruise missiles, and advanced air defense systems have grown steadily.
That buildup is the backdrop against which American depletion matters most. A munitions gap is not just about absolute numbers; it is about the ratio between what the U.S. can bring to a fight and what an adversary can throw at it. If American stocks shrink while Chinese inventories grow, the deterrent effect of forward-deployed U.S. forces erodes even if those forces remain technologically superior on a per-unit basis.
Allied contributions offer a partial counterweight. Japan has invested heavily in its own standoff missile capabilities and is co-producing variants of the SM-3 interceptor. Australia’s Guided Weapons and Explosive Ordnance enterprise, a centerpiece of the AUKUS partnership, aims to build sovereign manufacturing capacity for precision munitions. But those programs are still ramping up, and none is yet producing at a scale that would offset the drawdowns from U.S. stockpiles.
Where the risk sits in spring 2026
The strongest evidence in this story comes from primary government sources: sworn congressional testimony, nonpartisan CRS budget analyses, and on-the-record statements from the combatant commander responsible for the Pacific. Together, they establish an institutional consensus that munitions procurement has not kept pace with demand, that special contracting tools have been deployed to close the gap, and that the gap remains significant enough to influence real policy decisions about arms transfers.
What the evidence does not support is a precise timeline for when depletion could reach a critical threshold or a specific scenario in which the United States would be unable to respond to Chinese military action. Those judgments require classified data on inventory levels, production output, and war-planning assumptions that remain outside public view.
The most honest reading of the available information is this: U.S. munitions inventories are under documented strain from simultaneous commitments in Europe, the Middle East, and the Indo-Pacific. Policymakers are working to rebuild capacity through expanded contracts and allied partnerships, but production timelines measured in years are colliding with a strategic environment that could shift in months. The margin for error in the Western Pacific is thinner than senior commanders want it to be, and until factory floors catch up with geopolitical demand, that margin will remain a source of genuine concern.
