The warning is credible as a supply-chain and readiness risk, but it does not mean the Pentagon has published a single inventory count showing that the military is running out of chips. The strongest public evidence points to heavy overseas concentration in semiconductor production, limited visibility into where chips embedded in military systems are made, and insufficient secure capacity for some advanced and specialized needs.
What “dangerously low” means—and what it does not
“Dangerously low” is an expert warning about the resilience of the supply chain, not a formal Department of Defense (DOD) threshold or a published measure of the military’s total chip inventory. Public evidence does not establish one comprehensive number for how many chips the U.S. military has in stock, or how long its supplies would last in a conflict.
The concern is about whether the United States can reliably obtain, verify, and scale production of the microelectronics used in defense systems—especially if overseas production or transport is disrupted, demand surges, or a specialized part is no longer made commercially.
How much semiconductor production is overseas?
DOD officials told the U.S. Government Accountability Office (GAO) that an estimated 88% of microelectronics production and 98% of assembly, packaging, and testing take place overseas, primarily in Taiwan, South Korea, and China. GAO reported these estimates in 2025 in report GAO-25-107283. They describe the production landscape, not the share of every chip in every military system that comes from a particular country.

The distinction between making a chip and completing it matters. A chip can be designed in one place, fabricated on a wafer in another, then assembled, packaged, and tested elsewhere. Those later steps are essential to delivering a usable component, so overseas concentration in them creates exposure even when wafer fabrication is domestic.
Former House Permanent Select Committee on Intelligence chairman Mike Rogers told EE Times that the United States has “some unique capability” to produce high-end chips, but not at the volume needed. He added that the country supplements domestic production with purchases around the world, including China, and said, “We should never have put ourselves in that position. We’re going to have to unwind it.”
What the procurement figures show
GAO reported that DOD procured $1.3 billion of electronic microcircuits in fiscal years 2020 through 2024. More than $400 million of one type came from DOD-accredited trusted suppliers using commercial domestic foundry processes. These figures show that trusted domestic sourcing is already part of procurement; they do not represent the total value of military semiconductor use or prove that all defense needs can be met by those suppliers.
DOD depends on a global network of more than 200,000 suppliers, according to GAO’s 2025 report. The scale of that network makes it difficult to track every component beyond a direct contractor, particularly when chips are embedded in commercial equipment or pass through multiple lower-tier suppliers.
Why military chips are not interchangeable with consumer chips
Defense demand often differs from the commercial market in volume, lifetime, and performance requirements. A military program may need a relatively small number of a specialized part over many years, while commercial fabs are optimized for high-volume products and faster technology cycles. If a commercial supplier stops making a compatible chip, maintaining a defense-unique or legacy part may require dedicated capacity or a redesign and requalification of the system.
The challenge is not limited to the latest processor. DOD’s concerns span chip design, wafer fabrication, assembly, packaging, and testing. Military applications can also require specialized components, including radiation-hardened, radio-frequency, and electro-optical chips. The Congressional Research Service describes these issues as part of the broader defense microelectronics supply chain.

Advanced computing presents a separate capacity problem. EE Times reported expert testimony that small U.S. foundries can support older 90-nanometer and 130-nanometer work but cannot satisfy every advanced-chip need. The article quoted the assessment, “No trusted fab does 5-nm compute.” That statement concerns trusted domestic capacity for a particular leading-edge class of compute; it does not mean that all military systems require 5-nanometer chips.
Where the supply-chain risk is most acute
| Supply-chain area | What the evidence says | Why it matters |
|---|---|---|
| Advanced compute | Experts cited by EE Times said secure U.S. capacity is not sufficient for all advanced-chip needs, including 5-nanometer compute. | Some high-performance applications may depend on capacity that is not available from a trusted domestic source at the required scale. |
| Legacy and specialized parts | DOD needs low-volume, long-lived parts as well as specialized chips; small U.S. foundries can support some older 90-nanometer and 130-nanometer work, according to expert testimony reported by EE Times. | Commercial production may not continue at the volume or for the duration defense programs require. |
| Assembly, packaging, and testing | DOD officials estimated that 98% of these activities occur overseas, primarily in Taiwan, South Korea, and China; GAO reported the estimate in 2025. | Domestic wafer fabrication alone would not remove exposure if later production steps remain concentrated abroad. |
| Lower-tier sourcing visibility | GAO found that DOD cannot identify where all microelectronics in procured goods are manufactured. | Decision-makers may not know the origin of components embedded in products bought through contractors and sub-tier suppliers. |
TechInsights analyst Dan Hutcheson told EE Times that U.S. smart-munitions stockpiles had become “seriously depleted” and that they mostly rely on “More-than-Moore” solutions. This is a specific expert statement about smart-munitions inventories and the types of technologies they use, not evidence of a measured depletion level across all military chips or weapons.
Why procurement records do not settle the origin question
GAO found an apparent contradiction: federal procurement records showed the United States as the place of manufacture and country of origin for nearly 100% of reported electronic-microcircuit obligations, yet DOD officials remained concerned that commercial microelectronics embedded in DOD goods originate outside the United States.

The records do not provide a complete map of lower-tier suppliers and component origins. A recorded country for a procurement obligation is not necessarily a trace of every chip inside the delivered product. The gap matters because DOD cannot fully assess exposure to overseas production if it cannot see the parts flowing through the entire supply chain.
Visibility tools are being developed across the department, including SCREEn, DIBMAP, Navy supply-chain illumination efforts, and Air Force FirstLook. GAO found these efforts generally early, fragmented, and incomplete, with DOD not having fully identified the resources, priorities, and timelines needed to integrate them. A 2024 Air Force assessment found commercial supply-chain tools only 60% to 70% accurate, as reported by GAO in 2025—an illustration of how difficult it is to turn supplier data into a dependable picture.

DOD uses accredited trusted suppliers and trusted-foundry or trusted-supplier standards intended to reduce risks across design, fabrication, packaging, testing, and distribution. The Congressional Research Service also describes MINSEC, an effort to preserve secure state-of-the-art capability alongside specialized military niches such as radiation-hardened, RF, and electro-optical chips.

A secure fab does not by itself solve a shortage of packaging capacity; domestic capacity does not guarantee visibility into every embedded commercial component; and a leading-edge facility does not automatically make long-lived legacy parts. A more resilient approach therefore has to match the remedy to the chip and the production step at risk.
- Expand domestic and allied capacity: More secure sources can reduce reliance on concentrated overseas production, but capacity must cover the processes DOD actually needs, not just wafer fabrication.
- Preserve specialized and legacy production: Low-volume defense demand may require support for parts that commercial producers would otherwise discontinue.
- Improve supply-chain monitoring: Better lower-tier and country-of-origin data can help DOD identify dependencies before a disruption.
- Develop the workforce and coordinate policy: In a 2022 GAO study, all 17 experts interviewed agreed workforce development needed action. They also said no single policy intervention would solve semiconductor supply-chain risk.
These are complementary measures, not substitutes. The relevant comparison is whether a source is trusted, whether it can supply advanced or specialized parts, which production stages it covers, and whether it can serve defense demand that may be small and sustained rather than large and short-lived.
What this means for military readiness
Chip supply is a readiness issue because microelectronics support weapons, communications, sensors, and other defense systems, while delays or a loss of a specialized component can complicate procurement and sustainment. The documented risks are overseas production concentration, incomplete origin tracing, limited secure capacity in some areas, and concerns about smart-munitions inventories. They justify concern about resilience and surge capability, but they do not establish that the entire military is out of chips.
The most accurate reading of the warning is therefore specific: the United States has trusted capabilities and is pursuing ways to secure supply, yet DOD remains exposed to global concentration and cannot fully see the origins of all microelectronics in its systems. Whether a particular program faces an immediate shortage depends on the parts it uses and the suppliers behind them; the available public evidence does not provide a single military-wide stockpile figure.
