Pentagon ordered to audit and remove Chinese wireless chips from defense systems

What it does

This bill requires the Department of Defense to audit all military systems and infrastructure within 180 days to identify cellular modules (wireless connectivity components) made by Chinese entities or other foreign suppliers deemed a security risk, then report back to Congress within one year on what was found and how the Pentagon plans to remove or isolate those components. The bill benefits U.S. national security by forcing visibility into supply-chain vulnerabilities in defense systems; it costs the Pentagon time and money to conduct the audit and replace risky hardware.

Why we flagged it

The bill's core mechanism is a mandatory audit and mitigation program targeting foreign-supplied cellular modules in defense systems. It is a security-focused inventory and remediation mandate, not a procurement reform, not a deregulation, and not a carve-out—it is straightforward national-security housekeeping.

What the text implies

• The audit may reveal the scale of Chinese-supplied components already embedded in U.S. defense infrastructure, potentially exposing a larger vulnerability than currently public.
• Mitigation timelines (up to 6 years of reporting) mean some risky modules may remain in place for years while replacement is planned, creating a window of continued exposure.
• The bill defines 'covered cellular module' broadly to include any module from entities 'determined by the Secretary of Defense to present an unacceptable supply-chain risk,' giving DoD discretion to expand the scope beyond China-linked suppliers.
• Contractors operating defense systems may face significant costs and operational disruption during rip-and-replace cycles, which could be passed to the Pentagon or delayed if contractors lobby for exemptions.
• The unclassified reporting requirement may limit what Congress learns about specific vulnerabilities or the full scope of foreign penetration, even as it improves transparency relative to no reporting.

Who it affects

The bill strengthens national security by forcing the Pentagon to identify and mitigate foreign-supplied wireless components in defense infrastructure, reducing the risk of espionage or sabotage through compromised hardware. Citizens benefit from a more transparent, accountable process: Congress receives unclassified reports on what was found and how the Pentagon is fixing it, and the Comptroller General independently verifies implementation. The cost is borne by the defense budget (audit and re

Who stands to gain

• U.S. defense contractors (replacement hardware suppliers)
• Cybersecurity and network segmentation vendors
• Defense system integrators and retrofit service providers
