Blocking Foreign Cellular Modules in Defense Systems Act of 2026
Key claim: A House bill would restrict or ban foreign-made cellular modules from being used in U.S. defense systems.
Abstract
(HR10861 · 119th Congress) Latest action (2026-10-22): Referred to the House Committee on Armed Services.
Why this matters
Cellular modules are ubiquitous in modern defense platforms (sensors, logistics tracking, communications, UAS) and have been a recurring vector for supply-chain and signals-intelligence concerns involving PRC-based vendors. The bill would extend the component-specific prohibition model already applied to printed circuit boards and certain batteries, tightening DoD’s foreign-adversary exposure in connected hardware. As an introduced House measure with only committee referral, it has no operational effect yet, but it signals continued congressional appetite for narrow, SKU-level supply-chain bans in defense procurement.
