Blocking Foreign Cellular Modules in Defense Systems Act of 2026

Current understanding

A House bill introduced in the 119th Congress would restrict or ban the use of foreign-made cellular modules in U.S. defense systems, extending the pattern of component-specific adversary-nation sourcing prohibitions in DoD acquisition. Status: introduced and referred to committee, with no enacted effect. Practical and fiscal implications depend on scope (which modules, which ‘foreign’ sources, transition timelines) and are not yet detailed.
