Gateway Mission Router is documented as a communications and command-and-control integration system, not a standalone weapon. Public V2X and government sources support its air-to-ground connectivity role, open-standard interfaces, platform independence, Army Air Warrior hardware context, and CJADC2 relevance; they do not publish a complete hardware datasheet or fielded inventory.
Air Warrior hardwarePublic contract records describe Gateway Mission Router hardware and GMR variants in support of U.S. Army Air Warrior requirements.
Gateway functionV2X says GMR routes datalinks and platform capabilities so situational-awareness and command-and-control information can be merged across formats.
Sourcing limitAvailable public sources identify role, program context, and contract values, but not complete radio interfaces, encryption implementation, dimensions, power draw, or delivered quantities.
