The Army Contracting Command - Redstone is issuing a Request for Information (RFI) regarding a pending modification to an existing sole-source contract for the Gateway Mission Router (GMR), which provides secure wireless data for soldier situational awareness and command and control. The modification would add a fifth ordering period, a new hardware variant, and increase the contract ceiling due to higher-than-anticipated demand. The contract is managed at Fort Belvoir, VA, and the GMR integrates with tactical datalinks for air and ground vehicles. Responses to this RFI must be submitted by 29 May 2026 to inform a sole source determination. No budget amounts are specified in the description.
