The Department of Defense, through the Army Contracting Command – Aberdeen Proving Ground, is announcing an Advance Notice for the Soldier Borne Mission Command (SBMC) Other Transaction (OT) Opportunity aimed at developing a fused digital awareness system for dismounted operations. This initiative seeks to create a rapid prototyping project that integrates emerging modular sensor technologies while ensuring compatibility with the existing Android Tactical Assault Kit (ATAK) architecture. The Government plans to award one or more OT agreements to prime contractors capable of delivering comprehensive solutions, with prototypes expected within seven months of award. Interested vendors must have a current Facility Clearance or a Military Critical Technology Data Agreement to access the draft Statement of Work and Product Description, and they should submit their white papers by May 12, 2025, with further evaluations and demonstrations scheduled for late May 2025. For inquiries, vendors can contact Eric Roberts at eric.j.roberts48.civ@army.mil or Michael Kelly at michael.j.kelly99.civ@army.mil.
