The Department of Defense, specifically the Army Contracting Command, is conducting a market research effort to identify potential prime contractors for the sustainment of the Modi FamilFoS system, an electronic warfare support solution for U.S. forces. The government seeks parties capable of providing maintenance services, procurement of spare parts, and support for both mounted and dismounted systems to ensure the sustained operational effectiveness of the Modi system. This initiative is crucial as the Modi system enables soldiers to navigate the electromagnetic spectrum effectively by deploying electronic countermeasures, although complete technical documentation remains proprietary to the original equipment manufacturer. Interested respondents are invited to submit unclassified white papers detailing their corporate capabilities and experience by 14 March 2025, with primary contact Patrick Cruickshank available at patrick.r.cruickshank.civ@mail.mil for further inquiries.
