The U.S. Army is conducting market research to identify mature commercial software for a unified communications platform that integrates tactical voice systems, including radios, telephony, and IP devices. The software must provide real-time collaboration tools, advanced analytics, end-to-end encryption, and operate in closed, multicast-reliant environments without needing a centralized service. The goal is to support deployments from small teams to corps-level, with a required operational capability by the third or fourth quarter of Fiscal Year 2026. The Army intends to procure annual software licenses directly from OEMs. Interested vendors with a qualifying solution should submit a tailored capability statement and company information to the provided Point of Contact.
