Army Seeks Digital IF Systems for Up to 20 Global SATCOM Sites

The U.S. Army, through Army Contracting Command – Aberdeen Proving Ground (ACC-APG), posted a Commercial Solution Opening (CSO) Call for Solutions on October 29 for Product Manager Wideband Enterprise Satellite Systems (PdM WESS). The effort is part of Increment 1 of a modernization initiative seeking a commercial-off-the-shelf (COTS) Digital Intermediate Frequency (Digital IF) system. Responses are due by 12:00 p.m. Eastern on December 10, 2026. The Army’s requirement combines equipment with deployment services: the selected vendor is expected to deliver, integrate, install, and acceptance-test the solution at as many as 20 worldwide satellite communications (SATCOM) teleport sites.

The procurement addresses limitations in the Department of War’s existing SATCOM ground infrastructure, which the source describes as relying heavily on legacy L-Band IF distribution systems. Analog, hardware-bound architectures can constrain scalability, resilience, and interoperability, inhibit rapid technology insertion, and create single points of failure across geographically dispersed teleport infrastructure. The Army is therefore looking for a flexible, open-standard, modular Digital IF capability set rather than a site-specific replacement that would perpetuate those constraints. The solicitation cites Digital Intermediate Frequency Interoperability compliance as an example of the open-standard approach sought.

Increment 1 is intended to establish a fully operational baseline that can support later capability upgrades and integrations in future fiscal years. This makes the initial configuration and its interoperability characteristics important beyond the first deployment: vendors should consider how their proposed architecture can serve as a repeatable standard across sites and accommodate subsequent technical changes. The source says the selected solution will undergo standard site acceptance testing and operational verification to confirm contract performance requirements and compatibility with each site. After successful acceptance, the validated configuration will provide the baseline for deployment and installation across the planned global footprint.

For prospective respondents, the opportunity calls for more than a Digital IF product. Firms should evaluate whether they can provide the commercial system alongside the integration, installation, and acceptance-testing capacity required for a multi-site deployment. The Army frames the operational objective as more resilient, agile, and rapidly scalable SATCOM that can adapt to contested and congested environments and support warfighter lethality and survivability. Companies should review the CSO on SAM.gov, map their proposed solution to the stated requirements and response instructions, and account for site compatibility and verification in their submission. The source does not provide an estimated contract value, award date, or named incumbent, so interested firms should use the solicitation for authoritative scope and submission details.

• The U.S. Army released the CSO on October 29, 2026, through ACC-APG for PdM WESS.
• Responses are due December 10, 2026, at 12:00 p.m. Eastern.
• The requirement is for a COTS Digital IF system supporting Increment 1 of a SATCOM modernization effort.
• The selected vendor will deliver, integrate, install, and acceptance-test the system across up to 20 worldwide SATCOM teleport sites.
• The target architecture is flexible, modular, and open-standard; the source gives Digital Intermediate Frequency Interoperability compliance as an example.
• Legacy L-Band IF infrastructure is described as limiting scalability, resilience, interoperability, and rapid technology insertion.
• Site acceptance testing and operational verification will assess performance requirements and site compatibility.
• Increment 1 establishes a baseline for later upgrades and integrations in future fiscal years.
• Respondents should assess both product fit and their capacity to execute integration, installation, and testing across multiple international sites.
• No contract value or award date is provided in the source; firms should consult the SAM.gov CSO for the controlling requirements and response instructions.
