THIS IS A REQUEST FOR INFORMATION (RFI) ONLY. This RFI is issued solely for information and planning purposes. It does not constitute a solicitation or a promise to issue a solicitation in the future. This request for information does not commit the Government to contract for any supply or service. Further, the Government is not seeking proposals and will not accept unsolicited proposals. Respondents are advised that the Government will not pay for any information or administrative costs incurred in response to this RFI; all costs associated with responding to this RFI will be solely at the interested party s expense. Not responding to this RFI does not preclude participation in any future solicitation, if any is issued. It is the responsibility of the vendor who is interested in any potential future solicitation(s) to monitor all sites for additional information pertaining to this requirement.

Respondents are advised that the Government is under no obligation to acknowledge receipt of the information received or provide feedback. The Government reserves the right to use results of communications with industry for any purpose consistent with, and not otherwise prohibited by FAR Part 10. 1. Purpose. United States Space Force (USSF) is seeking information from industry regarding the modernization of Ground Based Radars (GBR) under GBRD. This effort aims to digitize legacy radar systems to enhance battlespace situational awareness, reduce sustainment costs, and address obsolescence issues. The USSF is particularly interested in solutions that: Leverage open system, non-proprietary architectures to ensure future scalability and avoid vendor lock. Utilize Commercial Off-The-Shelf (COTS) technology to minimize development risks and costs. Incorporate existing, developed digital receiver technology as the baseline receiver for the system (data package will be provided later). The acquisition strategy for this program is still under development but is considering the following approach: Middle Tier Acquisition (MTA) pathway to accelerate program execution. Other Transaction Authority (OTA) for prototyping the first two sites [1x Upgraded Early Warning Radar (UEWR) and Perimeter Acquisition Radar Attack Characherization System (PARCS)]. A follow-on production contract for the remaining four UEWR sites. This RFI is intended to: Identify innovative solutions for radar digitization and modernization. Explore contracting approaches to support the proposed acquisition strategy. Assess industry capabilities to meet program objectives within the required timeline and budget Determine industry willingness and ability to provide government owned, non-proprietary, and COTS based designs 2. Background. The GBR modernization effort supports the National Defense Strategy by continuing missile warning (MW), missile defense (MD), missile tracking (MT), and improving space domain awareness (SDA) capabilities. The program will: Digitize six radar sites (5x UEWR, 1x PARCS) to improve space domain awareness capabilities and address sustainment challenges and obsolescence. Enhance radar performance, including increased tracking capacity, extended range, and improved object classification. Transition to a government-owned, modular open system architecture with a high level of commonality between UEWR and PARCS back ends The front end, high power Radio Frequency (RF) components will be retained as well as the communications paths out of the radars Key Program Details: Initial Operational Capability (IOC): 2028 (UEWR Site), 2029 (PARCS). Full Operational Capability (FOC): 2030 (6 sites). 3. Objectives. The USSF seeks industry input on the following areas: Technical Capabilities: Solutions for digitizing analog radar systems to improve tracking, classification, and electromagnetic interference (EMI) rejection Modular open system architectures to enable future upgrades and reduce sustainment costs Cybersecurity compliance for modernized radar systems Incorporation of developed digital receiver technology as the baseline receiver for the system Sustainment Strategies: Approaches to reduce lifecycle sustainment costs and address diminishing manufacturing sources and material shortages (DMSMS). Strategies for transitioning from legacy systems to modern architectures while minimizing radar down time required Contracting Approaches: Recommendations for leveraging MTA and OTA pathways to accelerate program execution Innovative contracting mechanisms to engage non-traditional defense contractors (including academia and small business concerns) Industry Collaboration: Opportunities for partnerships/teaming with non-traditional defense contractors (including academia and small business concerns) Insights into leveraging commercial off-the-shelf (COTS) technologies to minimize development risks and buy commercial solutions 4.

The U.S. Space Force is modernizing critical missile defense radars, including five Upgraded Early Warning Radars (UEWR) and the Perimeter Acquisition Radar Attack Characterization System (PARCS), through the Ground-Based Radar Digitization (GBRD) Program. These aging systems are nearing obsolescence, necessitating technological upgrades. GBRD aims to digitize these radars for enhanced battlespace awareness, reduced sustainment costs, and resolution of obsolescence challenges. Using a Middle Tier Acquisition (MTA) Rapid Prototyping acquisition pathway approach, GBRD will first prototype solutions at two sites (one UEWR and PARCS) before proceeding with Rapid Fielding production for the remaining UEWR locations. This strategy enables agile development and rapid deployment of modernized capabilities. This modernization improves radar weapon system effectiveness and efficiency through commonality, sustainable support, and optimized human interaction, including a digital ecosystem, modular design, and a common baseline. In addition, with collaboration with MDA, MD capability at PARCS will be added. GBRD leverages advanced technologies like digital engineering, DevSecOps, and open systems architecture to ensure rapid delivery. A near-common automation platform will replace disparate operating systems, address inefficiencies and enhance interoperability between the MW, MD, and SDA missions. Ultimately, GBRD will overcome current UEWR and PARCS limitations like lack of automation, inflexible design, and high maintenance costs, enabling improved data integration, accelerated deployment, stronger cybersecurity, and enhanced adaptability to evolving threats. By systematically integrating data-driven insight capabilities, the GBRD aims to transform its vast data repositories into actionable intelligence, enabling proactive responses to emerging threats and optimizing resource allocations. This strategic adoption will ensure that the radars remain agile, resilient, and ahead of adversaries in a rapidly evolving space based operating environment.
