The Ground Based RADAR Digitization (GBRD) program seeks to modernize six radar sites to improve space domain awareness, address sustainment challenges, and enhance radar performance. This initiative supports the National Defense Strategy by improving missile warning, defense, and tracking capabilities. Key objectives include digitizing analog radar systems for better tracking and EMI rejection, implementing modular open system architectures for future upgrades and reduced sustainment costs, ensuring cybersecurity compliance, and incorporating developed digital receiver technology. The program also focuses on sustainment strategies to reduce lifecycle costs and manage material shortages, as well as innovative contracting approaches to accelerate execution and engage non-traditional defense contractors. The USSF is seeking industry input on technical capabilities, sustainment strategies, contracting approaches, and industry collaboration, including leveraging commercial off-the-shelf (COTS) technologies.

The FA872325RB003 Request for Information (RFI) for GBRD (Ground-Based Radar Modernization) is a new requirement seeking industry input for modernizing the USSF's Space Domain Awareness and Missile Warning/Defense capabilities. The government aims to improve Space Domain Awareness of Ground-Based Radars, continue missile warning/track/defense operations, and reduce future sustainment costs through open architecture, commercial off-the-shelf solutions, and a common baseline. Funding is contingent on program priorities and budget allocations. The USSF is open to participation from traditional and non-traditional defense contractors, small businesses, and educational institutions. Key aspects include the use of OTAs, MTAs, and FAR-based contracts (for which industry input on types and numbers is sought), and the modernization scope begins after the antenna array face, including beam steering, with specific antenna elements excluded. A Secret clearance is required for on-site integration. The government has a digital receiver technology (TRL-7, TRL-9 by October 2025) which meets or exceeds current system performance. All available documentation, including technical data packages, will be provided in a Bidder's Library along with the Request for Solution.

The U.S. Space Force (USSF) is hosting an Industry Day on December 11, 2025, at Cape Cod Space Force Station to discuss the Ground Based Radar Digitization (GBRD) program. This initiative aims to modernize six radar sites (five Upgraded Early Warning Radars and one Perimeter Acquisition Radar Attack Characterization System) to enhance missile warning, missile defense, missile tracking, and space domain awareness capabilities. The USSF seeks industry input on solutions that leverage open-system, non-proprietary architectures, utilize Commercial Off-The-Shelf (COTS) technology, and incorporate existing digital receiver technology. The event will foster synergy between the USSF and industry, allowing for feedback on requirements and sharing program details. Attendees must RSVP by December 4, 2025, possess a US Government Secret Clearance, and adhere to strict site access requirements, including a one-representative-per-company limit.
