Comprehensive Overhaul of Radar Systems
The United States Space Force is undertaking a significant expansion of its Ground Based Radar Digitization (GBRD) initiative, aimed at modernizing its aging ground-based radar systems. This effort will encompass all eight existing radars, transitioning from outdated analog technology to a fully digitized infrastructure. The initiative is designed to enhance missile defense and space monitoring capabilities, addressing the challenges posed by modern digital threats, which include smaller, faster, and more numerous objects.
Details of the Modernization Plan
The GBRD program will replace a previously narrower plan that focused on upgrading only six radars with partial subsystem enhancements. The current scope includes the Upgraded Early Warning Radars (UEWRs) located at Beale Air Force Base in California, Fylingdales in the United Kingdom, and Thule Air Force Base in Greenland, as well as the Perimeter Acquisition Radar Characterization System (PARCS) in North Dakota, the Cobra Dane radar in Alaska, and the AN/FPS-85 radar at Eglin Air Force Base in Florida. The modernization will involve equipping all radars with a unified "back end" of computers, servers, and software, alongside updated "front end" antennas. This approach aims to standardize operations across the radar fleet, allowing for a more cohesive and efficient data processing system.
Implications for Missile Defense
The upgraded systems are expected to significantly improve the Space Force's ability to monitor space and provide missile warning data. The PARCS radar, operational since the 1970s, and the Cobra Dane radar, which supports the North American Aerospace Defense Command, will benefit from these enhancements. The AN/FPS-85 radar, capable of tracking up to 200 satellites simultaneously, will also see improvements that will enhance its operational capabilities.
Timeline and Vendor Participation
The Space Force plans to achieve initial operational capability with four "Rapid Prototype" sites by the first quarter of fiscal year 2030, with full operational capability anticipated by the second quarter of fiscal year 2031. Vendors interested in participating in the GBRD initiative have until April 1 to respond to the revised request for information (RFI).
Criticism & Opposition
While the modernization effort has been generally well-received, some critics have raised concerns about the pace and funding of the initiative. Questions remain regarding the allocation of the $1.98 billion earmarked for improved ground-based missile defense radar systems in the Pentagon’s fiscal 2026 reconciliation package, with some stakeholders advocating for clearer communication on funding sources and timelines.
