A Game-Changer in Space Surveillance

In a groundbreaking achievement, the Space Force's deep-space radar program has hit a critical testing milestone, successfully utilizing seven antennas to track multiple satellites orbiting Earth from a site in Australia. This marks a pivotal step in enhancing space surveillance.

Introducing DARC: The Future of Satellite Tracking

Enter the Deep Space Advanced Radar Capability (DARC), a state-of-the-art system being developed by Northrop Grumman designed to detect and monitor a range of activities in geosynchronous orbit. From tracking space debris to detecting potentially hostile movements that could jeopardize U.S. satellites, DARC represents a significant leap in space defense technology.

Countdown to Full Operational Capabilities by 2027

Slated to be fully operational by 2027, DARC is the first of three radar systems being established in partnership with Australia and the United Kingdom, aimed at bolstering visibility and tracking capabilities in the vast expanse of outer space.

Successful Demonstration Signals a Step Forward

The recent successful demonstration showcases DARC’s integration and testing phase, which began just weeks ago. Ultimately, this ground-based system will utilize a total of 27 parabolic antennas for deep-space surveillance, creating a highly sophisticated radar network. According to Kevin Giammo, Northrop’s director of space surveillance, even the preliminary setup with seven antennas indicates the design's robustness and scalability.

Innovative Array Technology Enhances Detection Capabilities

Giammo explains, “Each of these parabolic dishes possesses significant individual capabilities; however, when combined into an array, they produce the power of a much larger radar system with enhanced functionalities.” As testing progresses, the plan is to incrementally increase the number of antennas engaged, further refining the precision and duration of their observations.

Expansion of the DARC Program with International Collaboration

In addition to the Australian installation, Northrop Grumman is making headway in developing the second radar system, which will be positioned in the United Kingdom. A $200 million contract for DARC 2 was awarded last year, and the Space Force continues to work closely with the U.K. government on essential environmental assessments required before construction can commence.

Adapting to Unique Challenges for International Deployment

As Northrop embarks on this journey, leveraging learnings from the first radar is paramount. Giammo notes that design distinctions may arise as each radar is tailored to its geographical location. “Given that we are fielding similar systems in different sites, each will have its unique attributes,” he emphasized.

Funding Prospects Amid Budget Constraints

It's notable that the Space Force's fiscal 2026 budget request does not currently include explicit funding for the DARC program. However, it plans to tap into $281 million allocated from Congress’s substantial reconciliation bill, ensuring ongoing progress and development.
