Northrop Grumman and U.S. Space Force Space Systems Command's Deep-Space Advanced Radar Capability (DARC) have successfully linked multiple ground-based antennas at Site 1 in Western Australia, marking a first for the program and advancing efforts to build the most capable deep-space tracking radar system in the world.

The calibrated antenna arrays operated as a unified system, enabling precise tracking of multiple satellites. This milestone brings Site 1 closer to completion and full operational readiness. The trial involved using seven of the site's 27 antennas, proving technology designed to monitor spacecraft that may pose risks to U.S. and allied assets.

Over several weeks, the team conducted data collection, analysis, and calibration to validate operational performance. DARC is a t
