Latest Satellite Cluster Expands Capacity for Global RF Signals Intelligence

The three formation-flying satellites, launched on June 26 (ET) aboard a Rocket Lab Electron rocket, are now fully calibrated, commissioned, and integrated into HawkEye 360’s constellation — delivering mission-ready signals intelligence across key global regions.

The mission also included Kestrel-0A, an experimental satellite designed to evaluate emerging capabilities that inform HawkEye 360’s next generation of technologies. Kestrel-0A is progressing well, with ongoing contact and early-stage mission milestones being achieved.

“Achieving FOC for Cluster 12 strengthens our ability to deliver timely, mission-critical signals intelligence to defense, intelligence, and commercial partners,” said Todd Probert, President, U.S. Government. “This cluster enhances our ability to monitor complex operating environments, detect signals of interest, and drive informed decisions across land and sea.”

Cluster 12 adds further depth and coverage to HawkEye 360’s constellation, supporting expanded frequency detection, improved revisit rates, and broader global reach. These advancements directly support the growing demand for signals intelligence to address challenges such as maritime domain awareness, air defense system detection, and GNSS interference monitoring.
