PARIS, Sept. 15, 2026 /PRNewswire/ — HawkEye 360 (NYSE: HAWK), the global leader in signals intelligence data and analytics, today announced a strategic collaboration with ERA a.s., a leading provider of multistatic passive surveillance and tracking technologies. Under the collaboration, ERA will work alongside HawkEye 360 as an international processing partner for automated terrestrial and maritime radar products derived from HawkEye 360’s radio frequency (RF) data.

The partnership brings together the companies’ complementary strengths to deliver faster, more efficient, access to mission‑relevant RF insights. By combining HawkEye 360’s space‑based signals intelligence, automated geolocation, and advanced RF analytics with ERA’s integration and mission‑workflow capabilities, the collaboration significantly enhances HawkEye 360’s ability to provide defense and security customers with timely, operationally actionable information.

This partnership expands access to HawkEye 360’s high‑value RF data and analytics, enabling customers to move RF‑derived insights more quickly and seamlessly into operational environments. Together, the companies will help streamline mission workflows, strengthen situational awareness, and empower users to make faster, better‑informed decisions across a range of demanding operational scenarios.

“European defense organizations are seeking faster, more integrated ways to understand increasingly complex operating environments,” said John Serafini, Chief Executive Officer of HawkEye 360. “By combining HawkEye 360’s space-based signals intelligence with ERA’s automation and processing expertise, we can deliver actionable information more quickly to support allied warfighters and defense leaders across Europe.”

“We are pleased to see our cooperation with HawkEye 360 advancing to a whole new level,” said ERA CEO Ondřej Chlost. “We are seeing growing customer interest worldwide—not only in advanced passive surveillance systems and their role in modern defense concepts, particularly in SIGINT, but also in integrating existing solutions already deployed in the field to unlock new capabilities.”

The agreement reflects a shared commitment to advancing defense and surveillance capabilities through innovation. By uniting their technologies and expertise, HawkEye 360 and ERA will provide customers with enhanced capability to transform RF data into operationally useful information while improving the speed and efficiency of decision-making.
