On Tuesday, 18 November 2025, the U.S. company Elsight announced that it had received a contract from the Defense Innovation Unit (DIU), a research arm of the U.S. Department of Defense, to supply Halo communication modules for unmanned systems as part of Phase III of Project G.I. for reference mission No. 2.

This selection follows Elsight’s successful results in Phase II, during which the company demonstrated its Halo multi-link communication platform as a key enabler for creating mission-ready unmanned systems that support successful tactical operations in environments with electromagnetic interference and electronic warfare (EW).
Elsight’s HALO system impressed U.S. Department of Defense testers during personnel training and demonstrations, showing how multi-link, distributed data connectivity can significantly enhance operational effectiveness, improving both striking power and survivability in complex environments, including resistance to jamming and other forms of electronic warfare.
Based on these achievements, the DIU research unit invited Elsight to participate in Phase III, simultaneously awarding funding to support the company’s continued participation and demonstration activities. An additional contract for completing Phase II will be granted together with the initial funding for Phase III. Under Phase III, Elsight will continue to demonstrate and validate the operational readiness of its Halo system in real-world scenarios.
“We’re honored to continue working with the Defense Innovation Unit and our U.S. DOW partners,” said Yoav Amitai, CEO of Elsight. “Our HALO platform has been designed to deliver resilient, secured, and portable connectivity that modern uncrewed systems demand. Advancing to Phase 3 underscores our shared commitment to empowering tactical defense operations with persistent, mission-critical communications, ready to scale to meet DOW’s production requirements.”
Elsight’s innovative communication platform, Halo, uses multi-link aggregation to provide continuous coverage by seamlessly combining all available communication channels (4G/5G SA and NSA cellular networks, SATCOM, and local P2P/RF radio networks) into a single, secure communication tunnel. This unified, spectrum-aware technology ensures uninterrupted command and real-time data transmission, even in electromagnetically contested environments. At Technology Readiness Level 9 (TRL 9), Halo is device-agnostic, integrating smoothly with leading Blue-class unmanned aerial system models.
“This milestone holds pivotal significance. It validates both Halo’s effectiveness in ensuring persistent connectivity while showcasing our readiness to scale production to thousands of units to meet DOW’s demands. We are fully prepared for this next stage,” stated Amitai.
