Himera SDR

Himera’s tactical radios emerged from the same crucible that has shaped much of Ukraine’s recent defence-industrial output: the demand for cheap, software-defined communications gear that can keep working when Russian electronic warfare has saturated the frontline RF environment. The company, founded in 2022 by a small team of Ukrainian engineers, shipped its first units to forces in the field in 2023 and has iterated steadily since. The flagship product, the G1 Pro handheld, is positioned as a low-cost alternative to the high-end NATO tactical radios — Harris, Thales, and similar — that most Ukrainian platoons cannot afford in the numbers they need.

The G1 Pro is a software-defined radio built around frequency-hopping spread spectrum in the sub-gigahertz band, with AES-256 encryption layered over the air interface and a mesh-style topology that lets units relay through each other rather than depending on a central node. Effective range sits in the low single-digit kilometres in open terrain and contracts in dense urban environments, which matches the squad-to-squad and squad-to-platoon traffic the device is built for. Hopping patterns and waveform parameters can be reconfigured in software, so a unit that finds its frequencies being jammed can roll to a new pattern without swapping hardware. The ruggedised case, replaceable battery, and a unit price reported in the low-hundreds of dollars — against Western equivalents that often clear five thousand — are the practical levers that have driven adoption at scale.

Ukrainian forces are the primary operators, with the radios in use across infantry brigades, drone teams, and territorial defence units. Himera does not publish deployment counts, but the company has said its devices are in the field in the thousands. Demonstrations at SOF Week and other Western defence events have drawn attention from US and European special operations communities, who have been looking closely at what affordable, jam-resistant comms might look like outside the traditional defence-prime supply chain.

Development since 2023 has focused on extending range, reducing power draw, and adding network-management features for larger formations. The G1 Pro is one of several Ukrainian-built communications systems that have grown directly out of the wartime requirement to operate inside a contested electromagnetic spectrum, and it has become a reference point for what a wartime, software-first tactical-radio programme can deliver when the procurement cycle is measured in months rather than years.
