The system

Counter-UAS in the palm of your hand.

Designed to be carried as a routine secondary item, not allocated to one specialist and shared by the rest of the squad.

RAKURAI is a dismounted electronic countermeasure system for small unmanned aircraft. It is designed to disrupt the control, navigation and data links hostile platforms rely on before the threat is overhead.

The platform can be fielded as a complete C-UAS system or used as a programmable development platform for primes, OEMs and integrators building proprietary signals and software on MILLIBEAM RF hardware.

400 MHz–6 GHz

Wideband coverage

Coverage spanning ISM, GNSS and Wi-Fi-dependent control, navigation and data links.

One hand

Operator fit

Designed for use while the Soldier retains access to a primary weapon or other equipment.

>2 hours

Measured endurance basis

More than two hours with all bands active under continuous transmission, not standby.

SDK in development

Programmable platform status

The programmable signal layer is being developed for partner-created waveforms, operating modes and software-layer IP.

The squad-level capability gap

Doctrine says every Soldier. Hardware still says specialist.

Current handheld systems force units to concentrate protection in one operator or fire team, the opposite of what dispersed operations require.

“Countering small unmanned aircraft is the responsibility of every Soldier and unit.”US Army ATP 3-01.81 · Counter-UAS

Typical handheld category

Every-Soldier requirement

2–7 kg on top of weapon, plates, ammunition and water

Under 1 kg

Less than one hour at full duty

Multiple hours continuously

Narrow ISM and GNSS coverage

Military and civilian-threat links

Two-handed, aimed operation

One-handed operation

Dedicated, trained specialist

Basic familiarisation

A dispersed patrol, building-clearance team or defensive position cannot rely on one specialist always being in the right place, with line of sight, when the UAS appears.

The differentiator

It is not one number. It is the combination.

Handheld jammers exist. Multi-band jammers exist. Multi-hour systems exist. No one has put all three in one hand. What changes the operational and procurement calculus is achieving the full combination in one envelope, small enough, persistent enough and capable enough for general issue.

GENERAL-ISSUE CAPABILITYThe full operating envelope in one handheld system

What it disrupts

Target the links the aircraft depends on.

RAKURAI is designed around the signal pathways that enable reconnaissance, navigation, command and terminal attack.

Command

Disrupts control links between the aircraft and operator, reducing the operator’s ability to manoeuvre or prosecute a target.

Navigation

Denies GNSS inputs used to reach, navigate toward or hold a target across supported satellite-navigation services.

Video & data

Disrupts links used for live imaging, reconnaissance, situational awareness and terminal guidance.

Operational fit

Protection that moves with the formation.

The platform is designed for distributed use across dismounted, mobile and fixed-site operating contexts.

Representative small unmanned aircraft threat

01 · Dismounted patrol

Coverage moves with the Soldier.

Protection remains organic to dispersed patrol elements rather than being concentrated in one specialist position.

02 · Fixed-site perimeter

Every observation point carries capability.

Guard positions and dispersed perimeter elements can hold local protection without waiting for a central team.

03 · Vehicles & small craft

Handheld where larger systems do not fit.

A compact option for convoy, patrol-vessel and small-platform contexts where vehicle-mounted architectures are impractical.

Why the envelope is possible

The specification is a systems-engineering result.

RAKURAI is not a collection of catalogue parts assembled inside an enclosure. The antennas, RF front end, power system, signal chain, thermal design and mechanics are engineered against one mission envelope by one team.

That vertical integration allows each layer to be optimised for the actual operating conditions of the device instead of the fixed design points of general-purpose components.

System-specific antennas

Radiation efficiency, gain pattern, feed structures and enclosure interaction designed together.

GaN RF power amplifiers

Power, efficiency, bandwidth, supply range and thermal behaviour engineered for the handheld duty profile.

Power electronics

Battery management, conversion, sequencing and protection designed to preserve operating time.

Signal generation

Programmable operation across bands, modes and partner-developed software.

Mechanical, thermal & EMI integration

Enclosure, antenna placement, thermal paths and electromagnetic interactions resolved from the start.
