IN Brief:
- A Rafale F4 controlled a NAMIB-equipped uncrewed aircraft during a collaborative electronic-warfare flight.
- The payload detected and geolocated a radar before transferring targeting information to the fighter.
- Production will require repeatable RF hardware, secure datalinks, calibrated antennas, software assurance, and adaptable airframe interfaces.
Dassault Aviation and Harmattan AI have completed a collaborative flight in which a Rafale F4 controlled an uncrewed aircraft carrying the newly developed NAMIB electronic-warfare payload.
During the demonstration, the uncrewed platform detected and geolocated a radar several dozen kilometres away before transmitting its position to the Rafale. The fighter crew then used that information during a simulated engagement.
NAMIB is designed to detect, identify, and locate electromagnetic emissions, including those produced by air-defence radars. Its architecture allows the payload to be installed on different classes of uncrewed aircraft, from tactical multicopters to fixed-wing platforms offering greater range and endurance.
A reusable payload across several carriers would allow forces to select an aircraft according to mission risk and distance. A relatively inexpensive multicopter could operate close to friendly positions, while a fixed-wing system might carry the same sensing package farther into defended airspace.
Compact electronic-warfare equipment is difficult to produce well. Sensitive receivers, antennas, processors, navigation equipment, power conversion, cooling, and secure communications must fit within a small mass and volume allowance while remaining isolated from the electromagnetic noise generated by the host aircraft.
Emitter geolocation also depends on precise calibration. The payload needs accurate knowledge of its own position, orientation, timing, antenna characteristics, and platform movement. Reflections from terrain, overlapping transmissions, intermittent emissions, and deliberate deception can all reduce confidence in the solution.
Production variation therefore affects operational performance. Changes in antenna installation, shielding, cable routing, connector quality, or thermal behaviour may alter receiver sensitivity or create false signals, even when two completed units contain the same nominal components.
Automated test equipment will need to reproduce a broad range of radar emissions and check each payload across frequency, power, direction, and temperature conditions. Calibration records should remain tied to individual units so that drift or repair work can be identified throughout service.
The collaborative flight added another layer of integration by transferring the target information into the Rafale’s mission system. Data had to arrive in a usable format, with enough confidence and timeliness for the crew to assess it and include it within the tactical picture.
Rafale F4 provides a more connected architecture than earlier standards, supporting data exchange among aircraft, sensors, weapons, and command systems. NAMIB uses that foundation to extend the fighter’s electronic horizon without requiring the crewed aircraft to approach every emitter itself.
Dassault and Harmattan began developing the payload in January 2026, compressing initial design, integration, and flight work into a short period. Further qualification will be more methodical, covering vibration, temperature, humidity, electromagnetic compatibility, cybersecurity, flight safety, and repeatable performance across production hardware.
Radio-frequency supply chains can become a bottleneck quickly. Specialist amplifiers, converters, processors, high-speed data devices, antennas, and packaging technologies serve radar, communications, missiles, satellites, and electronic-warfare programmes simultaneously, while export controls restrict some sources.
Airframe integration introduces different constraints for every carrier. A multicopter produces vibration and rotor interference, offers limited endurance, and may provide little cooling. A fixed-wing aircraft changes antenna fields of view, power availability, datalink range, recovery method, and structural loads.
Common mechanical, electrical, and software interfaces can limit the number of bespoke variants, although full interchangeability is unlikely. Interface kits may need different antenna arrangements, power conditioning, mounts, and cooling equipment while retaining the same core receiver and processor.
Collaborative combat-air development is increasingly divided between purpose-built uncrewed aircraft and modular payloads installed on smaller platforms. Australia’s Ghost Bat programme represents the larger end of that spectrum, combining substantial range and payload capacity with crewed–uncrewed operations.
NAMIB approaches the same networked force from the mission-system level. Some aircraft may carry weapons, whereas others provide electronic support, communications relay, jamming, decoys, or surveillance. Standardised payloads would allow those roles to change without procuring a separate aircraft for every function.
Such flexibility transfers complexity into configuration management. Payload software, aircraft control systems, datalinks, ground stations, Rafale mission systems, and threat libraries will evolve on different schedules. Each release must remain compatible with the others, particularly when several aircraft cooperate within the same engagement.
Threat libraries also require controlled and secure production processes. Electronic-warfare equipment depends on detailed descriptions of radar behaviour, signal characteristics, and likely operating modes. Protecting that data, distributing updates, and confirming that every deployed payload uses the correct baseline are continuing support tasks.
Communications cannot be assumed to remain available. NAMIB-equipped aircraft will need enough onboard processing to continue collecting and classifying signals when links are degraded, while the wider system must authenticate data and reject attempts to inject false positions or commands.
The ability to expose an uncrewed aircraft rather than a Rafale supports suppression and destruction of enemy air defences, although the economics depend on the carrier. A low-cost platform can be risked more readily, but only if payload cost, range, signature, and replacement rate remain compatible with attritable operations.
Follow-on trials will need more complex emitter environments, several cooperating aircraft, degraded navigation, jamming, and integration on additional carriers. They should also establish how rapidly threat-library and software updates can move from analysis into operational systems without interrupting fleet availability.
The flight has provided a credible demonstration of radar detection and collaborative targeting. Industrial progress will be measured by whether NAMIB can be produced consistently, calibrated efficiently, and integrated across several airframes without allowing each installation to become another bespoke electronic-warfare programme.
