The Honeywell RDR-4000M is a state-of-the-art, 3D weather radar system tailored specifically for military applications, derived from Honeywell’s proven IntuVue™ commercial radar technology. Designed to deliver unmatched reliability, situational awareness, and mission adaptability, the RDR-4000M integrates advanced weather detection with high-resolution ground mapping and predictive hazard capabilities, ensuring optimal performance in both routine and combat flight environments.
Honeywell RDR-4000M
High-Performance 3D Scanning and Ground Mapping
The RDR-4000M utilizes 3D volumetric scanning and pulse compression technology to provide a comprehensive weather and terrain view from 0 to 60,000 feet, covering a range up to 320 nautical miles. Its automated weather detection system allows continuous hazard assessment without the need for manual tilt adjustments, thereby reducing pilot workload. The radar supports multiple military-specific modes including High-Resolution Ground Mapping (HRGM), Precision Ground Mapping (PGM) with Doppler beam sharpening, and skin paint modes for formation flying and aerial refueling. These capabilities enable pilots to identify turbulence, hail, lightning, and areas of beam attenuation with remarkable clarity, aiding in safer flight route planning and enhanced operational execution.
Reliable, Compact Design with Advanced Military Features
Built with a solid-state transmitter and DC brushless direct drive, the RDR-4000M offers an impressive Mean Time Between Failure (MTBF) of 8,000 hours, significantly lowering operational and maintenance costs compared to older radar systems. Its lightweight architecture reduces system-installed weight by up to 65% over legacy military weather radars. Enhanced with REACT technology (Rain Echo Attenuation Compensation Technique) and predictive alerts for turbulence, hail, and lightning, the radar ensures advanced hazard detection. With support for NVG-compatible controls and silent emissions operation, it is ideally suited for tactical and transport aircraft like the C-130 Hercules, C-17 Globemaster, and Japan’s C-X transport.
