L3Harris displayed a new and improved version of its Diamondback reconnaissance and security unmanned ground vehicle (UGV) at the 2025 Association of the US Army (AUSA) show, held in Washington, DC, from 13 to 15 October.
The vehicle was originally shown for the first time at AUSA in 2024, but is now very much a working prototype as opposed to a concept model.
Developed through a partnership with Carnegie Robotics, the Diamondback UGV is based on the chassis of the Polaris MRZR ultra-light tactical vehicle, but is controlled using L3Harris’ Autonomous Multi-domain Operations Resiliency Platform for Heterogeneous Unmanned Swarms (AMORPHOUS) autonomy software. The Diamondback can thus operate autonomously as part of a wider fleet of similarly autonomous assets.
Described by L3Harris as a scalable, cost-effective, and highly mobile autonomous ground vehicle for around-the-clock reconnaissance and security operations, the Diamondback UGV features LiDAR sensors front and rear and a Wescam MX-series opto-electronic turret on top of the front of the vehicle (which strangely makes it look like a helmeted figure is driving it).
The Diamondback can be controlled out to ranges of 15-20 km using L3Harris’ Wraith jam-proof radio waveform, but also features a Starlink terminal for control via satellite communications.
The Diamondback UGV shown at AUSA 2025 was integrated with three internally housed rotary-wing tactical unmanned aerial vehicles to expand the platform’s autonomous reconnaissance capabilities.
An L3Harris spokesperson told ESD at AUSA 2025 that the Diamondback UGV is now ready to start booking orders.
