Arkeus has confirmed that its Warden Hyperspectral Optical Radar will enter service with the Australian Army, providing wide-area domain awareness for the Integrator uncrewed aerial system (UAS) under the Tactical Uncrewed Aerial System (TUAS) Program. The capability is intended to strengthen the Army's ability to detect, understand, and respond across land and littoral environments. The announcement follows a competitive selection process completed in November 2025 and successful integration, testing, and validation with the Australian Army and Insitu Pacific.
Advanced Sensing for Tactical Operations
The Warden HSOR is described by Arkeus as the world's first real time, wide-area, hyperspectral intelligence, surveillance, and reconnaissance sensor designed for tactical uncrewed aircraft systems. Unlike conventional sensing hardware built for human operators, Warden is specifically engineered for artificial intelligence and is not constrained by human limitations. Its hyperspectral optical radar can see significantly further than comparable alternatives, according to the company.
Integration with the Integrator UAS
Warden will be mounted on Insitu Pacific's Integrator Uncrewed Aerial Systems. Arkeus has collaborated with Insitu Pacific for several years to enhance domain awareness for the Integrator Air Vehicles. Andrew Duggan, Managing Director of Insitu Pacific, said the Integrator's range, endurance, and mission flexibility make it well suited to persistent surveillance across land and maritime environments.
AI Powered Detection and Decision Support
The sensor uses Arkeus' ARK artificial intelligence orchestration and data fusion software, which operates at the edge on the sensor itself. This allows the system to autonomously detect, classify, locate, and track objects in real time over wide areas. According to Arkeus, Warden extends the area of coverage from each platform in land, littoral, and maritime domains and provides a disruptive speed and precision of decision making.
Army Leadership Perspective
COL Joel Domigan from Headquarters Army Aviation Command said the acquisition is part of the Australian Army's TUAS Program to support tactical level intelligence, surveillance, and reconnaissance requirements of Army's Combat Brigades. He stated that Warden enhances the Army's ISR posture by providing persistent, wide-area surveillance from the Integrator platform. The capability enables commanders to extend situational awareness, shorten decision cycles, and maintain operational advantage across land and littoral domains.
Performance in Complex Environments
During testing and integration, Warden demonstrated an ability to perform in challenging and degraded conditions, by day and night, where conventional optical systems can struggle. Simon Olsen, Arkeus CEO and co-founder, said the system is purpose-built for high-tempo operations, contested operations, and the growing role of autonomous systems in modern defense. He added that Warden brings together wide-area, real time, hyperspectral optical sensing powered by the ARK software.
Sovereign Capability and Delivery
Following the down-selection in November 2025, where Warden outperformed advanced sensing technologies from around the world, Arkeus worked closely with the Australian Army and Insitu Pacific to validate the sensor. The Australian Army confirmed acquisition of the first tranche of Warden systems for deployment with the TUAS, delivered and sustained by Insitu Pacific. Duggan said the successful integration showed how rapidly cutting-edge capabilities can be fielded and highlighted the platform's readiness to pair with advanced Australian sensing technology.
The entry of Warden into Australian Army service marks a notable step in the TUAS Program's evolution and in the broader adoption of AI-enabled sensing for tactical operations. The collaboration among Arkeus, Insitu Pacific, and the Australian Army illustrates how sovereign industry partnerships can accelerate the delivery of advanced defense capabilities. With the first tranche confirmed, the program positions the Australian Army to improve domain awareness, decision superiority, and operational effectiveness in contested environments.
