Praetorian Aeronautics is collaborating with the University of Adelaide on a Defence Trailblazer-funded initiative to develop HADRIAN, an advanced AI-enhanced counter-swarm system designed to revolutionize command and control for autonomous defence platforms.
HADRIAN aims to address the growing threat posed by low-cost, swarm-capable drones, a challenge that has become increasingly evident in conflicts such as those in Ukraine and the Middle East. These drone swarms have demonstrated their ability to overwhelm traditional defence systems, particularly in environments where GPS and communications are compromised.
Defence Trailblazer is a collaborative initiative aimed at strengthening Australia’s defence capabilities. This partnership involves the University of Adelaide, the University of New South Wales and over 50 industry partners nationwide. The program focuses on coordinating cross-sector research and training to boost Australia’s defence innovation capacity.
The initiative has secured a total investment of $240 million over four years, which includes a $50 million commitment from the Australian government, matched by the university partners, and an additional $140 million contribution from industry partners.
Enhancing autonomous counter-swarm solutions
The project focuses on leveraging multi-agent reinforcement learning (MARL) AI techniques to enhance HADRIAN’s capability to rapidly integrate and process data from air, ground and maritime sensors. The research will refine MARL AI algorithms to improve the system’s ability to detect, classify and prioritize complex moving threats.
Once threats are identified, HADRIAN will determine and execute the most effective swarming countermeasures, significantly reducing the sensor-to-effector cycle and operator workload.
Brett Hill, CEO of Praetorian Aeronautics, emphasized the significance of AI-driven capabilities:
“HADRIAN is powered by frontier algorithms in the field of multi-agent reinforcement learning to enable the system to realize ‘Any Sensor, Best Effector’ sensor fusion,” said Hill. “This system will help protect the Australian Defence Force and its allies from threats that have already proven capable of overwhelming current air defence systems and continue to evolve.”
The collaboration with the University of Adelaide will allow for extensive research into various single-agent solutions and their behaviors across multiple scenarios, including those focused on resilience and robustness.
Associate Professor Claudia Szabo, Defence Trailblazer’s Theme Lead for Robotics, Autonomous Systems, and AI, highlighted the importance of this research:
“This project will allow for the exploration of many single-agent solutions and a deep understanding of their behaviours across many scenarios,” Szabo stated. “The research project will help the Defence sector experiment with methodologies and techniques to effectively defend against various drone threats that exist now and those that are emerging, and will help to design cost-effective counter solutions to these problems.”
A key outcome of the project is the proof-of-concept prototype, which will integrate highly mobile ground-based and air-launched counter-UAS interceptors into an advanced area defence system. This system will be capable of countering AI-powered drone swarms, providing a critical capability enhancement for modern defence forces.
Dr. Margaret Law, General Manager of TDA at Defence Trailblazer, reinforced the significance of the partnership:
“Praetorian has been an active partner of Defence Trailblazer, collaborating and participating in both workforce and research and development projects,” said Law. “We’re pleased to be supporting this project, which delivers critical capability to the ADF and its allies.”
With this partnership, Praetorian Aeronautics seeks to drive forward scalable, cost-effective autonomous countermeasures, staying ahead of the rapidly evolving challenges in drone defence. The HADRIAN project looks to add new capabilities to ensure modern defence systems remain resilient against increasingly sophisticated and unpredictable threats.
