US autonomy software firm Shield AI and Japan’s Mitsubishi Heavy Industries demonstrate rapid AI integration for defence drone operations.
Shield AI and Mitsubishi Heavy Industries (MHI) have completed autonomous flight tests in Japan, integrating Hivemind software onto MHI’s ARMD drone platform in fewer than 60 days.
The tests took place in Ota City, Gunma Prefecture. Two live flight demonstrations featured MHI’s Affordable Rapid-Prototyping Mitsubishi-Drone aircraft flying without human input, using reinforcement learning to track a virtual air vehicle.
The first flight saw Hivemind autonomously direct an ARMD to pursue the simulated target. The second pushed the system harder, executing more aggressive pursuit manoeuvres on a separate aircraft. Both drones coordinated movements in real time, according to Shield AI.
A Compressed Development Timeline
The integration timeline proved as significant as the flights. MHI engineers moved from software-in-the-loop to hardware-in-the-loop testing in under two weeks — previously a months-long process. Vehicle-in-the-loop testing followed within a further two weeks.
Takahiro Katoji, director of MHI’s Uncrewed Aerial Systems Department, said previous development required engineers to maintain complex environments spanning coding, AI training, simulation, and hardware verification. Using Hivemind Enterprise shifted focus directly onto mission autonomy development, he said.
The Software Behind the Flights
Hivemind is Shield AI’s core AI pilot software. It enables aircraft to sense their environment, make decisions, and act — without pre-programmed routes or a communications link. It can reroute dynamically, avoid obstacles, and respond to unexpected conditions in real time.
Shield AI CTO Nathan Michael said the collaboration showed Hivemind’s capacity to compress development timelines. “Each flight test marks one step closer to operationalising at scale,” he said.
Japan’s Broader Defence Push
The tests carry weight beyond the flight line. Japan has committed to doubling annual defence spending to roughly two percent of GDP by 2027. Uncrewed and autonomous systems sit at the centre of that build-up, as Tokyo works to strengthen deterrence amid regional tensions.
MHI is one of Japan’s primary defence contractors. The exercise validates a faster route from concept to deployable platform. For Shield AI, the partnership deepens its presence in the Indo-Pacific defence market.
Neither company announced a specific procurement programme or deployment timeline.
