Terra B1 is a Japan-made interceptor drone developed to counter long-range loitering and one-way attack UAVs. It was the only aircraft to pass Japan ATLA’s 2026 rapid-acquisition demonstration and entered mass-production procurement in August 2026.
About
Terra B1 is Terra Drone’s domestically produced counter-UAS interceptor for long-range loitering threats such as Shahed-type drones. Japan’s Acquisition, Technology & Logistics Agency selected it from a 38-company proposal process and tested it alongside three other aircraft between July 15 and August 6, 2026.
Terra Drone says Terra B1 was the sole platform to pass the demonstration. ATLA then signed a mass-production procurement contract on August 25, moving the aircraft from evaluation into an implementation programme that includes production, spares, batteries, communications, control equipment, maintenance and operator training.
