Japan Approves Mass Production of 3D-Printed Terra B1 Interceptor Drones

A Fast Track to Production

Japan's Acquisition, Technology and Logistics Agency signed a mass production procurement agreement for the Terra B1 interceptor drone, a 3D-printed unmanned system designed to shoot down low-cost attack drones such as the Shahed. The agreement marks the latest step in Japan's effort to deploy a large drone fleet by 2027.

What stands out is the speed. The tender process took three months from release to decision, compared to one to two years for previous bids. The agency selected Terra B1 after a live demonstration with the Maritime Self-Defense Forces last month, beating out 38 competing firms.

Why 3D Printing Matters Here

Terra B1 is built using additive manufacturing, which is central to the program's logic. Traditional aerospace manufacturing requires tooling, long lead times, and supply chains that are hard to scale quickly. 3D printing removes those constraints.

Using 3D printers will simplify and shorten the design and prototyping stage, said Terra Drone CEO Toru Tokushige. It also means the company can modify the interceptor as threats evolve without disrupting the deployment schedule. That adaptability matters when you are facing drones that change faster than conventional procurement cycles.

Terra Drone plans to distribute production across multiple sites and eventually expand to local printing farms. Even if one facility were attacked by a system such as a Shahed-type drone, the distributed model could significantly reduce the risk of the entire supply chain being disrupted.

The Terra B1 in Context

Terra B1 is the Japan-made counterpart to Terra A1, which has been operating on Ukraine's battlefields since earlier this year. The A1 has a maximum speed of about 300 kilometers per hour, an operational range of up to 32 kilometers, and an endurance of approximately 15 minutes. It costs around $2,500 to $3,000 per unit, which is roughly what a single Shahed drone costs. That economics equation is the entire point: shooting down cheap attack drones with cheap interceptors rather than expensive missiles.

Terra Drone is not a startup. The listed company has more than 650 employees and has been operating for over a decade. It acquired and integrated Ukrainian drone maker Amazing Drones as a subsidiary, giving it direct exposure to the fast-evolving counter-drone tactics being developed in Ukraine. That battlefield experience is a meaningful competitive advantage over the 38 firms that lost this bid.

Japan's Broader Shift

Japan has an early history with 3D printing. The first Japanese 3D printer, the CMET SOUP, appeared in 1998. Pioneering work from companies like Teijin Seiki and Mitsubishi helped establish the technology in Japan. But the country has been slow to adopt additive manufacturing at scale compared to the U.S. and Europe.

That is changing. TDK acquired Fabric8Labs in a deal worth up to $400 million. Sodick bought Prima Additive, now called Altform. Japanese machine tool manufacturers continue to invest. The Terra B1 program is a clear signal that defense procurement in Japan is now treating additive manufacturing as a core capability rather than a fringe technology.

The practical impact for makers and the broader 3D printing industry is straightforward: when a major military customer puts real money behind distributed 3D printing for production, it validates the technology in ways that consumer or even industrial customers cannot. Japan is not just buying drones. It is betting on a manufacturing model that every defense industry will be watching.
