Japan approves mass production of 3D-printed interceptor drones

MANILA, Philippines — Japan’s defense-procurement agency has signed a mass production procurement agreement for interceptor drones made using 3D printers, the latest move to rapidly deploy a large unmanned fleet by 2027.

The Acquisition, Technology, and Logistics Agency selected Terra B1, a rocket-launched interceptor drone, after a demonstration with the Maritime Self-Defense Forces last month.

Terra B1 is developed by domestic industrial giant Terra Drone and serves as the Japan-made counterpart to Terra A1, which had been fielded on Ukraine’s battlefields earlier this year.

ATLA neither disclosed the number of units on order nor the contract price.

In late May, the defense ministry released a tender to rapidly acquire and deploy drones that can intercept one-way attack drones such as the Shahed and anti-radar loitering munitions such as the IAI Harpy.

The latest decision is the fastest to date, industry insiders say, as the tender took only three months compared to previous bids which took one to two years.

The decision also reflects the government’s growing efforts to increase 3D printing capabilities to support defense needs.

Using 3D printers will “simplify and shorten” the design and prototyping stage, CEO Toru Tokushige told Defense News. It will also allow Terra B1 to move into mass production as quickly as possible and meet contract requirements.

Aside from lowering costs and accelerating production, 3D printing will allow the company ample time to modify the interceptors to adapt to evolving threats and the fast-changing drone tech landscape without delaying the deployment schedule.

Terra Drone also plans to spread out production across multiple locations, and later expand to local printing farms, as a precautionary measure to ensure manufacturing can continue even if one facility comes under attack.

“Even if one production site were attacked by a system such as a Shahed-type drone, this distributed model could significantly reduce the risk of the entire supply chain being disrupted,” Tokushige said.

3D printing has been changing military and defense logistics since the U.S. Army and Navy deployed printers in the field in 2012. In Ukraine, printing farms have become a frontline

necessity: They produce drone parts and a range of tools to support brigades in the ongoing war.

The defense ministry’s decision to adopt the technology signals a massive shift in the defense industry, which experts warn may be unable to keep pace with the current administration’s export drive and increasing global demands.

“We believe 3D printing is not simply about reducing manufacturing costs. It has the potential to transform Japan’s defense manufacturing into a faster, more flexible and more resilient production model,” Tokushige said.
