Japan is building suicide drones out of cardboard, and before you laugh, consider the strategic logic: at $2,000 per unit, you can afford to lose them.
The AirKamuy 150, manufactured by startup AirKamuy, ships in flatpack format - think IKEA furniture, but for disposable military drones. According to 404 Media, Japan's Defense Minister Shinjirō Koizumi confirmed the Japan Maritime Self-Defense Force is already deploying them.
The official line is that they're being used "as targets" - training systems for anti-drone defense. But let's be honest about what a disposable, low-cost, suicide drone platform is actually for: overwhelming air defenses through sheer numbers.
Modern air defense systems cost millions. Each interceptor missile costs tens of thousands of dollars. If you can build drones for $2,000, you can launch swarms that cost more to shoot down than to deploy. The math favors the attacker.
This is the drone warfare evolution we've been watching in Ukraine: cheap, expendable systems that force adversaries to either waste expensive countermeasures or accept damage. Japan is adapting that doctrine, but with the manufacturing efficiency you'd expect from the country that perfected just-in-time production.
Cardboard makes sense for this use case. It's lightweight, cheap, biodegradable, and doesn't trigger metal detectors. It won't survive long in combat conditions, but that's the point - these aren't reusable assets. They're single-use weapons that arrive flat-packed and get assembled in the field.
Koizumi stated that Japan aims to "become the Self-Defense Forces that makes the most extensive use of unmanned assets, including drones, in the world." That's diplomatic language for: we're betting our defense strategy on cheap autonomous systems instead of expensive traditional hardware.
