Japan aims to catch up on drone warfare by tapping Ukraine’s experience - SCMP

Japan is accelerating its development of drone-based defense systems by drawing on battlefield-tested technologies from Ukraine, aiming to close a gap in its military capabilities. The Japanese Ministry of Defense has launched a major initiative to deploy high-speed interceptor drones by 2027, with the goal of protecting critical infrastructure from long-range drone threats. This strategic shift is being managed by the Acquisition, Technology and Logistics Agency, which has finalized plans for a domestic drone interceptor network.

The decision follows successful field tests of Japanese-developed drones in Ukraine, where two models—Terra A1 and Terra A2—demonstrated their ability to neutralize incoming threats at speeds exceeding 300 kilometers per hour. These tests met a key requirement set by Japanese defense officials: that any new system must have proven combat experience.

In parallel, Japan is considering the purchase of Ukrainian-made combat drones for its Self-Defense Forces, as reported by Kyodo News on drone purchase. The move reflects growing international interest in Ukrainian unmanned systems, which have been rapidly refined through real-world conflict. Japan’s Ministry of Defense has allocated 277.3 billion yen budget (about $1.7 billion) in its 2026 fiscal year budget for the development and acquisition of unmanned systems.

The country’s broader defense strategy, known as Synchronized, Hybrid, Integrated and Enhanced Littoral Defense (SHIELD), emphasizes the use of reconnaissance and strike drones to defend remote islands and maritime assets. By leveraging Ukraine’s combat experience and technological adaptability, Japan aims to build a cost-effective and sustainable defense posture in an increasingly contested security environment.
