JISDA Begins Provision of 'Shiraha', a Fully Domestic Fixed-Wing Drone Costing 70,000 Yen
JISDA Co., Ltd. has launched the 'ACM-01 Shiraha', a fully domestic fixed-wing drone designed for training. Made of wood with a 1.9m wingspan and costing only 70,000 yen, it was developed based on lessons from the Ukraine war, prioritizing continuous, expendable training over the use of expensive, high-performance units.

JISDA Co., Ltd. (Japan Integrated Security Design Agency, Chiyoda-ku, Tokyo, CEO: Shota Kunii, hereafter 'JISDA') is pleased to announce that it has begun providing the fully domestic fixed-wing drone 'ACM-01 Shiraha'.
'Shiraha' is a fixed-wing unmanned aerial vehicle for training and short-range operational use, adopting a wooden airframe structure. With a wingspan of 1.9m, it is constructed entirely domestically, down to its components. By narrowing down the specifications to the absolute minimum required for training purposes, we achieved a cost of 70,000 yen.
This aircraft is designed not on the idea of operating a small number of highly expensive, high-performance machines, but on the premise of being continuously used in training environments, thereby enhancing the operational capability itself while allowing for attrition and replacement as necessary. Through the provision of 'Shiraha', JISDA will support the creation of an environment where continuous fixed-wing drone training can be conducted in more field locations.

■ Background of the Launch
JISDA and the Unmanned Asset Consortium 'RISE' have been promoting cross-sectional initiatives covering the R&D, manufacturing, operation, and logistical support of unmanned aerial vehicles, robotics, and AI from the perspective of defense and technological security. RISE is not a framework for making a single product, but a framework for connecting technology with operations, the field with policy, and R&D with manufacturing, maintenance, and supply, thereby building a foundation for an unmanned asset industry in Japan that can be continuously improved. 'Shiraha', which JISDA is now offering, is positioned as an extension of this philosophy.

Particularly in the domain of unmanned aerial vehicles, the supply system itself—how to secure necessary components, where to manufacture them, how to replenish them, and how to recover when attrition occurs—becomes a part of the operational capability, not just the performance of the aircraft alone. JISDA is pioneering a domestic supply chain through RISE, recognizing the issue that even if excellent elemental technologies and manufacturing capabilities exist domestically, they are not sufficiently connected and struggle to function as an integrated operational base. 'Shiraha' is a fixed-wing drone developed with the vision of creating a system that can continuously supply the quantities needed for training, predicated on a fully domestic composition.
The background to this problem awareness lies in the experience of the JISDA founding team, who conducted continuous field research in Ukraine for about three years even before the corporate establishment. The investigation extended beyond the capital and rear areas to regions near the Russian border and the vicinity of the front lines actually affected by combat, reaching as close as 20km from the front line. There, they continuously observed, listened, and analyzed how equipment is used in what environments, how it is worn down, how it is modified, and what operators truly need.
One of the vital lessons JISDA learned from this is that equipment is not something that is finished once completed. In modern drone warfare, equipment is used, countered, broken, retrofitted, and used again. On the front lines, frequencies, video transmission, navigation, antenna placement, airframe configuration, and payload handling are reviewed on a weekly basis, or sometimes even shorter spans. The very system that allows for continuous training, replenishment, and improvement is part of the military strength. JISDA believes that we must learn from the reality of modern warfare, not to fight wars, but to prevent them and protect peace. 'Shiraha' is one attempt to incorporate these lessons into the development of a training infrastructure in Japan.

Furthermore, JISDA's drone training, storage, and replenishment package 'Skill House' strongly emphasizes the importance of establishing an environment that enables continuous operation. Skill House aims to create a system where users can easily focus on the training itself by providing an integrated training environment premised on attrition, aircraft stock management, repair/replenishment support, and practical training. Similarly, in the domain of fixed-wing drones, JISDA believes that what is needed is an environment where people can 'fly enough, repeat necessary repetitions, and enhance their capabilities while factoring in attrition,' rather than 'not being able to train because they don't want to break it'.
