JISDA Inc. (Japan Integrated Security Design Agency, Chiyoda-ku, Tokyo, Representative Director: Shota Kunii, hereinafter "JISDA") is pleased to announce that it has begun offering the fully domestically produced fixed-wing drone "ACM-01 'Shiraha'."
"Shiraha" is a fixed-wing unmanned aerial vehicle designed for training and short-range operational use, featuring a wooden airframe structure. With a wingspan of 1.9m, it is entirely domestically produced, including all components. By focusing on the minimum specifications required for training purposes, a manufacturing cost of 70,000 yen was achieved.
This aircraft is not designed with the idea of operating a small number of expensive, high-performance machines, but rather with the premise of continuously using it in training environments, and enhancing operational capabilities by wearing out and replacing units as needed. Through the provision of "Shiraha," JISDA aims to support the creation of environments where continuous fixed-wing drone training can be conducted in more locations.

■ Background of Provision
JISDA and the unmanned asset consortium "RISE" are promoting initiatives to comprehensively advance research and development, manufacturing, operation, and logistical support for unmanned aerial vehicles, robotics, AI, and other technologies from the perspective of defense and technological security. RISE is not a framework for creating a single product, but rather a framework for connecting technology and operations, field and policy, and R&D with manufacturing, maintenance, and supply, to build a continuously improvable unmanned asset industry base within Japan. The "Shiraha" that JISDA is now offering is an initiative positioned as an extension of this philosophy.

Particularly in the field of unmanned aerial vehicles, not only the performance of the aircraft itself, but also the supply system—how to secure necessary parts, where to manufacture them, how to replenish them, and how to recover from wear and tear—becomes part of the operational capability. JISDA recognizes the challenge that even with excellent domestic elemental technologies and manufacturing capabilities, they are not sufficiently connected, making it difficult for them to function as an integrated operational base. Through RISE, JISDA is promoting the development of a domestic supply chain. "Shiraha" is a fixed-wing drone developed with a focus on establishing a system that can continuously supply the quantities required for training, based on a fully domestically produced configuration.
Behind this awareness of the problem is the experience of the JISDA founding team, who conducted continuous on-site investigations in Ukraine for approximately three years even before the company's establishment. These investigations extended not only to the capital and rear areas but also to areas near the front lines affected by combat and close to the Russian border, with the closest point being about 20km from the front line. There, they continuously observed, listened, and analyzed how equipment was used in what environments, how it wore out, how it was modified, and what operators needed.
One of the important lessons JISDA learned from this is that equipment is not a one-time completion. In modern unmanned aerial vehicle operations, equipment is used, countered, broken, modified, and used again. On the front lines, there is a reality where frequencies, video transmission, navigation, antenna placement, airframe configuration, and payload handling are reviewed weekly, or sometimes even more frequently. The system itself, which can continuously train, replenish, and improve, has become part of the combat power. JISDA believes that to prevent war and protect peace, we must learn from the realities of modern warfare. "Shiraha" is one attempt to apply that learning to the development of a training infrastructure in Japan.

Furthermore, the importance of creating an environment for continuous operation is strongly emphasized in JISDA's drone training, storage, and replenishment package "Skill House." Skill House aims to create a system where users can concentrate on training itself by providing a training environment that assumes wear and tear, aircraft stock management, repair and replenishment support, and practical training as an integrated package. JISDA believes that in the field of fixed-wing drones, similarly, an environment is needed where one can "fly sufficiently, repeat the necessary number of times, and improve capabilities while accounting for wear and tear," rather than "not being able to train because one doesn't want to break it." "Shiraha" is an aircraft based on this philosophy, aiming to achieve the minimum specifications required for fixed-wing aircraft training at an accessible price point.

■ Features of "Shiraha"
1. Wooden, Fully Domestically Produced Fixed-Wing Drone
"Shiraha" adopts a wooden airframe structure and is entirely domestically produced, including its components. It is not merely assembled domestically but is designed to be easily connected to a supply system that encompasses domestic procurement of materials, manufacturing, assembly, inspection, and quality control. This aims to achieve both continuous supply and rapid improvements in response to field needs.
2. Minimum Spec Configuration for Training at a Manufacturing Cost of 70,000 Yen
The 70,000 yen manufacturing cost of "Shiraha" is based on a configuration that focuses on the minimum necessary specifications, assuming its use for training. In training environments, it is important not to fly cautiously only a limited number of times, but to fly a sufficient number of times and refine piloting, maintenance, and operational judgment through experience, including failures. JISDA believes that in training environments where a large number of aircraft are expected to be consumed, not just high performance, but a pricing design that allows for repeated use leads to practical value.
3. Expandable Design for Short-Range Operations
"Shiraha" is a fixed-wing drone designed for short-range operational use in addition to training. The presented manufacturing cost of 70,000 yen is for the minimum spec configuration primarily for training purposes; the price will increase depending on the application if extensions to flight range, enhancement of communication performance, or addition of various functions are made. On the other hand, JISDA believes that a design philosophy that first provides a low-cost aircraft as a training foundation and then allows for necessary expansions is practical for field operations.
■ Comment from Representative Director, Shota Kunii
We believe that being fixated on the drone airframe itself is not essential. For engineers and those familiar with radio-controlled models, building a flying aircraft itself is not particularly special, and if cost is not an issue, specifications such as payload, flight range, and communication performance can be increased to some extent.
However, an unmanned aerial vehicle that can be deployed in modern combat is not merely an aircraft that flies. The technological concept of an unmanned flying object has existed since around the 18th century, and the value of current unmanned aerial vehicles is only established through the integration of multi-layered technologies and operations, such as network connectivity, real-time processing, autonomy, anti-jamming capabilities, integration with operational tactics, and replenishability. In other words, rather than the airframe technology itself being revolutionary, we believe that defense innovation has become a reality due to the miniaturization and commercialization of technological elements, integrated control by software, and the establishment of social and industrial system receptiveness.
With this "Shiraha," we started by asking how much we could reduce the price while maintaining the minimum necessary specifications. The figure of 70,000 yen for the manufacturing cost is not just for price appeal. We want to change Japan's mindset from the idea of using expensive aircraft in limited situations to viewing unmanned aerial vehicles as a service and solution that can be repeatedly used in the field.
Furthermore, we do not believe there is a need to excessively revere the material itself. While wood is a characteristic, the material itself is not the essence. What is important is the balance between control quality and cost. It might be more optimal overall to flexibly operate multiple inexpensive aircraft rather than perfecting a single aircraft with extremely high precision, and it is possible to reduce the overall system cost through ingenuity in swarm control and sensor allocation. We believe that value should be considered within the overall operational design, not just single-unit performance.
The industrial structure of the 21st century has changed significantly with the integration of hardware and software. While the performance of the product itself was once the source of value, today, the ability to design "things"—that is, what kind of experience, meaning, and order are provided through them—is at the center of competition. "Shiraha" is an aircraft born from this understanding of the times. We position this aircraft not merely as a single product, but as a starting point for creating a cycle of innovation in unmanned aerial vehicles in Japan.
