The K-RACER project originally began with the goal of developing a high-speed unmanned aircraft. At the defense equipment exhibition “DSEI Japan 2023,” held in March 2023 in Chiba Prefecture, the “K-RACER-X1,” which combined the advantages of both helicopters and fixed-wing aircraft, was showcased. During the development process, however, it became clear that there was a high demand for heavy cargo transportation, leading to the development of the K-RACER-X2.
The K-RACER-X2 aims for a maximum payload capacity of 200 kg, a flight range of over 100 km, and the capability to operate in mountainous areas with altitudes of around 3,000 meters. This makes it suitable for transporting supplies from the base of mountains to mountain lodges. Additionally, the aircraft’s ability to transport heavy cargo could prove useful in disaster relief efforts, particularly in delivering supplies to affected areas.
Furthermore, K-RACER-X2 is drawing attention for its potential defense applications. In January 2024, a test was conducted at the JMSDF Yokosuka Base, in cooperation with the experimental ship Asuka, where approximately 30 kg of supplies were suspended from the K-RACER-X2 and lowered from the pier to the deck of the vessel. According to a Kawasaki Heavy Industries representative, this test was conducted using a moored vessel for safety reasons, but in actual operations, it is envisioned that supplies would be transported to ships while they are underway.
Additionally, the JMSDF is conducting research on detecting targets beyond the horizon, which cannot be captured by ship-mounted radars, using radars installed on rotary-wing unmanned aircraft. Specific research on this will begin under the Acquisition, Technology & Logistics Agency (ATLA) starting in fiscal year 2025. Kawasaki Heavy Industries has indicated that it is considering performance enhancements to meet customer demands, and the K-RACER-X2 could be equipped with various sensors and communication devices. This suggests a potential connection between the two projects, raising further interest in their developments.
